Looking beyond surplus value for keeper decisions
I stared at the two options for a long time.
Russell Martin as a 21st-round pick.
Dee Gordon as a 3rd-round pick.
I referred to my projections for each, the replacement level at their position, the surplus value over the expected return in each draft slot. I stared. I went for a run. I came back, stared.
Keeper decisions shouldn’t take this large a toll, but there were extenuating circumstances in this case. I’d just inherited a team, one I’d named Revenge of the Nameless Ranger in anticipation of Modern Baseball’s upcoming May album release, and I was still acclimating myself with the league format and rules. It seems like a great league, a 12-team 8X8 (OBP, SLG, K, QS, HLD, HR) with a high enough buy-in to prevent malaise, with a hybrid roto-head-to-head scoring system and well-developed keeper rules.
I also took last year off, to a degree, putting aside fantasy analysis due to an exclusivity clause that kept me bound to basketball only a season ago. I still played, of course, but not to the depth I had in previous years. I’ve spent most of the offseason shaking any residual rust off, but this was still my first major keeper decision of the year (and my first kick at the can at self-made projections instead of just self-made values built from Mike Podhorzer’s projections).
There was also the matter of Martin and Gordon being two of my favorite players in baseball, the former a similarly well-bearded Canadian for my Toronto Blue Jays and the latter one of those past sleeper hits that sticks with you for the residual hubris. Looking at fantasy in strictly analytical terms, that shouldn’t matter in the least, as numbers are numbers and value is value. But fantasy sports are also supposed to be fun, and an attachment to a player is an entirely justifiable tie-breaker, at least in my books.
But it was no help in this case, because they’re both great.
The decision, then, came down to factors outside of just perceived surplus value or fandom – they weren’t exactly even in each, but close enough that the decision remained difficult.
Even if the surplus value of one had appreciably outstripped the other, there are mitigating factors that can complicate a decision beyond just the raw numbers. I know there are some analysts and players who employ a strategy that would disagree with that, but in most league formats, there’s nuance beyond just Production Over Cost.
In this case, a few other factors come in to play.
The primary one I considered was where either player would fit with my other keepers, all of who were much easier decisions. All four also happen to be hitters, and since my fifth keeper would also be a hitter, I know going in that the draft is going to be paramount to my pitching staff. Given the top-heavy nature of pitching this year, with as many as 18 ace-calibre arms, I grew more confident in keeping Martin, because the value of that third-round pick to my staff was too high.
Gordon has a first-round average draft position, and getting a player like that who can help dominate an individual category in the third round is great. But the 29th overall pick is also likely to land me a quality arm, and “Martin+3rd-round arm” felt like a better proposition than “Gordon+SP flier in the 21st round.”
There was also the matter of replacement-level at either position. I had quantified it already in creating my values, but looking beyond the numbers was instructive. In a 12-team league with one catcher, no middle infield, and only one utility spot (and eight bench spots), the replacement level at either position is going to be roughly the No. 15 or 16 player at the position, maybe higher.
At catcher, that’s getting into Nick Hundley–Wilson Ramos–Francisco Cervelli territory (or, in some leagues, Yadier Molina Flier territory), solid players, to be sure. At second, you might get a Ben Zobrist or Logan Forsythe, and it’s where you could take a moderately trendy sleeper in Jonathan Schoop. I actually don’t mind the replacement-level options at either spot, and in the event Martin were to get hurt, there are reasonable short-term fill-ins likely to be on the wire.
In terms of who may be draftable at each spot, the ADPs break down something like this for a 12-team.
Catcher
2nd: Buster Posey
9th: Salvador Perez, Jonathan Lucroy
10th: Brian McCann, Russell Martin
12th: Travis d’Arnaud
13th: Devin Mesoraco, Matt Wieters
14th: Stephen Vogt, J.T. Realmuto
15th: Yan Gomes
16th: Yasmani Grandal
17th: Blake Swihart
Second
1st: Jose Altuve
2nd: Dee Gordon
4th: Robinson Cano
6th: Brian Dozier, Anthony Rendon
7th: Jason Kipnis
8th: Ian Kinsler, Rougned Odor
11th: Addison Russell
12th: Kolten Wong
13th: D.J. LeMahieu
14th: Daniel Murphy, Dustin Pedroia
16th: Starlin Castro, Ben Zobrist
There are a couple of ways to look at those lists. One is to note that catchers, in general, are going later than their second-base counterparts, by ranking, and then Gordon might make more sense to beat a tough keystone market. That’s a strong argument against Martin, as you can generally wait longer on a catcher than a second-baseman.
But again, the martin keeper comes 18 rounds later, and instead of Martin or Gordon, the decision starts to build to something like this:
An SP in the third round, a second baseman in the sixth round, a starter in the 13th round, and Martin in the 21st round
OR
Gordon in the 3rd round, an SP in the sixth round, a catcher in the 13th round, and an SP flier in the 21st round
(This is all just rough and obviously you’re not going to hold yourself to a certain position with each pick, but it’s meant as an illustration of how building out the entire roster will happen.)
My personal preference is to have a sure thing with a very late pick and then a top-30 overall pick in hand. Gordon is awesome, and I’m not in the camp that foresees a 2016 decline, but I also think Martin could wind up the No. 2 catcher in fantasy this season, especially if he eventually winds up leading off for the Blue Jays. The flexibility having that third-round pick provides – especially in my first year having inherited a team – is big to me.
And so I chose Martin. I’d be interested to hear if and why people disagree, though that’s not really why I wrote this. After spending the bulk of a week sorting through numbers and creating projections and rankings, the decision on my fifth keeper served as a reminder that draft decisions extend beyond the spreadsheet.
And that it’s OK to just make a gut call and go with the best smile in baseball.

If it was independent of the pick where you selected the player, would you still go with Martin or does the 18 round difference not make up as much ground?
If they didn’t cost a pick at all? I’d have to go Gordon. Even with scarcity, that’s a 1st-rounder vs. a 10-12th rounder.
I play in a 16-team keeper league where we keep 12 MLB players each offseason with no limits on years kept and no rounds/picks attached to them. We just draft all the unkept MLB players each new season in a snake draft based on place finished last year.
I hear you on all the factors beyond straight numbers that can go into making keeper decisions. I have to estimate career value and balance it vs. expected upcoming season production. Gut feel tends to trump all the formulas and permutations of them that I come up with when factoring aging/park effects/org tendencies/contract situations/likelihood of positional switches on top of production.
I can see playing the field with that 3rd rounder vs. committing to Gordon at a round where he doesn’t have a high probability of earning value over the draft slot.

When in doubt, pick the Blue Jay.
I’m dealing with a really tough one myself. We keep 4 each year, and my first three are easy:
Harper ($20)
Syndergaard ($6)
M.Betts ($15)
The 4th comes down to a hitter and a pitcher:
Kluber ($15)
Schwarber ($10)
For background, with inflation, a top-tier starter like Kluber should go for $27-$32 (so, ~$15 savings). Schwarber’s a little tougher, as projections for him are all over the place. If he gets enough ABs and you set replacement value high, he could easily be worth $25. But if you don’t buy his ability to reproduce, say, 80% of last year’s power, his low average could be a killer.
Schwarber is the boom-or-bust play, while Kluber is a little safer. Thoughts?
Both of them hold approx 15$ in surplus value, but Schwarber has way more risk
The decision is easy, it’s just giving up that much value that makes it hurt
It doesn’t look like you specified how many years a player can be kept. That’s a huge factor as well. If a player can be kept forever at that round value that increases Gordon’s value while depressing Martin’s.
Catcher is I think the most volatile position in fantasy. Martin had some nice numbers last year, but you could argue his counting stats were the best they’ve been since his early Dodger days.
Gordon, otoh, is in his prime, and in addition to what seems like being a lock for 40-50 sb, he also knows how to hit. SBs are at an all time low.
I take Gordon and I don’t even think it’s close. Draft Swihart or Realmuto later in the draft.
You’re welcome.
Players can be kept indefinitely but there is an appreciation tax if they out-perform their keeper cost. I didn’t want to fill a couple hundred words of space explaining intricacies when the specific choice wasn’t really the point of the article.
I have a predicament in my 13 hitting vs. 13 category pitching league
My keeper options
Arrieta 6th
Sano 13th
Marte 15th
Syndergaard 18th
Encarnacion 19th
Keuchel 20th
I get to keep 3 of those. The other 9 teams are keeping mostly hitters, a lot of top tier OF off the board, and only 3-4 SP being kept. I’ve been debating cornering the starting pitcher market by keeping 2-3 options but with injury risk and a lot of power and good hitting off the board I’m not sure the best route to take.
Carlos Carrasco as an 8th rounder or Danny Salazar as a 14th rounder? I like Carrasco better (as do most projections/rankings), but not sure that I like him 6 rounds better.
Also, with the keeper cost escalator in my league, Carrasco will probably be close to regular value as a keeper next year, while Salazar should have at least one more year of surplus value. And he’s two years younger, maybe a bit more potential for improvement.
Carrasco. Salazar saw a dip in his second half performance and his fly-ball tendencies will always leave him homer-prone.
Martin is the correct choice and it’s not even close for me. Gordon’s atrocious walk rate means that he’s entirely dependent upon balls in play, and he’s not hitting .383 on those in 2016. Furthermore, his concentrated value limits what parts of the draftable player pool fit with your team, and he’s one significant hamstring injury away from having almost no value at all. To me, Gordon is poised to be one of the 2016’s biggest fantasy disappointments.
This is wrong for reasons I spelled out above for a few reasons. But additionally:
You only truly get burned if he gets hurt (which is true of any player). His best skill, his speed, makes him a near-lock for 40-50 sb which has now become the scarcest roto commodity. Add in the fact that he provides a net positive in AVG and R and I think his floor is pretty high.
Cather is the most volatile fantasy position and even the best catchers (see: Posey, Buster) don’t come close to providing the value that top players at other positions do. And Buster is so far above the other catchers that taking a flier on a late round catcher is almost always the best play.
I did not find your “reasons” to be compelling. Martin’s counting stats significantly improved last season because he was hitting in a vastly superior lineup, something that will remain true in 2016. And while Gordon is younger, stolen bases decline at an earlier age than power, so he’s actually exiting his prime rather than being in it.
Speedsters are more susceptible to an injury affecting their value than other players because things like hamstring strains are more common while significantly affecting stole base accumulation.
Gordon’s low walk rate suppresses his OBP and therefore limits his run-scoring opportunities, which is why he ended up with only twelve more runs scored last season than Martin. And if his BABIP experiences a major regression as expected, then Gordon’s value in batting average and runs will be significantly affected.
On what basis are you making this claim? I have not found this to be true.
I don’t think you’re familiar with the concept of replacement value. How the raw stats of the best catchers compare with the raw stats of the best outfielders or first basemen isn’t relevant. What matters is how the best catchers compare to the replacement level at their position (measured from either the worst catcher who has to be used by someone or the best catcher who isn’t used).
My issue with this decision is that your analysis doesn’t seem to take into account devaluation of the draft picks in such a system. Guys who broke out the previous year like Arenado won’t be there and so many of the aces you’re waiting on will be gone by the 3rd round and that’s not even considering that the pool will be smaller due to them having been kept. I’d have to look at previous years’ draft results to get a sense of what’s available in the 3rd round to take stock of the pick. Maybe you’re right and that 3rd round pick could be nice, but if it’s true value is somewhere around 6th round (based on ADP), then you lost Gordon’s 1st/2nd round value for a 6th round pick rather than a 3rd round pick – which I don’t think helps counter the loss of SBs you’ll have to scrape up later when you could be taking flyers on starting pitching.
My 2 cents.
Well, I didn’t get into all of the intricacies of the league and keeper rules. (E.g. aces are likely to be available as the keeper rules are designed to discourage high-round keepers for too long). The point of the article wasn’t the specific decision, but what goes into it, and I didn’t want to sped a couple hundred words laying out rules that weren’t relevant to a broad audience.
For some reason there was no reply button on your follow-up.
First comment, I mean Gordon exiting is prime is debatable, but if he is exiting his, where does that leave a 33 year old catcher who’s logged a lot of time behind the plate…
Second comment: My point was more that speed doesn’t slump and I think you’d be hard pressed to find a lot of people who think Dee doesn’t still have a few top sb years still ahead of him.
Third: How major should it really regress? He hits a ton of balls on the ground and runs like the wind. Sounds like exactly the skillset that lends itself to high BABIPs year over year. Career BABIP is .346…
Fourth: Maybe catchers aren’t so much more volatile than every other position but just as volatile surely.
And gee. wow. thanks for introducing me to replacement value…Give me a break. How about the concept of finding the next inefficiency? I think we’re there with fantasy baseball. There’s infinite information out there and so if we’re all so smart how does one find an edge? Of course raw stats matter. At the end of the fantasy season do you take home the trophy if your VORP is highest? No. Total raw stats.
Extreme example. Schmuster Mosey is the #1 catcher. His year end number in a standard 5×5 are 20 hr, 75 rbi, 60 runs, .300 avg, 1sb.
Johnny Nobats represents every other catcher. Their lines are identical. 10 hr, 45 rbi, 40 runs, .250 avg, 1 sb.
If you were the one guy that jumps on Mosey I’d laugh while I collect your money because I can get Nobats in the last round. Simply, your advantage is small. The true stud I get the round you take Mosey, will crush your last round flier whom you probably cut week 1.

I didn’t say anything about Martin being in his prime, did I? You made the dubious claim that Gordon is in his prime when history tells us that his stolen base totals should begin declining substantially. Both players are presumed to be in their decline phase.
Of course speed slumps. Why on earth would you think otherwise? Your “points” continue to be vague generalizations without any actual evidence to support them.
He had never posted a BABIP higher than .346 prior to last season, so it’s likely that he’ll be there or something below that in 2016. If you split the difference between Steamer and ZiPS, that would give him a .338 BABIP and .288 batting average. That still has value, but not nearly as much as he accumulated in 2015.
You twice claimed that “Cather (sic) is the most volatile fantasy position,” so is this response an admission that your claim was wrong?
You have just made it completely clear that you do not understand the mathematics behind fantasy sports. If the difference between Schmuster Mosey and Johnny Nobats is larger than the difference between the difference between the top player and worst starting player at every other position, then you eschewing Mosey in favor of Nobats would result in you losing that league every single time. That’s the way math works. Fantasy value is relative, which is why you have to look at more than just the raw stats.
*facepalm*
Granted this will amount to nothing since its an argument over the internetz, but I would gladly pit my fantasy baseball results/success versus yours.
I’m not surprised you facepalmed yourself. I’d smack myself too if I didn’t understand common sense.
I’ve been writing about fantasy baseball professionally for 17 years. Your move.
All that means is that you are capable of writing. Well done. Do all broadcasters/commentators know what they’re talking about?
My move? I have an engineering degree, am versed in mathematics and happen to be an actuary (i.e. I am good at the maths). What’s your actual job? I peeped your website. Looks good. I’m gonna pass on the Fantasy Baseball Prospects 2014 though. Oh, and your screenshots are busted.
I haven’t lost money playing fantasy baseball since 2006. I play in some competitive leagues and I have more rings than fingers.
Consistent winner so I must be doing something right, yea?
You’ve shown that you don’t understand replacement value or how to reply to a post in the proper order, and you actually ended a post with “Drops Mic.” Convincing others of your expertise is going to be an uphill battle.
Not trying to convince anyone. Was just trying to help you overcome your mistakes.
You’re livin in the past man. Look to the future. It ain’t baseball for you. Maybe try fantasy curling?
Keeper decisions are tough…I’m in the same boat. What would you guys do? 12 teamer with OBP and Slug. Please help!
Xander Boegarts – $18
Hunter Pence – $11
Brett Gardner – $7
Could sneak in Shelby Miller @ $5 but I generally prefer the hitter over pitcher.
