Creating a Composite Jose Fernandez Projection
Jose Fernandez was having a dominating 2014 season until he needed Tommy John surgery last May. The 22-year-old righty could be one of the more dominant arms in the game when he returns. Fantasy owners would love to have him available mid-season as a boost their team. While he is on the disabled list (DL), some other pitcher must be filling in for him. Fernandez’s projection should include this replacement pitcher’s production. Here is a break down of how I put on value on players who will miss significant time.
Get a projection for the hurt player
Right now the only projection available for players is Steamer and here are Jose’s five category stats including innings pitched:
Wins: 10
WHIP: 1.13
K: 166
ERA: 2.96
Saves: 0
IP: 144
Fernandez’s rate stats may seem a bit high, but he is coming back from Tommy John surgery and pitchers initially struggle their first year back. I will keep them where they are at for now.
The main issue I have with the projection is the innings pitched. Right now the Marlins are expecting him back at the All-Star break, so 144 innings is out of the question. Also, the Marlins aren’t going to have him throw deep into games. I think 80 to 100 IP is more likely. I will go with 100 IP, but I could understand a more conservative value.
Find his first half replacement
While Hernandez is out, another pitcher will need to be on the roster taking his starts, accumulating counting stats (and bringing down the rate stats). In shallow leagues, the replacement effect is less because the available replacement level pitcher is better. As the league becomes shallower and shallower, the replacement level quality decreases. To get this replacement level pitcher, I would get the average value from three to four waiver wire/bench pitchers to create a composite replacement level pitcher.
In a shallow league I am in, Baltimore’s Miguel Gonzalez is the best available pitcher, so I will use his projection as my replacement level pitcher.
Wins: 8
WHIP: 1.36
K: 93
ERA: 4.56
Saves: 0
IP: 134
An owner will not need him for all 134 innings, so playing time can be adjusted down in the next step.
Mash the two two projections into one projection
Once you have the player’s projection and a replacement projection, combine both into one value. Here is a downloadable spreadsheet with the values filled in. Users will need to put in the 2015 projection in the first line and their projected innings pitched in the second line for both pitchers. Once the data is entered, a composite projection will be created.
Using the above values, Fernandez and his replacement should have the following stats:
Wins: 13
WHIP: 1.25
K: 185
ERA: 3.76
Saves: 0
Looking through the Steamer projections, here are some similar pitchers:
Ian Kennedy
Wins: 11
WHIP: 1.24
K: 186
ERA: 3.73
Saves: 0
Jeff Samardzija
Wins: 12
WHIP: 1.23
K: 178
ERA: 3.91
Saves: 0
James Shields
Wins: 13
WHIP: 1.20
K: 175
ERA: 3.62
Saves: 0
With every league being different, his value will not be comparable to these three pitchers. In some leagues, the composite will have higher quality comparable pitchers. In other leagues, the comparables will be worse.
Hopefully, I have helped you get an idea on how to set a draft/auction projection on a pitcher who will miss significant time. The key is to find the replacement level talent who will be in the lineup while the pitcher is out. Thanks and let me know if you have any questions.

If you are counting on a given replacement for the first 1/2 of the season, wouldn’t you have to use only 1/2 of his projected season stats, rather than assuming he will pitch 100 innings? A replacement level pitcher probably won’t pitch 100 innings prior to the all star break.
With 95% of all healthy pitchers, I assume about 200 innings pitched on a season. For a replacement level pitcher, the 100 innings may be on the low side since you may be able to stream pitchers and maximize innings.
An owner should be able to cobble together 100 IP before the All-Star break.
And it seems like Fernandez may only pitch 1/3 of the season in the majors so I’d go with 60-75 innings. Another fun aspect is valuing him in keeper auctions where he is not already kept for 2015. I’d say the bidding will go to at least 1/3 the value of a full stud season. He won’t pitch that well in all likelihood in 2015 but that means a $12-14 NL Only salary
Yep this is a great point for spreadsheet makers everywhere. Another approach that I like is to define a $ value provided per IP for replacement level pitchers, and apply this blanket adjustment to all pitchers not projected for at least say, 180 IP.
Also, humble suggestion – write the same article about 300 PA of Bryant’s steamer projection and 300 PA of rep. lvl. third baseman
“Among the players [147], 29 (20%) failed to return to MLB competition, 19 (13%) returned only to active status (failing to appear in >= 10 games in a single season), and the remaining 99 (67%) returned to established play after surgery”
This is from the T J S article you referenced. There is ridiculous & unreasonable optimism about this procedure these days despite recent spectacular failures ( Beachy springs to mind). Even the above article puts forth an 80% success rate by including the 10% who returned but we’re ineffective.
Your spreadsheet needs to factor in the 33% chance that Jose does not return or is ineffective. There needs also to be the consideration that he may not be good this year despite his eventual return, since some of the 67% who were successful were not immediately so.
Personally, I’m going to take a pass unless he is very cheap.
What sucks is when you see the bargain value in injured players, and because other drafters don’t, you end up with 4 or 5 injured players on your roster and they all get hurt and clog up your DL slots.
I wouldn’t “mash” the Fernandez/Gonzalez stats in equal amounts. I’d take all 100 of Fernandez’s assumed IP and mash those with about 100 innings of Gonzalez. You’re not going to use all 135 of Gonzalez’s innings in this scenario since, presumably, you only wanted 200 IP out of this slot and every other pitcher you own is above replacement value.
He did do that. If you look at the spreadsheet at the bottom, he adjusted Gonzalez down to 100 IP and used that.
Fernandez will make a much bigger impact in H2H where he can give a team a nice boost in the stretch run and fantasy playoffs.
In roto, 75-100 innings isnt going to make a huge difference.
With the article you linked to, I think a problem in the year-to-year stats changes could be that they’re unadjusted for run environment. As the graph near the start of the article shows, a vast majority of Tommy John surgeries have occured within the last decade or so, and since offence has decreased so much over the past five years, many pitchers in teh dataset would’ve returned to a lower run environment than they’d been injured in, artificially improving their post-surgery numbers.
