Hyun Soo Kim signed with the Orioles before last season on a two-year deal. He struggled mightily in spring training and because of the nature of his contract, the major league team was forced to roster him. After just 17 plate appearances in April, he became a decent semi-regular in the lineup. The left-handed hitter got on the strong side of a platoon with Joey Rickard or Nolan Reimold being the other half.

He became a decent fantasy option in daily transaction leagues by posting a .329/.410/.454 in until July 10th when he went on the DL with a hamstring injury. After the injury, he hit only .275/.353/.386. The second half numbers are decent numbers, but not as good as before the injury.

With the new StatCast data, I examined it to determine if there was a drop in Kim’s exit velocity around the time of the injury. Using a 10-day rolling average, the available data may not look like it but the rolling average generally stays around 7 mph of the overall average. Additionally, there was  no huge pattern change around the time of the injury.

The problem is that StatCast is not able to collect all the available data as documented at FanGraphs and The Hardball Times. The missing data is normal weak groundballs or high infield popups. I am not going to regurgitate the reasons and the exact details from the previous articles but I am going to take a step forward in accounting for the missing data.

Information is slowly coming out on the new Collective Bargaining Agreement (CBA) between the major league owners and players. Most of the news centers around the All-Star game no longer determining home field advantage or changes to draft pick compensation for free agents. All that information is useless for people playing fantasy baseball, though.

Almost all of it. Buried in all the news is that the minimum disabled list (DL) stint has gone down from 15 to 10 days according to the Associated Press.

In addition, players and management agreed the minimum stay on the disabled list will be reduced from 15 days to 10.
…
The DL change will allow teams to make quicker decisions on whether to bring up a roster replacement rather than wait to see whether the injured player would be ready to return to action in less than two weeks.

I never read or knew this change was even on the negotiating table so I haven’t had a lot of time to ponder the change. While it won’t drastically change the fantasy or real world game, I think it may add a little bit more stability to fantasy baseball. The following are some initial ideas I had after hearing the news.

I think the move will have different implications for hitters and pitchers. Let me start with the hitters.

Jose Ramirez: 2017 Projection

Jose Ramirez was an afterthought for most people coming into the 2016 season. He had struggled early in 2015 (.176/.243/.235 in the first half) and was demoted and Francisco Lindor got called up. He came back in the season’s 2nd half and has been a different hitter ever since. His second half improvement went unnoticed because of the bad first half stats bringing down his value.

I read back through news reports to see if he was dealing with an injury or a change in approach while in the minors and could not find anything. Instead, I will throw out a bunch of stats showing the change without knowing the reason. First, here is his 2015 average exit velocity from baseballsavant.com.

Before getting demoted, his average batted velocity was below league average (84.8 mph) and after coming back it hovered around league average (87.9 mph). Besides hitting the ball harder, he went to a more line drive approach with his swing.

Mariners trade Taijuan Walker and Ketel Marte to the Diamondbacks for Jean Segura, Mitch Haniger, and Zac Curtis

Let me start with the two players the Diamondbacks acquired. The move to Arizona is probably a break even move for Walker’s output. Now he is facing the pitcher twice a game instead of the DH, but instead, he has to pitch in his offensive-leaning home park and also travel to Colorado. The bigger question isn’t the small peripheral factors relating to park or league but instead figuring out his true talent level.

Walker is probably considered to be a failed prospect after being in the top-20 of several prospect lists. While he has not lived up the top prospect ranking, he is still a decent fantasy option and could be an even better one if he gets the home runs under control. Just looking at his K%-BB%, he ranks 27th overall the past two seasons (min 300 IP) with the likes of Cole Hamels, Ian Kennedy, Jose Quintana, and John Lackey.

About a week ago, I went over the stats I use when examining hitters during the offseason. Today pitchers take center stage. With Pitchf/x and now Trackman publicly available, I find it quite a bit easier to evaluate pitchers and the changes they make. For pitchers, I have one sparkling new main source and one old standby.

Pitchers are so much easier to evaluate compared to hitters. If a pitcher gains a couple ticks on his fastball, we know right away within a couple of pitches. If a hitter can no longer catch up with a 96 mph fastball, it may take a few months to know for sure and even then, we may not be sure why. Here are the tools I use to help find pitchers who have changed for the good or the bad.

Pitch Type Metrics

Ever since helping Eno dive into pitch-type metrics, I’ve determined that I will evaluate pitchers using this type of data. Even though it took a while to hammer everything out, the final results have been extremely promising. We can now determine what each small pitch change will mean for each pitcher and how pitchers can improve their results. The complete write up of the process is available, but here is a quick summary.

• The key change is to give each pitch an ERA value (pERA) based on the pitch’s swinging strike and groundball rate. All the values are based off the average values for starting pitcher. Closers will have higher grades because their stuff plays better coming out of the bullpen.
• The pitcher’s control is determined from their walk rate which is separate from the pitch grades.
• I’ve put each pitch on the 20-80 scale with 50 being average, 80 great, and 20 horrible. For starters, target pitchers with three average or better pitches. For relievers, they just need two pitches.

Miguel Sano: 2017 Projection

Trevor Plouffe has elected for free agency which means Miguel Sano is slated to be the Twins starting third baseman. Sano has positive defense metrics for third base, unlike the outfield where he has been a subpar defender. This move has really opened up the playing time Sano which will help with his uninspiring fantasy value.

Sano’s game can be summed up as “trying to hit the ball hard”. When the 23-year-old makes contact, he can really hit it hard has seen by his career 23% HR/FB rate, .240 ISO, and .354 BABIP (good for a slow guy).

The Astros have so far been the major mover this offseason. After signing Charlie Morton earlier this week, they picked up Brian McCann and Josh Reddick yesterday. The team has already remade themselves and the offseason has just started.

With the offseason just getting started, it is tough to get a good feeling on what the Astros will end up looking like going into spring training. When the offseason is nearly over, fantasy owners will need to sit down and figure how the playing time will get divided up among the players in Houston to help determine final values.

Astros sign Josh Reddick

Josh Reddick is one of those players in I hate drafting. If Reddick is an option on my draft sheet, I usually go another direction as Reddick offers little to no upside and downside. He is the safe play and for some people, the right move for them. The 30-year-old has had some up-and-down performances like the 32 home runs in 2012 or the single stolen base in 2014 but otherwise he is good for a dozen home runs and 10 steals with a .270 AVG.

Over the past four seasons, Reddick has traded off some power for a better contact rate. His strikeouts are down (20% to 13%) with his batting average being up (.226 to .281). While he has changed some, it is not enough to move his fantasy value.

Right now I am in the middle of writing preseason player profiles for several publications. Like most people, I examine a player’s stat page for most of the information. Additionally, I have access to our database and have created some cheat sheets to help with looking for possible changes in a hitter’s profile to help explain stat changes like a significant bump in home runs. Today, I’ll start with making my hitter sheet available and go over a few players with the information.

I find hitters to be the tougher than pitchers to determine if changes in production are from a new approach or from just plain luck. To help find such changes in approach, I determine changes in several metrics which would point to an overall talent adjustment. The stats I examine are:

Swing based
Pull%
GB%
Hard%

Eye base
BB%
K%

Eduardo Nunez: 2017 Projection

The 29-year-old Nunez went from being a Twins bench player to a top-40 fantasy player. Looking over his year-to-year profile he was basically the same player he’s been for his career, but he was given a full season of plate appearances for the first time in 2016. For example, his 2016 triple slash line (.288/.325/.432) is almost identical to his 2015 line (.282/.327/.431).

Two small differences, besides the playing time which was a huge difference, were important with his 2016 season. The first was an improving power profile.

I am a little worried the home runs may not be as high playing in San Francisco, but they should be in the double digits.

Positional Scarcity and Shortstops

Today at RotoGraphs, we start examining shortstops. At First Pitch Arizona, experts were stating that position scarcity is not an issue in 2017 except with catcher. Owners might think they don’t need to pay extra for filling their shortstop position and they can just get the best hitting talents. This statement is true for some leagues and for others, it is completely false. Scarcity depends entirely on each league’s individual settings. The two main factors which can make a league play differently are the required roster positions and the stats counted.

As for a position comparison, our own Ottoneu requires three middle infield spots and only two corner spots. Corner infielders are in less demand than in these leagues with three corner spots. Additionally, owners are usually complaining about the catcher options, but in my 20-team industry and local AL-only leagues, they require only one catcher. Some catcher options exist on the waiver wire. If the required number was two, catcher values would skyrocket.

The other difference is the stats counted. In normal roto leagues, stolen bases are a category and they give shortstops a huge value boost. In a linear weights league, the value of stolen bases becomes non-existent and then positional scarcity exists for shortstops.

If you want to read some detailed look at calculating position scarcity value, read the links at the beginning of this article by our own Mike Podhozer.
