Baseball’s supposed to be a simple game and it is in theory. But the deeper a person digs, the more complex it gets. ERA estimators like FIP, xFIP, kwERA, and SIERA came along to help explain the limits of ERA. The main issue with each metric is how to deal with batted ball data. More specifically, they fail at it. I tried to answer the batted data question with pERA but it only explained some of the differences. Even with all those attempts to fill in the missing data, some differences haven’t been explained. Today, I am going to fill in on missing gap while examining a pitcher’s breaking ball zone rate.

Today’s study will be sponsored by Michael Pineda and Robbie Ray. Each pitcher has posted good strikeout and walk numbers which historically has pointed to good ERA’s. Instead, they get hit around and their ERA’s are quite a bit higher than their estimators. Here are the career stats for the pair.

Note: I am not covering the possible Davis for Soler trade between the Royals and Cubs because it is still in the possible stage. Once the medicals get cleared up, someone at RotoGraphs will cover it.

Colorado Rockies sign Ian Desmond

This move is a little confusing in a vacuum. The only position Desmond slots in defensively for the Rockies is first base. The problem is that his offense output doesn’t match up with other first basemen (Desmond’s projected wOBA before the move (.312) would put him around 45th overall at first). I don’t think the Rockies are done making moves, though, so I expect Desmond to probably be on the outfield depth chart soon.

No matter his position, Desmond’s value just skyrocketed. With half his games in Colorado, his batting average will jump along with his RBI and Runs chances. It will be interesting to see where he slots into the lineup which could affect his Run-RBI mix.

Owners need to spend a little time making sure they have a good handle on his value. Don’t wing his valuation. Have a decent idea where his value slots in with your league settings. He could get overvalued if his batting average doesn’t soar like people expect, but I think he will likely be undervalued as his power and speed production could make him similar to Charlie Blackmon.

Note: The great and powerful Paul Sporer will examine the Mark Melancon, Rich Hill, and Steve Pearce moves in the next day or so. I am just catching up on the moves from the weekend.

Yankees signed Matt Holliday

In a vacuum, this signing makes sense for the Yankees and Holliday. The Yankees needed a designated hitter and Holliday needed to transition away from playing the outfield. As the Yankees roster stands at this moment, Tyler Austin and Gregory Bird will be competing for time at first base and the outfield is Brett Gardner, Jacoby Ellsbury, and Aaron Judge. All the veterans have a role and everyone should be content.

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.
