Mat Latos and Great American Ballpark

After a scare to start his 2011 season—a trip to the DL for shoulder bursitis—Mat Latos was able to notch his second straight season of 30 starts. He has topped 180 innings in both seasons and has established himself as one of the best young pitchers in baseball. Pitching his first two seasons in San Diego has labeled some of his ability as manufactured by PETCO Park, but his ability to strike out hitters and limit his walks look like something he could do anywhere.

That idea will be put to the test afetr his move to Cincinnati this offseason. In San Diego, Latos could get away with some mistakes on account of a home park that decreased home runs 41 percent against left handers, according to In Cincinnati he’ll have to deal with a park that inflates home runs 20 percent for left-handed hitters and 33 percent for right handers. His career HR/FB has been abnormally low in San Diego at 8 percent and should increase at least to a league average 11 percent.

Will all this change affect his ability to be an effective pitcher and lead the Reds pitching staff? I’m sure it will, but that doesn’t mean Latos won’t be an elite pitcher. The past two seasons, Latos has had one of the best K/BB rates in baseball. He ranks 15th during that time with a K/BB of 3.34. That is a welcome addition to Cincinnati, where only two other pitchers have posted a K/BB over three in the past 11 seasons. Aaron Harang and Mike Leake are the only ones in the 21st century to do that in a Reds uniform.

Latos is not a groundball pitcher, but that’s not to say he is a flyball pitcher either. He is fairly neutral pitcher with a 1.03 GB/FB rate. This change in stadium along with giving up 200 fly balls each year should result in Latos giving up six extra home runs if he has a league average HR/FB in Great American Ballpark. That is going to increase his ERA by about 0.4 runs. This is represented by xFIP and SIERA, which are 3.51 and 3.48 respectively, while his FIP stands at 3.28.

All this assumption and projection would assume that Latos is going to stay neutral and experience a similar output in 2012. His ability to control walks at Double-A speaks of someone who could still get better and walk fewer hitters in 2012.

Velocity concerns

In 2010, Latos displayed a 94 mph fastball, but in 2011 his velocity averaged only 93. Only a small change, but we know that these small changes can be damaging as well as trouble in the future. While looking at Latos’ PITCHf/x new player cards at I noticed a more troublesome trend than his velocity.

Latos’ horizontal release point

As you can see above, Latos’ release point has changed each season. The good news is his vertical has not changed significantly, but the question is why the large year-to-year change in his release point that is closer and closer to his body. Maybe he is simply standing further to the first base side of the mound. Another possibility is that the Padres attempted to change his delivery to keep him healthier. Both those options are better than the last, which says he is compensating for any pain in his arm. Since this doesn’t involve vertical drop, I don’t think this is the case, but we shouldn’t rule anything out.


             W    L     IP    ERA    WAR
Pecota       12   11   186   3.69    3.7(WARP)
Oliver       14   8    210   3.25    5.0

That type of season projected by Oliver would make Latos one of the great pitchers in Reds history. Only four Cincinnati pitchers ever have totaled an fWAR greater than 5.0. That list includes Harang, Mario Soto, Jose Rijo and Danny Jackson.

Latos helps make the Reds a contender in the NL Central and at 24 years old with only two years in the majors, he is ready to help them for awhile. There is some trepidation in moving any pitcher out of PETCO Park and into any other stadium, but Latos has the skill and, the Reds hope, the health to overcome the change and dominate in Cincinnati.

    While his HR/FB rate was 8% at home over his career his HR/FB rate away was better away from PETCO in ‘11 as well as ‘10 at 6.7% and 7.7% respectively.  GABP is clearly a less favorable home, but I’m looking to draft him if managers discount him too much.

    In 2011 the MLB average HR/FB was actually only 9.7% and it was just 9.4% in 2010.  It was 10.1% in both 2008 and 2009, but dipped under 10% again in 2007.  Before that, it was always over 10%, but has only cracked 11% once for the years fangraphs has the batted ball data for—way back in 2003 when it was 11.2%. 

    FWIW, the rate for Reds’ SP as a group (remember, this includes all games, both road and in GABP) has tended to range from the high 9% range to the low 12% range, and has been 11.6% in total from 2007-2011, so expecting a rate around 11% and ~6 extra HR for Latos is pretty reasonable.  That should put his projected ERA in the 3.50-3.70 range assuming everything else stays in line with the last couple years (including maintaining his career .275 BABIP).

    I notice you didn’t mention the mental aspect of Latos’ makeup. He wasn’t drafted as high as he expected, despite his five pitch talent because, as he admitted, in high school he was a jerk. The Padres drafted him as a draft-and-follow for that reason.

    He’s come a long way since he was drafted, but it’s now not maturity but developing the mental discipline required of an ace. I would have liked to hear what leaving the Petco cocoon and joining a club that will be in the thick of a division race might do for his mental discipline. I personally feel it’ll be the best thing for his development into an even better pitcher than he’s shown.
