TigsStats: 2009 GCL Tigers Pitchers

The TigsStats series now resumes in 2010 with a look back at the organization's minor league clubs and their performances. Continuing on with the rookie level clubs, we evaluate the GCL Tigers' pitchers.

Guichardo led the way on the mound for the GCL Tigers, but while his ERA was absolutely dominating, it's pretty likely Guichardo was the beneficiary of a fortunate campaign. Despite an ERA under two, his FIP was actually in the mid 4's, and his BABIP was an incredibly unrealistic .210. Couple that with a K:BB ratio well under two (and a high walk ratio at that), and it seems likely that Rayni is in for an adjustment in 2010.

Coming in with more experience, Samuels was expected to be successful, and that he was. His FIP was still notably higher than his ERA, but a mid 3's line is still solid. Samuels struck out nearly three times as many as he walked, and did a respectable job of keeping the ball on the ground. Samuels however had the advantage of being older than most of his competition, and will have to prove he can keep up his success against more seasoned hitters.

Lebron has become known as a player more about projection than production right now, but he certainly didn't underperform for the rookie club in '09. Lebron struck out nearly ten batters every nine innings, had an FIP that mirrored his ERA, and limited his home run numbers despite higher fly ball rates. Lebron obviously still needs to work on limiting his incredibly high walk rate, but Lebron has the arsenal to remain strong while limiting those.

The recently drafted Soto had a very strong debut pro season for the Tigers, though it wasn't quite as good as his ERA indicates. His FIP was a full two points higher than his ERA, but at just above three, it still shows a very productive year. Soto probably got a bit of good fortune in the BABIP department, but he kept the ball on the ground which always helps. Soto's K:BB was good but not great and his walk rate will have to come down in future years.

Despite a high ERA, Diaz actually put together a very strong season. His ERA was over five yet his FIP was under three, so he clearly pitched better than his ERA indicated. His K:BB ratio was excellent, and he did a great job of keeping the ball on the ground. Diaz's ERA may be a concern because of the obvious, but his real 2009 was much better, and he could be in line for a strong 2010.

As we reach players that had less than 30 innings, the variability amongst the pitchers' numbers will get higher, so it will be tougher to infer as much from the pitcher's stats. In this case, Siso had a respectable K:BB ratio, but was helped by a low BABIP, and allowed a lot of fly balls, which could be a problem down the road for him.

The other Diaz also put together a solid 2009 campaign, with an FIP reasonably close to his ERA. Diaz's biggest concern is of course his very high walk rate, which as good his strikeout rate is, isn't good enough to balance that out. Diaz also has a high fly ball rate that resulted in an elevated (for the GCL) home run rate.

Nunez had a very rough campaign in 2009, and unlike some of the others, Nunez's peripheral stats don't tell a different story. His FIP is close to his elevated ERA, his walk rate is high and his strikeout rate doesn't come close to balancing it. However, the biggest concern is the high home run rate, averaging 1.3 homers per nine innings. If he can't limit the long ball in future seasons, he's going to struggle to lower the runs he allows.

Richard Zumaya had one of the largest outlier stats of the 2009 season, with a BABIP not just approaching .400, but getting closer to .500. Zumaya struck out almost 11 batters per nine innings, while only walking three. There has been some questioning of Zumaya and whether or not he'll be able to follow in his big brother's footsteps, and those questions will still remain until he can be effective in keeping runners from crossing the plate, but his 2009 was quite a nice showing.

Mercedes excelled at keeping players off the base paths, and did an even better job at keeping balls in play on the ground, which will help him excel as he moves up with nearly 70% of the balls in play on the ground. Mercedes however still struggled with his walk rate, and probably had a lower ERA thanks to help than solely his pitching. Mercedes however excelled as the team's closer and will likely continue in that role as long as he's effective.
