Jesse Hahn should not be a starting pitcher!

Billy Beane has great success in finding under-valued talent. However, why is Jesse Hahn being used as a starting pitcher? Shown below are his pitching data, including college, the minors and majors.


What we see is that Hahn has been a starter for almost his entire career. However, his career high for innings pitched in 8 years was last year, totaling 115 innings. Do the A’s intend to get 150 innings out of Hahn as their #5 starter? That seems to be a best case scenario. Including college, Hahn has averaged 57 innings per year, including missing all of 2011. Take out 2011 and his yearly average is still only 66.3 innings! In a worst case scenario, Hahn may not last the full year. Based on these data, Hahn may be best suited for a relief role.

Kyle Schwarber may be the next big-time Cubs prospect to be promoted

Update: Schwarber is still doing well at AA. Through 31 games, he has 7 HR and 20 RBI’s, and is also showing great plate discipline, with 22 BBs. However, he probably shouldn’t be promoted as a catcher-he has only stopped 7 base runners from stealing, while 34 have succeeded!

4/23/2015 Although he only has 4 RBI’s through 10 games in AA, Kyle Schwarber is playing well (.345/.513/1.030), and in my opinion will be promoted to AAA soon, and to MLB sometime this year. Here’s his MILB page:

Steven Souza: Terrible Hitter or Great?

Involved in the Will Myers trade is Steven Souza. His 2014 stats at AAA, .350/.432/1.032, 75 RBI’s in 90 games are impressive. But, what I’d like to point out is that Souza was a terrible hitter from 2007-2011. In 444 games during that time, Souza hit .226 (347 hits in 1538 ABs), with walks and strike outs once for every 8.7 and 3.9 ABs, respectively. In contrast, from 2012-2014, in 278 games Souza hit .314, an almost unheard of 9 percent improvement in batting average. How did Souza do this? At least two factors are involved. Souza was able to strike out less, once every 4.9 ABs, while maintaining the same walk rate (1/8.8 ABs), thereby indicating that a better ability to make contact. Second, Souza played 3B/SS from 2007-2010, making lots of errors-92 in 249 games, which translates into 60 errors for a 162 game season! From 2012-2014, Souza played the outfield extensively, and, not having to think about errors in the infield may be a second reason for Souza’s improved success at the plate.
