Felix Heredia is a great example of why you want your kids to throw left handed. This guy has a career ERA of 4.44. The Cubs had Heredia for 3+ years. 1998-2001. His ERA was 6.17 in 48 games in 2001. At that point the Cubs had seen enough.
The Yankees acquired Heredia last year from the Reds. They made the mistake of being impressed by 12 games of decent relief (1.20 ERA, 15 IP, 5 BB, 4 SO). This year Felix is back to his old self: 47 G, 1-1 W/L, 38.2 IP, 44 H, 28 R, 27 ER, 20 BB, 25 SO, 6.28 ERA)
If Heredia pitches in any critical spot, Joe Torre is crazy!
