23-year old righty starting pitcher Jarrod Parker came over in the big Trevor Cahill deal with the D-Backs last winter. He wound up finishing in 5th place in the A.L. Rookie of the Year voting in 2012. Parker pitched in 29 games (all starts) for the A’s last year and he was 13-8 with a 3.47 ERA and a 1.26 WHIP. Parker gave up 166 hits and he walked 63 batters while whiffing 140 of them in 181 1/3 innings last year. Those are some pretty impressive numbers and he is just going to get better.
