MLB Season In Review: Oakland A’s Pitchers

By Tommy Rancel //

Biggest Surprise: Trevor Cahill

After going 10-13 with a 4.63 ERA in 32 starts as a rookie, Cahill has enjoyed an All-Star season in 2010. The 22-year-old is 17-8 with a 3.08 ERA in 27 starts. On the surface, Cahill seems like an emerging ace, but we’ll see if he can repeat his performance. More on that later…

Biggest Bust: Ben Sheets

The A’s made an unusual splash on the open market this season when they signed Ben Sheets to a one-year, $10 million deal. Sheets missed all of 2009, but when healthy is a legitimate ace. The gamble for Oakland was him staying healthy. Unfortunately for both sides, Sheets would last just 20 starts before needing major arm surgery. Not only did the surgery wipe out the rest of 2010, but most likely all of 2011 as well. Even before the surgery, the righty was just 4-9 with a 4.53 ERA.

2011 Keeper Alert: Gio Gonzalez

While Cahill has grabbed most of the attention, Gio Gonzalez might be the most talented young arm in the A’s rotation. At 14-9 with a 3.35 ERA, Gonzalez is finally living up to the hype of a top prospect. He has an above-average strikeout rate (7.57 K/9 IP), but walks are still an issue (4.04 BB/9 IP). He’s young, he’s talented, his numbers don’t suggest much of a fluke, and he’s left-handed; a keeper.

2011 Regression Alert: Trevor Cahill

As mentioned, Cahill has really good traditional stats, but a quick check of his peripherals show he has not been as impressive as those numbers suggest. His 5.31 K/9 IP is poor and his 2.89 BB/9 is acceptable, but only with a higher strikeout rate. In addition to the mediocre control rates, his .237 batting average on balls in play (BABIP) is not likely to be repeated again (league average is typically around .300). Cahill is a fine young pitcher with a terrific groundball rate (55.7% ranks among the league leaders) and plenty of room to improve. But buyers beware next season – his ERA’s likely to rise, and 17 or more wins might be a reach.
