Going into spring training, the Oakland Athletics had a highly touted battle for the fifth rotation spot between Trevor Cahill, Gio Gonzalez, and Vin Mazzaro. Truth be told, I'm not sure how many people ever considered it a three-man race.
Cahill had just completed a full year at the major league level, Gonzalez has shown he has nothing left to prove in Triple-A, and all Mazzaro has done at the big league level is hurl two great scoreless starts in 2009 and then fall back to Earth... and then some... to the tune of a 5.32 ERA in 91.1 big league innings.
