Gio was a 1st Round supplemental pick for the Chicago White Sox in 2004 but was traded around as a top prospect before finally breaking into the Majors. He was sent from the White Sox to the Phillies, back to the White Sox, and eventually scooped up by Oakland's Billy Beane in 2008 where he would finally make an MLB appearance.
Gio had a tough rookie year and in his first 30 appearances between '08 and '09 he had given up 92 runs in only 132 innings for an abysmal ERA. However 2010 led to a breakthrough and batters were held to a .229 average and in 33 starts Gio held a 3.23 ERA with a 15-9 record.
Building off his success last season Gio has made 2011 a strong year for him so far. In 12 starts despite the slumping A's offense he has a 5-4 record with an outstanding 2.62 ERA despite having 33 Walks due to a .233 average hitters have against him. Who knows with the way the A's offense has been, no dominant closer, and 4 other starters on the DL Gio's first half may make him the A's lone (and league required) representative to the All-Star game.
