Heading into the 2011 MLB draft, Cole, Bauer, and Danny Hultzen who was also a college pitcher, were seen as among the best available talents in the draft. The Pittsburgh Pirates selected Cole with the first overall selection. He signed a minor league contract with an $8 million signing bonus, the highest signing bonus ever offered to a rookie, 15 minutes before the signing deadline on August 15, 2011. Though he signed too late to pitch in the 2011 minor league season, he pitched for the Mesa Solar Sox of the Arizona Fall League (AFL). He recorded 16 strikeouts in 15 innings pitched for the Solar Sox and had a 3.00 earned run average (ERA) and a 0.93 walks plus hits per inning pitched ratio (WHIP). He was selected to start the AFL Rising Stars game in November 2011.
