In his final regular season outing, the Newport Beach, California native went 6.0 innings to earn his 10th victory of the season as the Pirates defeated the Chicago Cubs by an 8-2 tally at Wrigley Field. With the victory, Cole became the first Pirates rookie to reach double-digit wins since Josh Fogg (12-12) in 2002. Cole allowed just two runs in the contest while striking out six, giving him 34 strikeouts in 26.0 innings over his last four starts of the season - the most by a Pirates rookie in a four-start span since Jose DeLeon fanned 38 during a four-start stretch in August 1983. Cole struck out a career high 12 batters in 6.0 innings of work in his September 19th start against the San Diego Padres at PNC Park, allowing just four hits while walking three to earn the win. The 12-strikeout performance marked only the second time since 1900 that a Bucs pitcher had fanned a dozen-or-more batters in a game in which he pitched 6.0-or-fewer innings (Oliver Perez struck out 12 Rangers in 6.0 innings on June 10, 2004). The performance came on the heels of back-to-back 7.0-inning victorious outings for the 23-year-old. On September 14th, Cole allowed just one run while striking out seven in a 2-1 win over the visiting Cubs, and on September 9th, he held the Texas Rangers scoreless while fanning nine in a 1-0 victory at Rangers Ballpark in Arlington. The first overall selection of the 2011 Draft earned a no-decision in his September 3rd outing at Milwaukee despite allowing just two earned runs in 6.0 innings of work. The start was part of a run of eight consecutive quality starts by the youngster dating back August 16th.
