A tall right-hander with great mound presence, Hanson has three main pitches: a mid-90s fastball with good movement, an above-average changeup, as well as a 12-6 curveball which is his best pitch. His curveball is one of the best in the majors and frequently draws called 3rd strikes. However, Hanson has also had some control issues in the past.
Hanson was called up by the Atlanta Braves on June 3, 2009 after the team cut Tom Glavine. He made his debut on June 7, 2009 against the Milwaukee Brewers, pitching 6 innings, striking out 5, giving up 6 earned runs, 3 home runs, and receiving a no decision. He gave up two home runs to Ryan Braun, the first being the first hit allowed in Hanson’s major league career
