His first three years with the Rangers were marked by injury, but he flourished as a front-line starter in 2011. In 30 starts and one relief appearance, he was 14-9 with a 3.39 ERA as the Rangers went to the World Series for the second straight season.
Harrison was even better in 2012, going 18-11 with a 3.29 ERA in 32 starts. He pitched for the American League in the All-Star Game and was the Rangers' Pitcher of the Year.
Harrison, signing a five-year contract extension, spent the next three seasons battling a congenital back condition that could not be fixed. He made nine starts in those three seasons before being traded to the Phillies on July 31, 2015, in the Cole Hamels deal as a way of balancing the financial considerations of the deal. He never pitched for the Phillies before retiring because of the back condition.
