A look at how five other pitchers have fared after coming back from Tommy John surgery:
Surgery: September 2010
He returned for five starts in 2011. The Nationals said they would keep him under 160 innings this year and followed through, shutting down Strasburg after his Sept. 7 start. He went 15-6 with a 3.16 ERA in 1591/3 innings.
Surgery: August 2010
He returned for two relief appearances in 2011. The Braves kept him in the bullpen to start 2012 and moved him into the starting rotation July 31. He finished 10-1 with a 1.57 ERA and started Atlanta's wild-card loss to the Cardinals, registering 1441/3 innings for the year.
Surgery: February 2011
A Cy Young runner-up in 2010 to the Phillies' Roy Halladay, he missed all of 2011 but returned to his workhorse ways for the Cardinals this season, going 14-13 with a 3.94 ERA and three complete games during the regular season. He went 1-1 in the postseason, and for the year, he racked up 2132/3 innings.
Surgery: July 2011
He returned to a major-league mound with the Athletics on Aug. 21 -- only 13 months after surgery -- and made it look easy. He went 4-2 with a 2.57 ERA in six starts, then threw six shutout innings against Detroit in the Division Series. Including his minor-league rehab, he pitched 661/3 innings for the year.
Surgery: November 2006
After missing all of 2007, he opened 2008 in the Twins rotation and went 0-3 with an 11.32 ERA in his first three starts. The Twins sent him to Class AAA Rochester and after returning in August, he went 6-1 with a 2.74 ERA in 11 starts. For the year, he threw 1991/3 innings.
