Nats to put Strasburg on innings limit

Nationals right-hander Stephen Strasburg will be on an innings limit next season as he continues his comeback from reconstructive surgery on his pitching elbow.

General manager Mike Rizzo says Sunday that he already has ”semi-calculated” the number of innings Strasburg will be allowed to throw in 2012.

Strasburg had his ligament-replacement operation in September 2010, then returned to the majors this September. He’ll make the fifth start of his comeback Wednesday at the Marlins on the last day of the regular season.

Nationals righty Jordan Zimmermann, who had the same surgery as Strasburg in August 2009, was shut down this season after reaching his innings limit. He threw 161 1-3 innings, making his last start on Aug. 28.
