(CBS) Cubs setup man Pedro Stop has a torn left meniscus that will require surgery and force him to miss four to six weeks, the team said Thursday afternoon.
That timeframe for a return in mid-to-late September means Strop would be available for the postseason should he recover as anticipated. Chicago's final regular-season game is Oct. 2, and the playoffs start a few days later.
Strop suffered the injury to his left knee in the eighth inning of Wednesday night's win against the Angels. His leg bent awkwardly as he fielded a chopper down the third-base line.
The 31-year-old Strop has a 2.89 ERA and 0.89 WHIP this season in 50 appearances. He's struck out 56 batters in 43 2/3 innings.
In his place, the Cubs will call up right-handed reliever Justin Grimm.
In other Cubs bullpen news, fellow setup man Hector Rondon plans to throw a side session Friday and believes he could be ready for game action Saturday or Sunday as he recovers from a triceps injury.
