Cubs' reliever Pedro Strop out 4-6 weeks with knee injury
CHICAGO (AP) Chicago Cubs reliever Pedro Strop needs arthroscopic surgery on his left knee and will be sidelined four to six weeks.
The Cubs announced Thursday that an MRI revealed a meniscus tear. Strop was injured fielding a grounder in the eighth inning of Wednesday's victory over the Los Angeles Angels. He was placed on the 15-day disabled list.
The timetable would make it possible for Strop to return before the end of the regular season and be available for the postseason.
The NL Central-leading Cubs had planned to use Strop and Hector Rondon as setup men for closer Aroldis Chapman, who was acquired last month.
The 31-year-old Strop has a 2.89 ERA in 50 games with Chicago this season.
The Cubs recalled right-hander Justin Grimm from Triple-A Iowa.
