The two baseball teams in Chicago seem to be trending in opposite directions, but the Cubs and White Sox do share one thing in common: they are being afflicted by the injury bug.

For the Cubs, they had a player go on the disabled list Friday, as Tommy La Stella was placed on the 15-day DL with a strained right hamstring. To compensate for his absence, the Cubs traded for outfielder Chris Coghlan on Thursday, and he was called up to the 25-man big-league roster to replace La Stella.

The Cubs will also be without Anthony Rizzo for a short time, as the first baseman is dealing with a back issue. He has not been placed on the disabled list as of yet, but for Friday he’ll be replaced in the lineup by Javier Baez at first base.

The White Sox have been going through plenty of roster turnover the last few days, with Mat Latos and Jimmy Rollins both getting designated for assignment, but the team will also have to deal with being short-handed in center field, as Austin Jackson was placed on the 15-day disabled list. Originally hobbled by turf toe, Jackson also was dealing with a torn meniscus in his knee, and he underwent surgery to repair the injury.

To replace Jackson, the White Sox have brought Jason Coats back onto their big league roster.

The Cubs will be looking to take advantage of a weak opponent on their schedule this weekend as they take on the Atlanta Braves for the final time at Turner Field, while the White Sox will welcome the scuffling Kansas City Royals to U.S. Cellular Field for a weekend series.
