Kimbrel was signed in early June, but didn't make his Cubs debut until June 27th after a minor league stint, or a late Spring Training to some. Since making his team debut, the former Atlanta Brave and Boston Red Sox World Series Champion has recorded 10 saves, despite posting a career-worst 5.68 ERA.
Contreras was placed on the injured list on Sunday, before the severity of his injury was revealed. The catcher is expected to miss four weeks with a strained right hamstring. Just like Kimbrel's, this injury also occurred on Saturday while he was running out a fly ball. An MRI revealed the Grade 2 strain, which sent him to the 10-day injured list. The 27-year-old made the All-Star team for the National League last month, and is batting .275 with 19 home runs and 57 RBIs. In his absence, Victor Caratini is expected to get a majority of the playing time behind the plate, since Chicago traded away Martin Madlonado at the Trade Deadline for outfielder Tony Kemp.
