The Chicago Cubs placed starting pitcher Jon Lester on the 10-day injured list with a left hamstring strain.
It's just Lester's second stint on the shelf since the 2012 season. The 35-year-old southpaw is expected to miss one or two starts. Tim Collins was called up from Triple-A Iowa in a corresponding roster move.
Lester owns a 2.57 ERA and 1.36 WHIP with 14 strikeouts and 6 walks across 14 innings in three starts this season.
