Matt Garza is expected to undergo an MRI on his strained left lat muscle within the next couple of days.
The Cubs are calling the strain "minor" and Garza told reporters on Sunday that it "shouldn't be a big thing." But there's no harm in ruling out any potential structural damage. Garza, 29, posted a 3.91 ERA, 1.18 WHIP and 96/32 K/BB ratio across 103 2/3 innings last season. He's likely to be traded at some point this summer.
