The Red Sox placed Suarez on the 15-day injured list Thursday with a left groin strain.
Suarez exited his previous start Sunday against the Angels due to what the Red Sox referred to as left adductor tightness, but a subsequent MRI revealed a groin strain, which will keep the southpaw out through the All-Star break and prevent him from pitching in the Midsummer Classic. Suarez earned his second All-Star nod after compiling a 3.15 ERA, 1.16 WHIP and 97:26 K:BB across 91.1 innings in his first season with Boston. His turn in the rotation had been set to come up Saturday at Citi Field, and the Red Sox are now likely to call up Brayan Bello from Triple-A Worcester to either start or pitch in bulk relief in that game against the Mets.
