Lands on IL with elbow strain
The Red Sox placed Guerrero on the 15-day injured list Saturday due to a right elbow strain.
Analysis
Guerrero allowed four runs on four hits and three walks while striking out one batter over his last two outings, and his elbow injury may have played a part in his recent poor performance. He's eligible to be reinstated July 13, but a strained elbow to the throwing arm typically results in a longer-than-minimum stint on the IL. To bolster their bullpen, the Red Sox reinstated Chris Murphy (elbow) from the 60-day IL in a corresponding move.
