The Red Sox have placed Pomeranz on the 10-day DL with a left forearm flexor strain, Evan Drellich of CSN New England reports.
Earlier this spring, Pomeranz was experiencing triceps tightness, so it's interesting that he's sidelined with an issue in a different part of his arm, but the belief is that the Red Sox are simply using the DL to shelve Pomeranz temporarily while carrying an extra reliever or bench player. With the league-wide change to a 10-day DL, Pomeranz is still an option to start April 9 against Detroit, the first time Boston needs a fifth starter. If Pomeranz isn't ready to take the ball by that time, Kyle Kendrick is the most likely candidate to slot into the rotation in his place.
