Red Sox's Liam Hendriks: Side session set for Wednesday

Hendriks (elbow) will throw a bullpen session Wednesday, Jen McCaffrey of The Athletic reports.

Red Sox pitching coach Andrew Bailey said Hendriks has been throwing "half-mound" sessions, but Wednesday's activity marks the reliever's first session throwing on the top of the mound since undergoing Tommy John elbow surgery last August. If Wednesday's workout goes well, a normal progression would have Hendriks throwing two bullpen sessions per week before ramping up to face hitters.
