Red Sox's Lucas Giolito undergoing elbow surgery Tuesday

Boston Red Sox starting pitcher Lucas Giolito will undergo surgery on his right elbow Tuesday afternoon.

What It Means:

It remains to be seen if Giolito will require full Tommy John surgery, but either way, the right-hander will not pitch in the upcoming season. The injury is a significant loss for the Red Sox's rotation.

In 184.3 innings pitched last season, Giolito recorded a 4.88 ERA, 1.31 WHIP, with 204 strikeouts (25.7%), and 73 walks.
