Brewers' Corey Knebel to undergo Tommy John surgery, out for season

Milwaukee Brewers relief pitcher Corey Knebel will miss the entirety of the 2019 season due to Tommy John surgery.

What It Means:

Knebel had a UCL injury and was contemplating surgery or simply rehabilitation. He chose the former, and he'll now miss the season before he had a chance to begin. Josh Hader will now be the de facto closer.

In 55.3 innings last season, Knebel had a 3.58 ERA with 88 strikeouts, 22 walks and a 1.08 WHIP.
