Milwaukee Brewers manager Craig Counsell said relief pitcher Corey Knebel (hamstring) will be out "a minimum of six weeks."
Knebel suffered a strained hamstring on Thursday while delivering a pitch, immediately falling to the ground in pain. He was unable to put any weight on his left leg afterwards, so it isn't surprising that he will be sidelined for a while. Counsell indicated that the Brewers will go with a closer-by-committee while Knebel is out. Jacob Barnes, Josh Hader, and Matt Albers are presumably the top candidates.
Knebel had a breakout year in 2017, posting a 1.78 ERA and 1.16 WHIP over 76 innings while compiling 126 strikeouts and 39 saves.
