Brewers place Corey Knebel on Injured List

Craig Counsell says it’s not the arm that’s been ailing Knebel, but his hamstring

Corey Knebel hasn’t looked quite right for most of this season as he tries to work his way back from Tommy John surgery, and now we may know why.

Knebel is landing on the Injured List with a strained hamstring that, according to Adam McCalvy, Craig Counsell says may have led to some bad habits on the mound — or vice versa.

Mark Mathias will be returning to the big league roster to take his spot.

Knebel’s had a rough go of it in his first 9 games back from surgery. While he’s struck out 7 in 6.2 innings, his velocity has been down, and he’s been getting hit around. He’s allowed 7 runs on 11 hits over those 6.2 innings, including 4 home runs. He’s only averaging about 94 mph on his fastball, down from an average of 97 pre-surgery. He’s also seen his average velocity drop on his curveball by nearly 4 mph, down to 78.4 — which wouldn’t be a huge deal if he wasn’t leaving it in the zone so much.

Once he’s able to pitch, he’ll likely be given plenty of time to figure out whatever’s been ailing him in Appleton. At this point, a stay on the Injured List and a rehab assigment may keep him off the big league roster for much of the remainer of the season.

Mathias was sent back to the Alternate Training Site in Appleton earlier this month after going 5-for-16 — all singles with no walks — during his first bit of playing time. With Ben Gamel struggling, he may see some more time in the corner outfield spots.
