Brewers' Aaron Ashby likely out multiple months with shoulder injury

The Brewers anticipate that left-hander Aaron Ashby will miss “a couple of months” due to inflammation in his throwing shoulder, manager Craig Counsell told reporters this afternoon (relayed by Adam McCalvy of MLB.com). The skipper said Ashby has felt pain during his throwing session and will have to be shut down entirely for some time (via Todd Rosiak of the Milwaukee Journal-Sentinel).

Milwaukee leadership had already suggested last week the southpaw wouldn’t be ready for Opening Day due to shoulder fatigue. The inflammation and complete shutdown represents a much more significant development than the Brewers had previously indicated. It’s not a complete surprise but frustrating news for the highly-touted young pitcher.

Ashby also missed time last season, logging injured list stints due to inflammation in both his elbow and shoulder. The latter issue cost him a month between late August and September, lingered into the offseason, and continues to pose a problem. His return timeline still seems to lack much certainty, though it looks as if he could be out of action for an extended chunk of the season’s first half.

The 24-year-old is a former top prospect. He’s only managed a 4.47 ERA in 139 career big league innings thus far, though he’s shown an enviable combination of bat-missing and ground-ball propensities. Ashby struck out 26.5% of batters faced in his 107 1/3 frames last season. He paired that with a massive 56.7% grounder percentage. Rays ace Shane McClanahan was the only other pitcher (minimum 100 innings) to strike out at least a quarter of opponents while keeping the ball on the ground over half the time a batter does make contact. That highlights why evaluators have been optimistic about Ashby’s upside.

Milwaukee clearly values Ashby as a long-term contributor. The Brew Crew signed him to a $20.5M guarantee last summer, adding a pair of club options to extend their window of control by two seasons. He only appeared in eight games after signing that deal before injuries intervened. There’s obviously plenty of time for Ashby to get healthy and become the caliber of pitcher Milwaukee has envisioned, though that’ll be on hold as they try to sort out his shoulder issues.

Even in his absence, the Brewers have a strong starting staff. The trio of Corbin Burnes, Brandon Woodruff and Freddy Peralta can rival any other club’s top three. Eric Lauer is a solid back-of-the-rotation arm, while Milwaukee reunited with Wade Miley on a one-year free agent deal. Ground-ball specialist Adrian Houser is on hand as the #6 option and would figure to start the season in long relief if the rest of the group stays healthy. There was some speculation the Brewers could put Houser on the trade block immediately after they signed Miley. Ashby’s longer-term health uncertainty seems to diminish that possibility.
