Jeffress (shoulder) threw a bullpen session Wednesday without issue, and is scheduled to throw off a mound again Saturday, Adam McCalvy of MLB.com reports. The Brewers placed him on the 10-day injured list Thursday.
Manager Craig Counsell didn't go into detail about Wednesday's session, but with Jeffress scheduled to throw again in just a couple days, it must have gone without a hitch. Jeffress will still be unavailable to begin the season, but since he's throwing again without issue, he should be on track to make his 2019 debut at some point in April. For most of the offseason, Jeffress was expected to work in a setup role (along with Josh Hader) in front of Corey Knebel, but Knebel is expected to miss some time -- possibly the entire season -- with an elbow injury. Knebel's likely long-term absence means that Jeffress and Hader figure to share the ninth-inning duties in some fashion when Jeffress is ready to go.
