Houser (abdomen) is scheduled to throw live batting practice Monday, Tom Haudricourt of the Milwaukee Journal Sentinel reports.
If the scheduled session goes well, it's possible Houser pitches in an "A" game before he's sent back down to the minors. The 25-year-old returned in 2017 following recovery from Tommy John surgery in 2016 and had his start to this year's camp delayed by an appendectomy several weeks ago, but he's hopeful to be back in the majors as a reliever this season.
