The Brewers recalled Junk from Triple-A Nashville on Friday.
The move corresponds with Milwaukee placing southpaw Rob Zastryzny on the 15-day injured list due to left elbow tendinitis. Junk has spent most of the season in Nashville, posting a 2.65 ERA and 1.29 WHIP across 34 innings. He's made three major-league appearances in 2024, with his last coming May 5 against the Cubs in which he allowed one run on three hits and one walk while striking out two across two frames.
