The Brewers recalled Rea from Triple-A Nashville on Saturday.
Rea takes the place of J.B. Bukauskas on the active roster after Bukauskas was placed on the 15-day injured list with a cervical strain. Rea has been mediocre with Milwaukee this year, as seen in a 5.52 ERA over 31 innings in seven appearances (six starts), but he could be in line to make multi-inning appearances for the Brewers in this stint due to the lack of available options for the Milwaukee pitching staff due to injury.
