The Brewers recalled Fitzpatrick from Triple-A Nashville on Friday.
Fitzpatrick has turned in a 1.13 ERA and 1.00 WHIP through 16 innings at Nashville, and he's also performed well when called upon by the Brewers, allowing just one earned run in 5.2 frames. He'll now rejoin the big-league bullpen alongside Craig Yoho to replace DL Hall (pectoral) and Jake Woodford.
