Fitzpatrick (elbow) was shifted to the 60-day injured list Tuesday, Adam McCalvy of MLB.com reports.
Fitzpatrick was placed on the 15-day IL with a left UCL strain Saturday, and the southpaw may need to undergo Tommy John surgery. Regardless of whether surgery is necessary, the 26-year-old will now be sidelined until at least early August. The transaction clears room for outfielder Luis Lara on the 40-man roster after Milwaukee inked the 21-year-old to a fresh seven-year, $31 million contract extension Tuesday.
