Arizona Diamondbacks outfielder David Peralta was placed (right AC joint inflammation) on the 10-Day Injured List retroactive to May 22.
Peralta has been dealing with this injury for a while so he will need a stint on the Injured List to fully recover. The Diamondbacks have replaced Peralta's roster spot with utility-man Tim Locastro.
In 191 at-bats this season, Peralta is hitting .309 with 7 home runs and 30 RBI.
