Santana suffered a torn left Achilles tendon on the play and will miss the rest of the 2014 season, as confirmed by Orioles general manager Dan Duquette.

Santana currently has a 139-78 career record with a 3.20 ERA. The southpaw has appeared in four All-Star games and hurled the first no-hitter in New York Mets history back on June 1, 2012.
