Angels place LHP Thatcher (ankle) on disabled list
Thatcher was hurt fielding a bunt in Saturday night's 10-3 loss at Tampa Bay.
In a series of moves Sunday, Los Angeles also optioned left-hander Michael Roth to Double-A Arkansas and recalled right-hander Cam Bedrosian from the Texas League club. Right-hander Fernando Salas was recalled from Triple-A Salt Lake.
Roth, recalled Friday night from Arkansas, pitched the final 4 2/3 innings Saturday night after Thatcher left in the fourth.
