Rays' Joe LaSorsa: Promotion official

The Rays selected LaSorsa's contract from Triple-A Durham on Sunday.

In order to clear room for LaSorsa on the 40-man roster and the 26-man active roster, the Rays designated right-hander Chris Muller for assignment and optioned right-hander Trevor Kelley to Triple-A. Over his nine outings (three starts) with Durham this season spanning 21 innings, LaSorsa pitched to a 3.86 ERA, 1.57 WHIP and 13:8 K:BB. He should work as a multi-inning option out of the bullpen while he's up with the Rays.
