Rosales became the first Rangers position player to pitch twice in one season. The only other non-pitcher with two pitching appearances for the Rangers is Jeff Kunkel in 1988 and '89.
"It's not what we want to do," Rangers manager Jeff Banister said. "I don't ever want to put a position player out there on the mound at any point, but there comes a time where you have to make a decision to save the rest of the bullpen."
That time certainly came Tuesday. After starter Martin Perez exited in the second inning, the Rangers used five relievers before going with Rosales for the ninth.
