According to Steve Gilbert of MLB.com, the Arizona Diamondbacks have acquired right-handed pitcher Carlos Rosa from the Royals in exchange for Minor League shortstop Rey Navarro.

“We’re excited to get him because he’s another guy that has some upside to potentially land in our bullpen,” D-backs manager A.J. Hinch said. “We’ll see what he looks like in Triple-A before we give him an opportunity up here if he earns it.”

Rosa was 2-1 with a 3.65 ERA in six games for Triple-A Omaha this season. He was with the Major League club for 9 career games in 2008 and 2009 and posted a 3.21 ERA in 14 big league innings.

Navarro was hitting .241 for Class A Visalia.
