PITTSBURGH -- The Pirates recalled right-hander Bryan Morris on Friday and designated pitcher Chris Leroux for assignment.

The move, adding Morris' live arm -- perhaps only temporarily -- to the bullpen, was made after Leroux's continuing struggles led to the Bucs losing confidence in him.

"It's all about performance. Everyone's gotta put something in the basket," said manager Clint Hurdle. "We didn't feel Chris was in a good enough place to do that right now. It was almost like we were pitching one [man] short."

Leroux yielded three runs on four hits and six walks in four innings this season. He posted a 5.56 ERA across five big league seasons with the Marlins and Pirates.

The Montreal native will now go through waivers, but even if he goes unclaimed, the Pirates will try to move him.

"If he clears waivers, we'll first look at opportunities to move him," Hurdle admitted.

Morris tossed three hitless innings and logged two saves for Triple-A Indianapolis. With the Pirates possibly having to make other moves to cover Sunday's start against the Reds -- a final determination has not yet been made on lefty Wandy Rodriguez, who is dealing with a left hamstring strain -- Morris' stay may be brief.

"We told Bryan it could be a while [or] it could be brief, and to just come in to compete and have fun with it," Hurdle said. "We could have another move sooner rather than later."

Morris made five appearances with Pittsburgh last season, recording a 1.80 ERA with six strikeouts in five innings. A first-round selection by the Dodgers in the 2006 First-Year Player Draft, Morris posted a 5.14 ERA in seven appearances in Spring Training.
