Among five Bucs callups, Grilli set to reclaim closer role

MILWAUKEE -- The Pirates recalled another five players from the Minors on Tuesday, none of them strangers, but one of them definitely unexpected.

Reliever Jason Grilli, originally slated to follow up two appearances with Double-A Altoona with another for Indianapolis, instead was recalled from his rehab assignment and activated for the night game against the Brewers.

Among four recalled from Double-A Altoona was All-Star left-hander Jeff Locke.

Locke and Grilli will both immediately jump back on the pennant-race treadmill. Locke is scheduled to start the middle game of this weekend's series in St. Louis with the Cardinals. Grilli will pitch in a few "non-leverage outings," in manager Clint Hurdle's words, then reclaim the closer's role.

Also recalled from Altoona was pitcher Jared Hughes, outfielder Andrew Lambo and catcher Tony Sanchez.

The moves put the Pirates' active roster at 32.

Grilli started Saturday and Monday for the Curve, pitching one shutout inning on both occasions. He was due to pitch an inning out of the bullpen in the Indians' playoff game Wednesday in Durham, but he struck out the side in Monday's outing, and the staff felt no need to extend his rehab.

"In that second outing, he really ramped it up," Hurdle said. "Now with the challenge of facing Major League hitters and the adrenaline that goes with it, we'll have a much better feel [for where he's at]. Eventually, the plan is to transition him back to the closer's role."

Grilli led the National League with 30 saves when he went down with forearm tightness on July 23. In his absence, Mark Melancon has converted eight saves in nine opportunities.

"I'm not here for myself. I've said that all year," Grilli said. "I'll pitch when they give me the ball. Mark's been doing a great job. We're all in this for the same thing.

"If I want to get out big league hitters, I've got to face them," added Grilli, echoing the sentiment that there was nothing to be gained by having him follow through on that third planned rehab outing. "I think I showed my arm is where it needs to be. There was not much else to prove."

Locke -- due to toss a bullpen session prior to Tuesday night's game as a warmup to his Saturday start at Busch Stadium -- returned with the same positive outlook. He had skipped a turn and was optioned to Altoona as a roster convenience after failing to last past the fourth inning in three straight starts.

"Plan is to jump right back on, go out there, give us a chance to get on top and hold them to minimal offense," Locke said.

Worth noting

• When Stolmy Pimentel makes his Major League debut, he will become the 28th pitcher used this season by the Pirates -- a new club record. Yes, that does include Josh Harrison for his perfect one-third inning on Aug. 9, in Coors Field.

• Before Tuesday's game, Starling Marte's right hand (contusion) was heavily bandaged with an attached H-Wave generator, a modulator to reduce inflammation in joints.

• Left-hander Justin Wilson prompted some doubletakes in the clubhouse, wearing a black tee-shirt with the classic Buccaneer logo, but the word "Zombies" spelled out in the club's font where "Pirates" should have been.

• With his 10th homer in Tuesday night's game, Neil Walker became the first second baseman in club history to reach double-digit homers in four consecutive seasons. Bill Mazeroski did it for three straight, from 1960-62.

Andrew McCutchen entered Tuesday's game tied for second in the Majors (with St. Louis' Matt Carpenter ) in multihit games, at 52. Mike Trout of the Angels led with 53.

First number

166: Pirates hits in the leadoff spot this season, through 137 games, second most in the National League. Pittsburgh leadoff batters combined for 169 hits in all of last season.

Last word

"This is not a selfish move on my part. I'm not here to walk in and thump my chest and beat the door down. It isn't about any one player in this room. It's about the whole room. And I can't wait to get out there and do my thing again."
