ATLANTA -- Left-hander Sean Gilmartin, the Braves' first-round pick in the 2011 First-Year Player Draft, was promoted to Triple-A Gwinnett on Friday.

In his first full professional season, Gilmartin has made 20 starts at Double-A Mississippi. In 119 1/3 innings, he has struck out 86 and walked 26. Gilmartin was also named to the Southern League All-Star team but did not pitch in the game.

Braves manager Fredi Gonzalez said he was excited to see how Gilmartin responded to the promotion.

"He's a guy that has pitched pretty good in Double-A," Gonzalez said. "And why not? Put him out there in Triple-A and see what he can do."

Ranked this season by MLB.com as the Braves' No. 5 prospect, Gilmartin was the 28th overall pick in last year's Draft after an All-American junior season at Florida State.

The date of Gilmartin's Triple-A debut has not yet been announced. He last pitched Tuesday, putting him in line for a start Sunday at Charlotte.

Braves sign righty Batista to Minor League deal

ATLANTA -- The Braves signed right-hander Miguel Batista to a Minor League contract, manager Fredi Gonzalez said Friday. Gonzalez said Batista would be assigned to Triple-A Gwinnett, but he wasn't sure if the 41-year-old would join the rotation or the bullpen.

Batista pitched in the Mets' bullpen this season but has also made 248 career starts. He was designated for assignment Sunday by the Mets and released Thursday. Batista is 1-3 with a 4.82 ERA this season and has pitched 46 2/3 innings, most recently in a spot start Saturday against the Dodgers.

Gonzalez said Batista will bolster the Braves in Triple-A.

"He'll add some depth, just in case," Gonzalez said. "That's a good, experienced arm that doesn't really cost you anything."

Also joining Gwinnett will be veteran right-hander Peter Moylan, who is working his way back from surgery last September to repair a torn right rotator cuff.

Moylan has pitched 10 innings at three levels of the Minor Leagues so far this season. Gonzalez isn't sure how much time Moylan would need in Triple-A before he could rejoin the Braves, but the manager said he would be a boost to the Braves' bullpen.

"If he's pitching like he was before he got hurt, he could really, really help us," Gonzalez said. "But I don't know where he's at, to tell you the truth."
