Astros acquire LeBlanc; Peacock optioned
Veteran lefty claimed off waivers from Marlins, will join Houston on Sunday

KANSAS CITY -- In an effort to upgrade their bullpen, the Astros on Saturday claimed left-hander Wade LeBlanc off waivers from the Miami Marlins. LeBlanc, 28, will join the club on Sunday in Kansas City.
To make room on the roster, Houston optioned right-hander Brad Peacock to Triple-A Oklahoma City following Saturday's 7-2 loss, where he will be groomed as a starter.
LeBlanc went 1-5 with a 5.18 ERA for the Marlins this season. He appeared in 13 games and made seven starts. Over 48 2/3 innings, LeBlanc struck out 31 and walked 15. He was 2-5 for Miami with a 3.67 ERA in 2012.
From 2008-11, LeBlanc pitched for the Padres and that was when he caught the eye of Astros manager Bo Porter. LeBlanc was 8-12 for San Diego with a 4.25 ERA over 146 innings in 2010.
"I saw him and liked him when he was in San Diego," Porter said. "He has been a starter and a long reliever. He's got a really good changeup and he's another guy to add to the mix in that long relief bullpen role."
Peacock was 1-3 with an 8.07 ERA, but performed well in long relief on Saturday before getting the news after that he was headed for Oklahoma City. Peacock worked 3 1/3 innings and allowed two hits and one run.
"All I care about is that I left a good impression before I left," Peacock said. "They want me to be a starter, so I'll be starting in OKC. That's my ultimate goal, to be a starter up here."
Barnes exits with tightness in left hamstring
KANSAS CITY -- Astros outfielder Brandon Barnes left Saturday's 7-2 loss to the Royals with tightness in his left hamstring.
Barnes, who started in center field, did not come out for the bottom of the sixth. Right fielder Trevor Crowe moved to center and Jimmy Paredes entered the game in right.
Barnes had doubled and scored in the top of the sixth. But Barnes said after the game that he tweaked the hamstring in the first inning, when he bobbled David Lough's single to center and was charged with an error.
"It's just a little tight," Barnes said. "It wouldn't loosen up throughout the game."
Barnes said he thinks he'll be ready to go for Sunday's series finale.
