Pirates' Andy LaRoche out with knee injury
• Pirates third baseman Andy LaRoche wasn't in the lineup Friday against the Houston Astros. LaRoche's right knee was bruised and stiff after being hit by a pitch from the New York Mets' Mike Pelfrey on Thursday. "Hopefully, it's just a one-day thing," Pirates manager John Russell said. LaRoche took a few swings in the cage before last night's game and was available to pinch hit.
• Pirates shortstop Jack Wilson was back in the lineup last night after missing a game because of a stomach virus.
• According to the Elias Sports Bureau, Pirates center fielder Andrew McCutchen is the second player since 1947 to record a stolen base and three runs scored in his major-league debut. Cleveland's Dave Roberts did it in 1999.
• The Pirates signed minor-league free-agent right-hander Mike Koplove and assigned him to Triple-A Indianapolis. Lefty Corey Hamman was sent down to Double-A Altoona. Koplove, 32, went 1-3 with a 1.16 ERA in 21 relief outings this season with Lehigh Valley, Philadelphia's Triple-A affiliate. He hasn't pitched in the majors since 2007, when he had a 6.00 ERA in five relief outings for Cleveland.
• To clear roster space at Altoona for Gorkys Hernandez, outfielder James Boone was unconditionally released. Boone, 26, was the Pirates' third-round pick in 2005. Hernandez was one of three players acquired from Atlanta earlier this week in the Nate McLouth trade.
