Baseball-Major League Baseball roundup

May 29 (The Sports Xchange) - Houston Astros right-hander Scott Feldman underwent surgery to repair a torn medial meniscus in his right knee and likely will be out for four to six weeks, the team announced Friday. The Astros placed Feldman on the 15-day disabled list retroactive to May 27 and called up right-hander Michael Feliz from Double-A Corpus Christi to replace him on the roster. Feliz, who pitched one game in Double-A after being starting the season in high-Class A, will give the Astros another arm in the bullpen. Brett Oberholtzer is expected to take Feldman's spot in the rotation. Feldman, 32, suffered the injury while fielding a ball during his last outing. He has started 10 games this season with a 4-4 record and a 4.80 ERA. --- The Philadelphia Phillies designated outfielder Grady Sizemore for assignment to make room on the roster for outfielder Cody Asche. The Phillies re-signed Sizemore before this season to a $2 million contract, but he was batting .245 with no homers and six RBIs in 39 games this year. The 32-year-old former All-Star played in 99 games for the Phillies since he was acquired midway through last season and hit .250 with three homers and 33 RBIs. --- Outfielder Josh Hamilton wasn't feeling great physically in his first home game since returning to the Texas Rangers in a trade with the Los Angeles Angels last month, but his outlook couldn't be better. The former American League MVP believes he can recapture the magic he once enjoyed while helping Texas to back-to-back World Series appearances in 2010 and 2011. "I feel nervous," Hamilton said on Thursday. "If you don't feel nervous anymore, then you don't need to be doing this. But, yes, I think I can do what I've done in the past." Hamilton went into Thursday night's game against the Boston Red Sox dealing with a cold, but went 2-for-4 with an RBI and was given a standing ovation by the fans in his first at-bat. "It was a good feeling," he said. "I appreciated it a lot. You don't know what to expect. To hear the fans cheer, stand, it means a lot. It brought back some good memories." (Editing by Larry Fine) ))
