Rangers center fielder Josh Hamilton will miss four-to-six weeks following surgery to repair a partial tear in an abdominal muscle. "That's great because we thought it would be longer," manager Ron Washington said Monday. "It looks like we'll have a chance to get him back after the [July] All-Star break. At least it won't be September." Texas feared that the injury was a sports hernia, similar to what sidelined second baseman Ian Kinsler for 12 weeks.
