He faces a long rehab.
"Six months," Green said. "And a full six months."
The timing of his injury was terrible. Green might be the Brewers' everyday first baseman were he healthy, and would at least be playing extensively at first and third because of injuries to other players. Instead, Green began the season on the disabled list, then suffered a setback early last week in extended spring camp.
Raasch examined the hip on Thursday, and surgery was deemed necessary.
"I've played with it for years now, but it's gotten to the point where I literally can't," Green said. "It will be nice to have it finally healthy."
The news was much better for Jeff Bianchi, another infielder on the DL with a hip injury. After beginning a rehab assignment with five games at Double-A Huntsville, he was promoted to Triple-A Nashville.
"I think we'll want to see him there about a week," assistant general manager Gord Ash said.
