In his second rehabilitation stint at Triple-A Memphis, Greene has been raking. The infielder is trying to come back from an anxiety issue that has affected him throughout the 2009 season. It's conceivable that he could be activated before the Cardinals begin a road trip on Tuesday.
"He's getting his work in," general manager John Mozeliak said. "He's feeling good and we're going to revisit it this weekend. There's a chance that we'll contemplate activating him shortly."
In his last 10 games at Memphis, Greene has batted .343 and cranked four home runs. There's no everyday opening for him with the Cardinals, but he could provide infield depth and a right-handed bat off the bench.
"I know we're seriously talking about him," manager Tony La Russa said.
Meanwhile, Troy Glaus visited his teammates on Wednesday but is only geographically close to the big league roster. Glaus, who is attempting to come back from offseason shoulder surgery, recently had a setback in that rehab when he suffered back discomfort. He's been taken off of his rehab and consulted with team officials in St. Louis this week.
Glaus' injury has complicated the club's interest in trading him to a team that could better use him. Glaus' shoulder issue prevents him from playing third base, and the Cardinals are set at first base and in left field.
"I don't expect him here shortly," La Russa said.
