The rehabbing actor kept it low-key and zero alcohol during a screening party of his 1989 film over the weekend.

Charlie Sheen might have watched his Wild Thing character on film over the weekend, but he was anything but during an All-Star screening party of Major League at his house over the weekend.

Sheen, 45, mingled with invited baseball greats while serving ginger ale and chocolate milk, according to Major League director and screenwriter David S. Ward, who was a guest.

"One thing Charlie was clear about when he gave the invitations -- if you want a drink, you better bring your own," Ward tells The Hollywood Reporter. "He said there's going to be no drinks here.

"And no one drank (alcohol),” Ward added. “It was strictly ginger ale, maybe a little chocolate milk. We ate a lot of Red Vines."

The actor has been undergoing rehab and is on leave from his CBS show Two and a Half Men (he returns next week).

The party featured Giants pitching ace Brian WilsonKenny Lofton, Todd Zeile, Eddie Murray and Lenny Dykstra. Also present: actor Colin Farrell.

Ward says that Sheen looked like he was in "good shape. He told me he's working out everyday.”

In fact, the actor showed off his latest skill. He's learned how to hit left-handed.  "I saw some tape of him hitting," Ward says. "He hits very well."

Sheen has expressed strong interest in making a new version of Major League and Ward has already written a script for the new project.

The highlight of the evening was trying on Babe Ruth's 1927 Championship ring, which Sheen had purchased at auction. "To wear the ring Babe Ruth once wore. It was humbling for a baseball fan," says Ward.
