Dodgers pitcher Zack Greinke is expected to begin a rehab assignment Friday when he starts for Class A Advanced Rancho Cucamonga, the team announced on Thursday.

The right-hander fractured his left collarbone in a melee with the Padres' Carlos Quentin on April 11 and had surgery two days later that was supposed to keep him out of action for about eight weeks. Greinke is ahead of that, but running and fielding also pose potential risks to the healing bone.

Greinke described his pitching arm strength as "pretty good" after a third bullpen session Tuesday. He's taken a couple of "dry swings" with a bat, "but I didn't try to hit an imaginary home run." He said catching throws is "pretty easy."

"I feel more than you would with a normal arm, but not anything major," said Greinke, whose start on Friday would come at Lake Elsinore.

Greinke, one of nine Dodgers players on the disabled list, is 1-0 with a 1.59 ERA in 11 1/3 innings this season.

Left-handed reliever Scott Elbert, who had two offseason elbow operations, is expected to throw a rehab inning.
