PITTSBURGH -- Pirates shortstop Erik González had surgery on Thursday morning to repair the collarbone fracture he sustained when he collided with center fielder Starling Marte on Friday night.

The club announced that Gonzalez, who was placed on the 60-day injured list on Saturday, will return to “full Major League baseball activities” in approximately 10 to 12 weeks. The surgery, performed by Dr. Greg Altman at Allegheny General Hospital, was an open reduction internal fixation to repair and stabilize Gonzalez’s fractured left clavicle.

There is a more optimistic short-term outlook for Marte, who sustained an abdominal wall contusion and a bruised quadriceps in the collision with Gonzalez. Marte began light baseball activities on Wednesday, Pirates director of sports medicine Todd Tomczyk said, and he has progressed well since being placed on the 10-day injured list on Saturday.

“Very encouraging news at this time,” Tomczyk said.

It’s possible that Marte could be ready to play when he’s eligible to return on Monday. Pittsburgh could certainly use the speedy center fielder’s help, as the club’s outfield depth continues to be tested by injuries.

Left fielder Corey Dickerson, out since April 4 with a right posterior shoulder strain, is working his way through a throwing program, and he is still hitting without restrictions. He has not yet been sent out to start a Minor League rehab assignment, although Tomczyk noted that Dickerson is getting “closer” to doing so. The Bucs should soon make a decision regarding Dickerson’s next step.

Outfielder Lonnie Chisenhall (fractured right index finger) went 2-for-15 while playing right field, left field and first base in his first four rehab games for Triple-A Indianapolis. Tomczyk said Chisenhall is responding well to his first game activity since late March.

Rookie outfielder Bryan Reynolds, who went 6-for-12 with two doubles in his first four big league games after being called up on Saturday, did not start on Wednesday or Thursday due to the sore left quad that forced him to leave Tuesday’s game early. Reynolds took batting practice before Wednesday’s game and should be ready to play this weekend at Dodger Stadium.

Right fielder Gregory Polanco was also out of Pittsburgh’s lineup on Wednesday, but he was available off the bench and he returned to the lineup on Thursday afternoon. The Pirates did not want to use Polanco every day for an extended stretch after he came off the injured list on Monday, so they opted to have him sit on Wednesday and start Thursday.

Around the horn

• Catcher Jacob Stallings (cervical neck strain) has resumed light baseball activities, Tomczyk said Wednesday.

• Kevin Newman (right middle finger laceration) played his first professional game in the outfield on Tuesday, starting in center field for Triple-A Indianapolis as he began his rehab assignment. He played left field on Wednesday and went 2-for-3 at the plate. Newman had the day off Thursday and he is scheduled to start at shortstop on Friday and Saturday.

• Corner infielder/outfielder José Osuna, sidelined all season with lower neck discomfort, went 1-for-8 while playing one game in right field and another in left field to begin his rehab assignment with Class A Advanced Bradenton.
