Barton may be looking at season-ending surgery

First baseman Daric Barton confirmed that he has a torn labrum in his right (throwing) shoulder and faces the possibility of season-ending surgery.

Barton, whom the A’s optioned to Triple-A Sacramento on June 22, is scheduled to visit Dr. Lewis Yocum in Southern California on Wednesday to decide the best course of treatment.

Barton said he originally hurt his shoulder in early April, while diving back to second base during a series in Minnesota.

A’s shortstop Cliff Pennington underwent surgery for a labrum tear in his left (non-throwing) shoulder in October. He was playing in exhibitions by March — roughly a five-month recovery period — to give an indication of Barton’s potential recovery time were he to have surgery.

The injury might partially explain why Barton struggled so badly with Oakland before his demotion. He hit .212 with no homers and 21 RBIs in 67 games and committed eight errors, some coming on bad throws.

Barton is hitting just .197 with no homers and four RBIs in 17 games with Sacramento.

Left-hander Brett Anderson is back with the A’s after having elbow ligament replacement surgery two weeks ago. He’s wearing a large black brace — and will do so for the next four to five weeks — to keep his arm immobilized. Anderson also had a bandage around his right leg, as doctors took part of a tendon from his hamstring and used it to build the new ligament for his left elbow. “Tommy John” surgery typically sidelines pitchers 12-18 months, and Anderson has come to grips with the long comeback trail he faces. “It sucks, but it’s a part of baseball,” he said before Tuesday’s game against Tampa Bay. “Sometimes you get hurt, but the good thing is the track record of success with this surgery has been pretty good. That’s kind of comforting in the back of your head.”

A’s manager Bob Melvin said he envisions infielder Adam Rosales returning to the major league club “at some point pretty soon.” Rosales entered Tuesday hitting .265 with two homers and nine RBIs for Sacramento in 13 games.
