Paulino experiences right shoulder soreness

CHICAGO -- The White Sox returned Felipe Paulino from his rehab assignment with Triple-A Charlotte because he experienced right shoulder soreness. He was placed on the disabled list April 19 with right rotator cuff inflammation

Paulino, 30, posted an 0-2 record with an 11.29 ERA in four starts for the White Sox. He allowed 10 runs on 13 hits over 3 2/3 innings in his last start against the Rangers during a 12-0 loss on April 18.

His rehab starts produced equally poor results. Paulino yielded 29 hits and 16 walks over 19 2/3 innings and continued to work with high pitch counts.

"I don't know if he's seriously injured, but I think you look at the numbers and everything that's right there [and] you still think there's something there," said White Sox manager Robin Ventura. "We'll continue to evaluate that."

Paulino's rehab assignment was scheduled to end around June 1. But this latest move could lead to a new injury rehab assignment for Paulino, whom the white Sox signed to a $1.5 million deal for 2014 with a $4 million club option ($250,000 buyout) for '15. Prior to his White Sox debut, Paulino had not pitched in the big leagues since June 2012 following ulnar collateral ligament replacement surgery and a cyst on his shoulder.
