Cobb (elbow), who made a successful return to game action Friday by firing two scoreless innings for High-A Charlotte, says he needed the recent time off to work on his mechanics, Roger Mooney of the Tampa Bay Times reports.

The rehabbing right-hander took seven days off from live action recently to hone the finer points of his delivery, and the extra work appeared to pay off Friday. Cobb explains that his unorthodox delivery necessitated the extra side work to find his arm slot after what was a 14-month layoff following Tommy John surgery. "The reason I took a step back was because I needed to make some major adjustments," Cobb said. "I figured those out, thankfully, now there are some minor adjustments to be made to become more repeatable."
