Cobb (elbow) will make a final rehab start for Triple-A Durham on Saturday before joining the Rays next week, Marc Topkin of the Tampa Bay Times reports.
His long road back from May 2015 Tommy John surgery almost complete, Cobb will take the mound one more time for the Bulls in a final effort to work out kinks and stretch out his arm. The 28-year-old has had an up-and-down rehab process, with an extended break from game action at one point to remedy some mechanics and fatigue-related issues. Cobb will try to rebound from his last start on Aug. 22 against Norfolk, an outing where he gave up five earned runs on nine hits and two walks over four frames. He's not scheduled for a soft landing when he arrives in Tampa either, as the right-hander is slated to face the Blue Jays on Sept. 2 or 3.
