McGee threw a scoreless inning in his final Triple-A rehab stint and could return to the Rays Friday, Marc Topkin of the Tampa Bay Times reports. With Brad Boxberger looking very strong (10 saves, 1.29 ERA, 12.9 K/9), there's a good chance McGee will find himself in a set-up role upon his return. The Rays could still use McGee in save situations with a lefty-heavy slate of hitters though, so take a wait-and-see approach since his value is fairly limited without appearances in the ninth inning.
