ST. PETERSBURG -- Wilmer Font left Friday night's Rays-Astros contest at Tropicana Field in the sixth inning with an unknown injury.
The Rays have not yet announced the nature of the injury to the right-hander.
Font pitched five scoreless innings before walking Jake Marisnick to start the sixth. He then fell behind 3-1 to Alex Bregman. That's when Rays manager Kevin Cash and a trainer made a mound visit. A moment later, Cash signaled for right-hander Diego Castillo to enter the game.
