Walls will start at shortstop and bat seventh in Thursday's game against the Athletics.
Though he appeared to be at risk of moving into more of a part-time role when the Rays recalled infielder Junior Caminero from Triple-A Durham on Aug. 13, Walls still looks to be the team's top option at shortstop. Walls will pick up his fifth start in six games Thursday, while Jose Caballero has instead taken the bigger hit from a playing-time perspective following the arrival of Caminero. Caballero boasts the better fantasy profile of the two players thanks to his willingness to run (35 steals in 48 attempts this season), but the Rays seem to place greater value on Walls' defense at shortstop.
