The Mariners have confirmed that right-hander Taijuan Walker and left-hander Roenis Elias will switch places in the rotation. Walker will now pitch on Wednesday against the Padres, while Elias will go on Thursday against the Red Sox, according to the Tacoma News Tribune.
The move was made in-part due to the large amount of right-handed bats in the Padres' lineup. Right-handed hitters are hitting .256 off of Elias during his career, so manager Lloyd McClendon decided to make the change in the rotation.
