Tyson Ross began the season with back-to-back Quality Starts, but he’s gone just 1-6 with a 7.34 ERA since then and yesterday’s ugly outing versus the last-place Twins was apparently the final straw, as the A’s demoted the 25-year-old right-hander to Triple-A.
No corresponding roster move has been announced yet, but Yoenis Cespedes and Brandon McCarthy are both on the verge of returning from the disabled list and McCarthy figures to fill the empty rotation spot.
Ross has good raw stuff with a 92-mph fastball and sharp slider, but the 2008 second-round pick has yet to figure out big-league hitters. Since debuting in 2010 he’s made 17 starts and 27 relief appearances, throwing 122 total innings with a 4.86 ERA and 79/54 K/BB ratio. He’ll be back in Oakland soon enough, but Ross might be destined for the bullpen long term.
