Oakland Athletics
Coming into the 2010 season, Ross was ranked as Oakland's 6th-best prospect. Despite not having pitched above Double-A, Ross made MLB roster while making only 5 spring training appearances. Ross made his MLB debut on April 7, 2010, against the Seattle Mariners. He went 2.1 innings, allowing no runs on one hit. He struck out the first batter he faced, his childhood idol Ken Griffey Jr., and walked one. In his next appearance, on April 11, he pitched 3 innings against the Angels and recorded his first career MLB save. On May 11 against the Texas Rangers, he picked up both his first MLB career win and first MLB blown save. Ross worked out of the bullpen until July 6, when he was sent down to Triple-A to be groomed back to a starter role. Ross had a 5.49 ERA in 39 innings with the A's, and posted a 3.55 ERA in six starts for the Triple-A Sacramento River Cats of the Pacific Coast League with 30 strikeouts in 25.1 innings.
Ross was one of the A's final cuts in spring training 2011, but was recalled to join the bullpen in early April. He took the place of the injured Dallas Braden in the rotation, making six starts until he himself was injured and placed on the DL with a strained oblique. Ross had a 2.75 ERA in 36 innings at the time of the injury. He did not return to the Oakland A's that season, finishing out 2011 in Triple-A, where he had a 7.61 ERA in 9 starts.
Ross was pegged as the A's fifth starter out of spring training in 2012, but was sent down to the Sacramento River Cats at the start of the season because Oakland would not need a fifth starter until mid-April. He made his first start for the A's on April 17, and continued to start until he was optioned back to Sacramento on May 31 with a 6.51 ERA. He then shuttled between Triple-A and the A's, starting until the September roster expansion, when he rejoined the parent club as a reliever. In his five stints with Oakland, Ross was 2-9 in his 13 starts and had a 6.50 ERA overall. He had a 2.99 ERA in his 15 games (13 starts) with the River Cats.
During his tenure with the Oakland Athletics, Ross wore number 66 for the name of the street where he first played baseball, 66th Avenue, located on the northwestern boundary of the Oakland–Alameda County Coliseum.
San Diego Padres
On November 16, 2012, Ross was traded to the San Diego Padres with minor league infielder A. J. Kirby-Jones for Andy Parrino and Andrew Werner.
