 Biographical Information
 High School
Ross hit .450 as a high school freshman in 2002. The next year, he hit .313 and was 2-1 with a 1.38 ERA. In 2004, Tyson batted .366 and went 9-2 with a 1.53 ERA and 100 strikeouts. He was with the US in the 2004 World Junior Championship, going 1-0 with a 4.50 ERA and four strikeouts in two innings of work. In his senior year of high school, he posted as 12-1, 0.71 record and fanned 130 batters. He was 0-1 with a 2.45 ERA in the 2005 Junior Pan Am Championship, striking out 7 in 7 innings. He shut out Cuba for 5 innings in the pool play phase.
Ross went 6-4 with a 3.19 ERA as a freshman at the University of California and struck out 85 in 84 2/3 innings. He was named the school's freshman of the year. He was 6th in the Pacific-10 Conference in ERA.
In 2007, Ross fell to 6-6 but his ERA was 2.49 and he struck out 120 in 115 2/3 IP. He was third in the PAC-10 in strikeouts and second to Preston Guilmet in ERA. The strikeout total was the second-highest in school history. He won the Rawlings Gold Glove for college pitchers (17 putouts, 23 assists, 2 pick-offs, no errors) and made first-team All-Pac-10.
Ross spent the summer of 2007 with Team USA, going 4-1 with a 0.82 ERA, 39 K and 7 walks in 43 2/3 innings. He led the team in strikeouts and innings, was second to Mike Minor in wins and second to Brett Hunter in ERA. Ross allowed one run and fanned 10 in 8 2/3 innings in the 2007 Pan American Games; he finished second to Adiel Palma in Ks. Facing a Dominican national team with six former major leaguers, he struck out 7 and allowed one run in 6 2/3 innings for the win. He tossed two scoreless relief innings and fanned 3 in the Gold Medal game in a loss to the Cuban national team. He went 1-1 with a 0.64 ERA in the 2007 World Port Tournament.
 Minor leagues
Ross made his pro debut with the Kane County Cougars. On June 24, he faced the Quad Cities River Bandits and allowed no hits, walks or runs in two innings, striking out two. He had a 0-1, 4.66 record for the year with Kane County.
Despite a 10-11, 4.16 record in two minor league seasons and no AAA experience, Ross made the Athletics' roster out of spring training in 2010. He made his major league debut relieving Justin Duchscherer with a 5-4 deficit in the 6th inning against the Seattle Mariners. He began by whiffing Rob Johnson to end that frame. He tossed shutout ball in the 7th and 8th as the A's tied the game at 5. Brad Ziegler relieved Ross and Oakland would go on to win, 6-5. His first major league win was an eventful one. He came on in the 11th inning as the 7th A's pitcher of the night on May 11th against the Texas Rangers; staked with a 6-5 lead on a home run by Daric Barton, he blew the save opportunity, becoming the third A's reliever of the evening to record a blown save. Manager Bob Geren had earlier moved designated hitter Gabe Gross to the field, meaning Ross had to come to bat in the 12th, when he promptly struck out; he was the first A's pitcher to bat in a non-interleague game since 1995. The A's took a 7-6 lead in the 13th, and this time he held the Rangers scoreless in the bottom of the frame to get the credit for the win.
