Cahill had a 2.25 ERA in the 2008 Olympics to help the USA win Bronze. He got two tough calls, facing the Cuban national team and Japanese national team. He held Cuba to 2 runs in 5 and led to the runs with his wild pitching (2 walks, hit batsmen, wild pitch) in the first; against Japan, he threw 3 shutout innings. He got no decisions in the competition.
He made his major league debut on April 7, 2009 as the Oakland Athletics' starter against the Los Angeles Angels of Anaheim, giving up 3 runs in 5 innings of work. In spite of his youth, he ended up leading the Athletics in starts and innings pitched, going 10-13, 4.63 in 32 starts and 178 2/3 innings. Still, he failed to make the A's starting rotation out of spring training in 2010, but was called up quickly after injuries beset the team and he ended up being the A's sole representative at the 2010 All-Star Game. He had an even better season than his rookie year, going 18-8 in 30 starts, with a 2.97 ERA and only 155 hits allowed in 196 2/3 innings.
In 2011, Cahill made 34 starts, tied for most in the American League and pitched over 200 innings for the first time. His ERA went up by more than a run, to 4.16, and his record fell to 12-14. He did strike out 147 batters, a career-best. On December 9, he was sent to the Arizona Diamondbacks, along with reliever Craig Breslow, in return for Jarrod Parker, Collin Cowgill and Ryan Cook. He had a good first season for Arizona in 2012, pitching 200 innings with a 3.78 ERA and a record of 13-12; he struck out 156 against 74 walks. In 2013, however, he fell to 8-10, 3.99 and was limited to 26 games and 146 2/3 innings. He then struggled very badly at the start of the 2014 season, quickly losing his spot in the starting rotation. He was 1-6, 5.66 after 19 games when he was designated for assignment by the D-Backs on June 9th. They then decided to send him to the Class A Visalia Oaks to try to work out his problems, as they would have had to swallow some $17 million remaining on his contract had he been released outright, but he was hit hard in his first game there on June 12th, surrendering four runs on two hits - a double and three-run homer - two walks and two hit batsmen in only two innings. he came back to the majors on July 18th and stayed with the D-Backs for the rest of the year, but things did not improve much as he ended the season at 3-12, 5.61 in 32 games, including 17 starts.
On April 2, 2015, the Diamondbacks traded Trevor to the Atlanta Braves in return for minor league outfielder Josh Elander, in a move designed to open up a spot in the starting rotation for top prospect Archie Bradley. His first start for the Braves came on April 14th, but it was a bust as he did not make it out of the 3rd inning in an 8-2 loss to the Miami Marlins.
