Four weeks prior to acquiring Mat Latos and Alex Wood in trades with the Miami Marlins and Atlanta Braves, the Los Angeles Dodgers added to their organizational pitching depth by signing Trevor Cahill to a Minor League contract.
Cahill began the season with the Braves, but was released June 20 after going 0-3 with a 7.52 ERA over 15 games (three starts). He made one appearance with the Arizona League Dodgers and one start with High-A Rancho Cucamonga before moving on to Triple-A Oklahoma City.
However, Cahill elected to opt out of his deal and become a free agent, according to Ken Gurnick of MLB.com:

The 27-year-old right-hander started six games for the OKC Dodgers, finishing 1-3 and throwing a combined 28.2 innings while posting a 6.28 ERA and 1.61 WHIP. Opponents hit .286/.359/.411 against Cahill at the Triple-A level and he allowed at least four earned runs in half of his starts.
Cahill’s best season in the Majors came in 2010 when he was a member of the Oakland Athletics pitching staff and won a career-best 18 games. He was named to the American League All-Star team that season, his lone trip to the Midsummer Classic.
Over his seven-year career, Cahill is 64-72 with a 4.16 ERA, 4.28 FIP and 1.37 WHIP in 201 games (173 starts). He joins David Aardsma as pitchers who were once on the OKC Dodgers’ staff and opted out of their deal. There was never any public indication from Dodgers manager Don Mattingly or the front office Cahill received consideration for a promotion to the Majors.
