OAKLAND, Calif. (AP) - Infielder Adam Rosales has been traded by the Oakland Athletics to the Arizona Diamondbacks for minor league right-hander Jeferson Mejia.
Rosales, who filled in at shortstop for 36 of the 38 games when starter Marcus Semien was hurt this season, is no stranger to switching teams. And the last-place A's are dealing again for prospects as they have historically done.
During an 11-day span late in the 2013 season, Rosales was claimed off waivers by Texas from Oakland, went back to the A's off waivers from the Rangers and then returned to Texas once again on waivers only to watch his former team win the AL West without him.
Rosales returned for a second stint with the A's this year. He was batting .234 with four homers and 27 RBIs in 71 games.
The 22-year-old Mejia was 1-1 with a 6.08 ERA in 18 relief appearances Class A Kane County before going to Class-A short season Hillsboro, where he made three relief outings. He combined to go 1-1 with a 6.21 ERA.
Last week, Arizona acquired catcher John Ryan Murphy from Minnesota for minor league left-hander Gabriel Moya.
