The Dodgers have optioned newly acquired Darwin Barney to Triple-A Albuquerque and completed their trade for the infielder by sending Single-A Great Lakes right-hander Jonathan Martinez to the Cubs.

The 20-year-old Martinez has a 3.47 ERA in 19 starts this year, with 91 strikeouts in 106 1/3 innings against 129 baserunners.
