Locke gave up consecutive doubles to Jerry Sands and Rod Barajas in giving up a run in the second, then allowed two singles and two walks in a two-run third.
After that, the Pirates could muster little offense to help him. Alex Presley helped keep the score close with a solo homer in the sixth that made it 3-2 Dodgers, but a four-run Dodgers seventh that featured a three-run blast by James Loney sealed the Pirates' fate.
The Pirates mustered only six hits and struck out 12 times in what has been an all-too-familiar pattern for them.
