The North Siders got their long-awaited revenge for last October’s three-game Division Series sweep. OK, not really, but they did get a grand slam from Micah Hoffpauir off an ineffective Ramon Troncoso, who couldn’t get his sinkerball working or keep his fastball down in a rough fifth inning that also included a costly error by Hector Luna. The Dodgers got two hits from James Loney, but no more than one by anybody else. Tony Abreu drove in a pair with a second-inning single, and Blake DeWitt drove in the Dodgers’ other run with a fourth-inning single after Matt Kemp singled and stole second. … The fifth-starter race is officially under way, but Rick Honeycutt said they’re not doing a lot of evaluating this early in the spring. Claudio Vargas started, had a rough first inning, then breezed through the second. Eric Milton followed, had a rough third inning and then a rough fourth but somehow didn’t give up a run. Dodgers fall to 0-1 for the spring. At the Giants tomorrow.
