(My Sportsbook) - The Los Angeles Dodgers and San Diego Padres resume what's been an evenly-played four-game season-opening series so far when the two National League West members square off again tonight at Petco Park.

The reigning division champion Dodgers took Monday's lid-lifter by a 4-1 count, but the Padres evened things up with a 4-2 decision last night. San Diego scored three times in the bottom of the sixth inning to erase a 2-1 deficit, with Chase Headley's two-RBI double plating the go-ahead runs.

Kevin Kouzmanoff finished 2-for-4 with two runs scored for the Padres, who got six strong innings out of starting pitcher Chris Young as well as quality work from the bullpen.

Young held Los Angeles to two runs on five hits and struck out five before exiting after six innings. Relievers Edwin Moreno and Duaner Sanchez made the lead stand before turning the game over to Heath Bell, who struck out the side in the ninth to earn his first save of the season.

Randy Wolf, who spent part of last season with the Padres, took the loss for the Dodgers after surrendering four runs over 5 1/3 innings of work.

Matt Kemp accounted for two of Los Angeles' five hits on the night, with Russell Martin and Casey Blake driving in the Dodgers' only runs.

Los Angeles will try to rebound tonight behind Chad Billingsley, who emerged into a top-flight starter in his third major-league season last year. The former first-round pick established career bests in virtually every category, amassing a sturdy 16-10 record and a 3.14 earned run average in 35 games (32 starts) and ranking fifth in the National League with 201 strikeouts.

Only one of Billingsley's 16 wins came against the Padres, last year's cellar- dwellers of the NL West, although he did held San Diego to just six runs over 20 innings in four outings against the club in 2008. The 24-year-old had a 1-2 record in those games.

Billingsley is 5-3 with an outstanding 2.37 ERA over 13 lifetime appearances (9 starts) against San Diego, and 2-1 with a 2.53 ERA in eight previous trips to the Petco Park mound, four of which have been starts.

The Padres will go with newcomer Walter Silva, a 32-year-old veteran of the Mexican League who won the spot in the team's revamped rotation during the spring. The right-hander will be making his major league debut tonight.

Silva spent 2008 with the Monterrey Sultans and put together a 7-8 record with a 4.21 ERA over 115 1/3 innings.

The Dodgers won 11 of 18 meetings with the Padres last season and five of the nine tests held at Petco Park.
