The Los Angeles Dodgers take aim at a fourth straight win on Tuesday and try to spoil the San Diego Padres' home opener in the first of three games at Petco Park.

Los Angeles received some tremendous starting pitching over the weekend, as it blanked the Pittsburgh Pirates twice and held them to just two runs in sweeping the three-game set at Dodger Stadium.

On Sunday, Adrian Gonzalez went 3-for-4 with four RBI and the Dodgers finished off a three-game sweep of the Pittsburgh Pirates with a 6-2 victory on Sunday. Justin Sellers added a solo home run and Matt Kemp contributed a sacrifice fly for Los Angeles, which saw starter Hyun-Jin Ryu (1-1) pick up the first win of his career.

The South Korean native struck out six and surrendered just two runs on three hits and two walks over 6 1/3 innings of work.

Los Angeles hopes Josh Beckett can continue the string of strong starting pitching, as he tries to bounce back from a loss to San Francisco in his first start. Beckett allowed five runs (3 earned) and six hits in six innings in that one.

"I made some pitches when I needed to, and didn't make some when I needed to," Beckett said.

Beckett has faced the Padres seven times and is 5-2 with a 2.09 ERA against them.

San Diego, meanwhile, will counter with lefty Clayton Richard, who was roughed up by the New York Mets in his first outing. Richard led the NL with 31 home runs allowed last season and picked up right where he left off, as he surrendered three in the loss to the Mets. In all, he allowed eight runs (7 earned) and seven hits in just 4 1/3 frames.

Richard is 6-3 lifetime versus the Dodgers with a 3.16 ERA in 13 starts.

"When you're not able to command down in the zone without your best stuff, it's a bad night," Richard said after that outing. "My last couple of side (sessions), I felt good. My last outing (March 29), I felt good. Then, I got out there tonight and it wasn't there."

San Diego limps home after starting the season with a 1-5 road trip. After losing two of three to the Mets to open the year, the Padres were swept over the weekend by the red-hot Colorado Rockies.

Now the Padres return home to a newly-designed Petco Park, where the fences were moved in from 402 feet to 391 feet from the right-field porch to the right-center gap and lowered to just under 8 feet, matching the rest of the outfield wall.

In left-center, the fence came in from 402 feet to 390 feet.

San Diego is 22-22 all-time in the first home game of the season.
