Burriss is tied for the major league lead with 22 hits this spring and is making a strong push to win the Giants' starting second base job in a competition with Kevin Frandsen.

"It's been a long process. I was working the whole offseason," said Burriss, hitting .415 with six RBIs. "I'm trying to make sure I have a good approach when I step up to the plate.

"It's kind of hard to call it a competition. We're both competitive guys, but not between us. We're trying to get a ring for this organization," Burris added. "That's why we keep pushing ourselves."

Pablo Sandoval and Fred Lewis also had two hits apiece in the sixth inning, when the Giants got 11 hits and sent 14 batters to the plate.

Sandoval was playing in his first game since being struck in the mouth by a grounder that took a bad-hop in the fifth inning of a game against the Chicago Cubs on Wednesday. Sandoval had a chipped tooth repaired Thursday.

Bengie Molina and Jesus Guzman also had two-run singles in the Giants' sixth.

Frandsen had two hits, including a double, and raised his spring average to .315.

"He (Burriss) is hitting it well and playing good defense. He and Franny both," Giants manager Bruce Bochy said. He's a smart player. I like the way he has responded to the competition."

San Diego second baseman David Eckstein had three singles, and Kevin Kouzmanoff had two hits, including his fourth double of the spring.

Giants starter Joe Martinez gave up two runs in four innings. The Padres scored two runs in the first on a bunt single, two infield singles, a walk and two sacrifice flies.

San Diego starter Walter Silva, in competition for the final spot in the Padres' rotation, gave up one run in four innings. He allowed two singles and a walk.

"So far, he's been very good," San Diego manager Bud Black said.

Notes: Giants catcher Buster Posey made his first start of the spring in a split-squad game against Oakland, going 0-for-2 against top A's prospect Trevor Cahill before hitting a solo homer off Russ Springer. Posey is hitting .421 with seven RBIs in his first spring training since signing for a $6.2 million bonus as the Giants' first choice in the 2008 draft. ... Randy Johnson had a bullpen session Saturday and is scheduled to start against Seattle on Monday, his preference. The Giants had given Johnson the option of pitching in a minor league game. "I need to get the most out of it, and I think I would do that by pitching facing major league hitters," Johnson said. "My starts are kind of numbered now. Missing that one start sent me back pitches wise and innings wise. I need to take advantage of the remainder of my starts." Johnson pitched a minor league game March 13 but missed a scheduled start March 18 because of biceps soreness. He has given up one earned run with 12 strikeouts in 8 1-3 innings this spring. ... The Giants acquired minor league shortstop Sergio Santos in a trade with the Chicago White Sox. Santos, a former No. 1 draft pick by Arizona, could provide an alternative at Triple-A Fresno if Burriss wins the second base job.
