San Diego @ San Francisco preview

Last Meeting ( Apr 20, 2013 ) San Diego 0, San Francisco 2

The San Diego Padres look to avoid another series sweep Sunday at AT&T Park when they face the San Francisco Giants, who have won two in a row since being swept in three games by Milwaukee. The Padres have already been swept in two series by Colorado, and are in danger of losing three straight to the Giants, who won the first two games by a combined total of three runs. The Giants have won 14 of their last 20 games against San Diego.

San Francisco used a strong outing from Tim Lincecum and a two-run homer by Pablo Sandoval to win 2-0 on Saturday, but Sandoval left the game in the seventh after hitting a foul ball off his right foot. It is unclear whether he'll miss any time. The Padres’ starting rotation is a question mark after Tyson Ross landed on the disabled list Saturday with a minor dislocation of his left shoulder. Another starter, Clayton Richard, was scratched before Saturday’s game because of flu-like symptoms, but is hoping to return Tuesday.

PITCHING MATCHUP: Padres LH Eric Stults (2-1, 3.94 ERA) vs. Giants LH Barry Zito (2-1, 4.86)

Stults did it all in his last start, giving up three runs over six innings and hitting a three-run homer in a 6-3 victory Monday against the Dodgers. Stults is 4-2 with a 5.10 ERA in nine career starts against the Giants, and has earned the win in four of his last six starts against San Francisco dating to 2009. Sandoval has six hits in 10 at-bats against Stults, who went 2-0 with a 4.95 ERA in four games (three starts) against the Giants last season.

The Giants had won 16 straight Zito starts before Tuesday, when the veteran gave up nine runs over 2 2/3 innings. He opened the season by tossing seven scoreless innings in each of his first two starts. Zito, 34, has gone 4-9 with a 4.80 ERA in 21 games (20 starts) against San Diego. Chase Headley is 8-for-31 (.258) with one home run against Zito, who is 126-7 over 164 career starts when receiving at least four runs of support.
