Looking to build on a thrilling walkoff win, the Giants try to continue their recent success against the Padres as these NL West rivals play the second of three Saturday night.After suffering a three-game sweep at Milwaukee, San Francisco (10-7) returned home to beat San Diego 3-2 in Friday's series opener. Angel Pagan came through with a game-ending double with one out in the ninth inning, sending the Giants to their fourth consecutive home win."It's one of those situations you want to be the guy," Pagan said. "I wanted to be in that situation. I wanted to get the hit. We needed that win after getting swept in Milwaukee."San Francisco improved to 24-9 over the last 33 matchups in the series, including a 13-4 mark at home while posting a 2.35 ERA.The Giants now turn to Tim Lincecum (1-0, 5.63 ERA), who after allowing six runs in as many innings against Colorado on April 9, gave up a pair of two-run homers in the first Sunday in a 10-7 road win over the Chicago Cubs. The right-hander went on to throw four scoreless frames before being removed."It just comes down to focus, executing your pitches when you need to. I could have ended that inning with two runs maybe. I guess I just didn't focus the way I should have," he said."I didn't have a good rhythm. Everything seemed a little off, especially with the offspeed pitch. After that I kind of settled down and everything started working again."While opponents are hitting just .217 against Lincecum, he's walked 12 in 16 innings.Lincecum had gone 10-4 with a 1.84 ERA over his first 19 starts against the Padres (5-11) before getting hit hard in each of the last three. He's 0-1 with a 7.02 ERA over that stretch despite striking out 20 in 16 2/3 innings.Yonder Alonso is 1 for 12 with five strikeouts against Lincecum. Chase Headley, though, is 7 for 20 with two home runs since the start of 2010.Headley, who made his season debut Wednesday after missing the first 14 games due to a broken left thumb, went 1 for 3 with a homer and two RBIs on Friday. Alonso, Jedd Gyorko, Kyle Blanks and Nick Hundley -- the team's 5-6-7-8 hitters -- however, were a combined 0 for 13.San Diego gives the ball to Clayton Richard (0-1, 5.28), who's compiled a 1.64 ERA over his last two starts. The left-hander gave up two hits and overcome four walks to throw six scoreless innings in Sunday's 2-1 loss to Colorado."You'd like to see a solid pitching effort supported by enough runs to get by, but our offense couldn't get going," manager Bud Black told MLB's official website.Richard is 6-4 with a 3.29 ERA in his last 11 outings versus San Francisco. He had dropped three consecutive starts in the series before surrendering one unearned run and five hits over eight innings of a 7-1 victory Aug. 19.Richard has struggled against Buster Posey, who's 6 for 17 with a homer in their matchups. While the reigning NL MVP went 1 for 2 with an RBI on Friday, he's batting .150 over his last seven games."It's a matter of keep on grinding and keep working," he said.
