The visiting Giants will try to end Cashner's recent run of success Saturday.San Francisco (84-68) managed two of its three hits off rookie Odrisamer Despaigne during a 5-0 loss Friday that left the club 3 1/2 games behind the first-place Los Angeles Dodgers in the NL West and one ahead of Pittsburgh for the wild-card lead."We had a tough time getting anything going," said manager Bruce Bochy, whose team has totaled 10 runs and been shut out twice while going 2-4 since averaging 6.3 during a four-game winning streak.San Francisco now gets its first 2014 look at Cashner (4-7, 2.20 ERA), who is 2-1 with a 1.85 ERA in five starts since missing two months with shoulder soreness.The right-hander needed 92 pitches to shut out Philadelphia on Monday, striking out seven and allowing two hits in a 1-0 victory. Cashner didn't yield his first hit until the fifth when Domonic Brown reached on a bunt single."I felt I had enough to carry (a no-hitter) all the way through," Cashner told MLB's official website.Though Cashner is 3-3 in 10 home starts, he's posted a 1.34 ERA in those games. Of the 17 runs the Padres have scored with Cashner on the mound at Petco Park, seven have come over his last seven outings.All three of Cashner's career starts versus San Francisco came last season when he went 1-1 with a 3.24 ERA against the division foe. He gave up a run in six innings of a 2-1 victory in his only home start against the Giants.Buster Posey is 5 for 12 with two home runs against Cashner, but is 0 for 6 in the two games since batting .423 in his previous seven.Angel Pagan is 2 for 5 versus Cashner, but could miss this contest after he left Friday with a back issue. He missed the entire three-game set with Arizona this week because of the same ailment.It's also uncertain if Michael Morse will play after he re-aggravated an oblique injury Friday in his return from missing the previous 15 games with the same issue.After allowing a home run and striking out nine during a complete-game 5-1 victory over Arizona on Sept. 9, Yusmeiro Petit (5-4, 3.64) gave up four runs and struck out eight over seven innings of a 4-2 loss to the Dodgers on Sunday.Though the right-hander is 2-1 with a 2.05 ERA at home since replacing Tim Lincecum in the rotation, he's 0-1 with a 9.31 ERA in four overall road starts this season. He's allowed 11 runs and 14 hits in nine innings while not factoring in the decision over his last two starts away from home.Petit is 3-3 with a 5.18 ERA in 10 starts this season, and his first came at home against the Padres when he allowed three hits in six innings of a 6-0 victory April 29. He's since pitched two innings of scoreless relief versus San Diego.Seth Smith is 2 for 3 with a home run versus Petit and had an RBI double Friday as San Diego (72-81) improved to 4-1 on its final 10-game homestand.Teammate Alexi Amarista is batting .400 with 10 RBIs in eight games but is 1 for 6 against Petit.
Buster Posey has hit .338 and slugged .537 this season in at-bats to end on a fastball of at least 90 mph, both in the top 15 among qualified hitters. Andrew Cashner's average fastball velocity this season has been 94.3 mph.
