Giants 2, Rockies 0
SAN FRANCISCO (AP) - Tim Lincecum struck out eight in eight innings to end a four-start winless stretch, and Pablo Sandoval homered for San Francisco.
Sandoval hit a solo home run in the fifth to break up a scoreless game. He was back in the lineup after missing three straight starts, two with tightness in his right calf and then Thursday's 11-0 loss to Arizona with the flu.
Lincecum (13-4) earned his first victory in five starts since beating Philadelphia on Aug. 1. He allowed four hits and walked three. Brian Wilson finished the Giants' majors-leading 17th shutout for his 31st save.

Nick Masset gave up a solo homer to James Loney, starting a wild ninth. Closer Francisco Cordero came on and loaded the bases with two outs, let in a run on a wild pitch and got Ramirez on a called third strike to end it.

Howard has 11 home runs and 29 RBIs in his last 15 games, with a .339 batting average.
Martinez allowed one hit and one walk in two innings. He didn't return after the second stoppage.
Moyer (12-9) worked 4 1-3 innings, allowing one run and four hits with five strikeouts. Brad Lidge, who leads the majors with nine blown saves, worked the ninth for his 26th save.

PHOENIX (AP) - John Hester hit a towering homer in his first major league at-bat, and Arizona scored seven runs in the third inning.
Alex Romero and Miguel Montero homered for Arizona, which won for the third time in 12 games.
Pinch-hitting in the sixth, the 25-year-old Hester hit a 2-2 delivery from Wilton Lopez, also making his first appearance in the majors, an estimated 420 feet off the batter's eye in center field.

Cubs 5, Mets 2
CHICAGO (AP) - Alfonso Soriano made up for several miscues in the outfield with a tie-breaking three-run homer in the eighth inning for Chicago.
Milton Bradley, who like Soriano has been booed by frustrated Cubs fans, led off the inning with a double, his third hit. He scored on Aramis Ramirez's single, tying the game 2-all.
After reliever Brian Stokes (1-3) walked Jeff Baker, Soriano hit an 0-2 pitch for his 20th homer of the season and first since July 29.
Kevin Gregg (5-5) got the win for the Cubs, who have won seven of 21 since Aug. 7.
Making his first start of the season, Pat Misch allowed six hits in a career-high seven innings for the Mets, who have lost six of seven.

Padres 9, Marlins 5
MIAMI (AP) - Will Venable had two RBI singles and Kyle Blanks added a two-run homer in San Diego's six-run second inning.
David Eckstein was 3 for 6 with two RBIs for the Padres. Everth Cabrera drove in two runs and Chase Headley - who replaced Blanks in that second inning - added three hits for San Diego, which is 3-1 on its six-game trip to Atlanta and Florida.
Chris Coghlan was 3 for 5 and Wes Helms went 2 for 5 with two RBIs for Florida, which has dropped six of nine.
Blanks' two-run homer was a costly shot for both the Padres and Marlins. Blanks aggravated a sore right foot as he rounded the bases, and neither he nor Florida starter Chris Volstad finished the inning.
San Diego sent 12 batters to the plate in the second. Volstad (9-11) was charged with six runs in 1 2-3 innings, his shortest outing in 41 career starts.
Kevin Correia (9-10) gave up 11 hits and four runs in 6 2-3 innings for San Diego.
