The Giants, entering Sunday's series finale against Colorado on a seven-game winning streak, are at least putting pressure on the NL West-leading D-backs, who have lost three in a row.

While the Brewers look to inch closer to nailing down the National League Central title, Reds starter Dontrelle Willis is simply looking for his first win of the season on Sunday.

The D-backs lead the Giants by five games with 10 to go after taking their third straight loss — a 3-1 setback to the last-place Padres on Saturday — but the National League West leaders are still sitting pretty.

A rookie will battle a veteran Sunday in Washington, but both the Marlins' Brad Hand and the Nationals' Chien-Ming Wang come in with something to prove.

Ervin Santana allowed five runs on two homers in the first vs. the O's, and the offense couldn't rally back, scoring only two runs, off a sac fly and a ninth-inning triple.

Roy Oswalt tossed seven shutout innings, and Shane Victorino drove in three runs as the Phillies beat the Cardinals, 9-2, on Saturday at Citizens Bank Park to clinch their fifth straight National League East title.

The Royals kept rolling with their seventh straight win on Saturday, knocking off the Chicago White Sox, 10-3, before a Fan Appreciation Night crowd of 31,264 at Kauffman Stadium.

Ryan Braun and Yuniesky Betancourt homered to back Yovani Gallardo, who struck out a career-high 13 in six innings, as the Brewers crept closer to the National League Central title with a 10-1 victory over the Reds at Great American Ball Park on Saturday.

The Marlins were able to break through on Donnie Murphy's first homer of the season, a two-run shot in the 13th inning Saturday that lifted the Marlins to a 4-1 win over the Nationals and validated a fine performance from Chris Volstad.

A fifth consecutive National League East championship had been a formality for the Phillies for months. Their opponent in the National League Division Series is far from final.

The Rangers were down three runs early but rallied to defeat the Mariners, 7-6, at Safeco Field on Saturday night, powering their way to a 4 1/2-game lead in the AL West.

Yovani Gallardo made history in the fifth inning of Saturday night's game when he became just the second Brewers pitcher to strike out four batters in an inning.

In order to avoid being swept for the third time this month, the White Sox are going to have to find a way to do something they haven't been able to do all season — solve Bruce Chen. John Danks starts for Chicago in Sunday's series finale.

The Angels will need a solid start from Jered Weaver on Sunday against the Orioles and right-hander Alfredo Simon. Weaver is pitching on three days' rest for just the second time this season.

While the Rangers look to hold off the Angels in the AL West race over their final 10 games, they must first take down Mariners ace Felix Hernandez on Sunday.

While Philadelphia clinched the National League East with its win Saturday, the visiting St. Louis Cardinals still have plenty to play for Sunday.

Engaged in a pitching duel, Tim Hudson dominated the Mets with eight shutout innings, and Chipper Jones' go-ahead single in the eighth helped Atlanta claim a 1-0 win.
