(My Sportsbook) - The Seattle Mariners shoot for their seventh straight win over the Oakland Athletics tonight when the AL West foes start a three-game set at Safeco Field.

These teams met earlier in the season at Oakland, where the Mariners completed a three-game sweep. Seattle also swept the A's at Safeco to end last season.

The Mariners enter tonight's contest surprisingly alone atop the AL West standings after an impressive April that saw them go 13-9 just one year removed from losing 101 games and finishing 39 games back in the division.

Seattle, though, has hit the skids of late and has dropped three of four after losing two of three to the Chicago White Sox, including a 6-3 setback in Wednesday's rubber match at U.S. Cellular Field.

Adrian Beltre went 4-for-4 with an RBI, while Ken Griffey Jr. added a two-run double and scored a run in the loss. Shawn Kelley (0-1) took the loss while Mariners starter Erik Bedard yielded three runs on six hits and three walks in five-plus innings of work.

Heading to the hill for the Mariners tonight will be right-hander Carlos Silva, who is coming off his first win of the season. Silva defeated the Los Angeles Angels of Anaheim on Saturday, surrendering three runs and six hits in five innings to up his mark to 1-2 on the year, while lowering his earned run average to 6.14.

Silva has faced the A's 12 times (11 starts) and is 4-3 against them with a 3.08 ERA.

Oakland, meanwhile, will counter with left-hander Dana Eveland, who has thrived in his young career against the Mariners, going a perfect 4-0 with a 2.55 ERA in his four starts against them.

Eveland comes into tonight's tilt sporting a ledger of 1-1 to go along with a 5.95 ERA. Eveland picked up the win on Sunday against Tampa Bay, as he held the Rays to a run and four hits in five innings.

On Thursday, Dallas Braden was solid on the hill while Ryan Sweeney went 2- for-5 and made a game-saving catch in the eighth, helping Oakland earn a split in its rain-shortened two-game set from the Texas Rangers, 4-2.

Matt Holliday hit his first home run of the season in the win, while Landon Powell, Kurt Suzuki and Jack Cust drove in a run each in the win for the A's, who have won three of four.

Braden (3-2) gave up five hits with six strikeouts and four walks over five scoreless innings to get the win. Michael Wuertz got his first save of the year despite giving up a homer in the ninth.

Eric Chavez was in the starting lineup, but was scratched prior to the first pitch due to a strained right forearm. Chavez has played in only three of the previous 12 games coming in because of the injury.

Oakland won 10 of its 19 matchups with the Mariners last season, but Seattle is 26-15 in the series since the start of the 2007 campaign.
