Mariners 2, Athletics 1

SEATTLE (AP) — Bobby Crosby's latest collision on the field might be costly for the Oakland Athletics.

Crosby, Miguel Tejada's rookie replacement at shortstop, was scheduled to return to Oakland on Wednesday morning to have an MRI done on his left knee after being knocked out of Tuesday night's game.

”With knees, you like to get some interior pictures before you make a guess,” head trainer Larry Davis said after Seattle's 2-1 victory over the A's. ”Even if he were here, he wouldn't play.”

Crosby was hurt in the second inning when he collided with left fielder Bobby Kielty after making a catch of Scott Spiezio's popup. Crosby's knee struck Kielty in the side.

Crosby stayed in, but left in the fourth.

”I saw him right at the last second,” said Kielty, who had the wind knocked out of him. ”I was going to dive head first, but I wasn't able to get down fast enough.”

It was the second collision in less than a month for the aggressive Crosby, 24, who had 22 homers and 90 RBIs at Triple-A Sacramento last season.

Crosby collided with A's starting second baseman Mark Ellis in a spring training game March 25, causing Ellis to suffer a torn labrum in his right shoulder that will cause him to miss the entire season. Ellis is awaiting surgery.

After beating the A's 2-1 in 14 innings on a balk Monday night, the Mariners used Raul Ibanez's two-homer game to win by the same score Tuesday night.

Ibanez homered to tie the game in the seventh and then again in the ninth.

”It was a tight game and it feels good to pull it out against a good team,” said Ibanez, who signed as a free agent in November to return to the Mariners after spending three seasons in Kansas City.

Ibanez hit a 2-2 pitch off Jim Mecir (0-1) to right to end the game. It was his first career multihomer game and he homered in his third straight game, giving him four this season.

The Mariners have won four straight, including consecutive 2-1 wins over the A's, to improve to 6-8 on the season.

”Hopefully, we can keep it going,” Ibanez said. ”This is what everybody on this team expects from us and all the fans expect from us. We expect to win ballgames.”

Ibanez, who hit 18 homers last season after hitting 24 in 2002, said he hit a fastball for his second homer, which bounced off the second-deck facade.

Despite his homers, Ibanez said he didn't consider himself a power hitter.

”I'm not a power guy,” he said. ”I'm just trying to hit line drives and base hits.”

The Mariners can use all the power they can get.

After 14 games, the Mariners have 10 home runs, the least in the American League. In 2003, the Mariners ranked 13th among the 14 AL teams with 139 homers. Only Tampa Bay had less with 137.

Ron Villone (1-0) pitched the eighth and ninth for Seattle, allowing just one walk.

Ibanez tied the score at 1 leading off the seventh, a shot to right off Rich Harden.

Damian Miller gave the A's a 1-0 lead in the second when he hit a 2-2 pitch from Ryan Franklin into the A's bullpen in left field.

Harden and Franklin each went seven strong innings.

Harden allowed one run on three hits and four walks, with nine strikeouts. Franklin gave up one run on three hits and a career-high five walks, with four strikeouts. He retired the final 11 A's he faced.

Franklin said the Mariners were ”shocked” when they started off 2-8.

”I think the whole team was like, 'There's no way this could happen to us,”' Franklin said. ”We're not used to losing around here and nobody likes it.”

Notes: Mariners C Ben Davis singled in the third for his first hit of the season and his first since March 14 in spring training. Davis was 0-for-11 this season before his hit after being 2-for-35 this spring. … Oakland's Jermaine Dye had his 13-game hitting streak end with an 0-for-4 game.
