SEATTLE (AP) — Bret Boone gave the Seattle Mariners a lift again.

Mariners 4, Athletics 2,

He hit a tiebreaking two-run homer off Mark Redman in the eighth inning to give Seattle a 4-2 win over the Oakland Athletics Thursday night, the Mariners' fourth win in five games.

”When Boone is swinging the bat well, we seem to be a little bit of a different club,” manager Bob Melvin said. ”He's in a comfortable place right now. He can do some damage, and he certainly had a big hit today.”

Boone hit a home run for the second night in a row, and has hit three in the past four games. He had a game-winning 11th inning grand slam Monday against Boston.

With one out in the eighth, Randy Winn's routine grounder went off the glove of shortstop Bobby Crosby for an error. Boone then stepped to the plate and blasted Redman's changeup into the seats.

”I made the pitch I wanted to make,” Redman said. ”I had to throw it up enough for a strike and he just sat on the pitch he wanted to hit. Unfortunately, he beat me on it. Give me the same situation 10 more times and I'll throw the same pitch.”

Redman (6-8) lost his fifth straight start, and it was his second complete-game loss of the season. He settled down after allowing two runs in the first inning, holding the Mariners scoreless until Boone's homer. He allowed two earned runs on seven hits and three walks. In his previous four starts, Redman was 0-4 with a 9.75 ERA.

After being swept in the brief two-game series at Seattle, Oakland will return home to face the Anaheim Angels this weekend. The A's have lost seven of their last eight and 20 of 27 away from home.

”It does get old, but what the formula is I don't know,” A's manager Ken Macha said. ”Not many teams get a winning record on the road. We were counting up the number of losses we've had on the road in the other team's last at-bat. It's astronomical. Tonight was another one.”

Shigetoshi Hasegawa (4-3) received the win by getting the final out in the eighth inning. Eddie Guardado pitched the ninth for his 18th save in 23 opportunities.

”It was another good win,” Guardado said. ”We're having some fun right now and hopefully we can make it continue.”

Mariners starter Ryan Franklin allowed seven hits over six innings and left with the game tied at 2. The only time he was hit especially hard was Crosby's two-run homer over the A's bullpen in left field in the sixth.

”That was a mistake,” Franklin said. ”I tried to throw a curveball in the dirt and it didn't go where I wanted it to.”

Crosby's blast followed Scott Hatteberg's leadoff single and tied the game.

Franklin escaped a no-out, bases-loaded jam in the second without allowing a run. After Crosby and Erubiel Durazo led off with singles, Bobby Kielty reached on a fielding error by first baseman Bucky Jacobsen, loading the bases.

Franklin then struck out Eric Byrnes before getting Adam Melhuse to ground into an inning-ending double play.

In the first inning, Ichiro Suzuki and Randy Winn singled, advanced on a passed ball by Melhuse, and scored on Edgar Martinez's bloop single to left field.
