SEATTLE (AP) - The Seattle Mariners made two trades over the weekend, including a seven-player, three-team deal right before the non-waiver trade deadline. They're hoping the moves will lead to a brighter future, because the present is an ugly mess.

The woeful Mariners managed just six hits against Jeremy Hellickson and two relievers Sunday, falling 8-1 to the Tampa Bay Rays.

Seattle had a franchise-record 17-game losing streak during a 6-20 July, tying the franchise low set just last season for the fewest wins in the month. The Mariners have lost 22 of their past 29 games overall.

The epic slide led to a sell-off this weekend.

The Mariners shipped starter Doug Fister and reliever David Pauley to Detroit on Saturday morning for outfielder Casper Wells, infielder Francisco Martinez, left-hander Charlie Furbush and a player to be named. They traded left-hander Erik Bedard and a minor league pitcher to Boston in a three-team deal Sunday, netting a pair of minor league outfielders.

"It still goes back to adding talent," Seattle general manager Jack Zduriencik said. "We got back pieces that we need to help us as we move forward. Certainly, we were focusing on acquiring offensive players."

The Red Sox, whose deal for Oakland pitcher Rich Harden fell apart late Saturday night, also got right-hander Josh Fields, a 2008 first-round draft pick of the Mariners.

Boston first sent minor league right-handers Stephen Fife and Juan Rodriguez and catcher Tim Federowicz to the Dodgers in exchange for outfielder Trayvon Robinson and then traded Robinson to Seattle with minor league outfielder Chih-Hsien Chiang in exchange for Bedard and Fields.

The Mariners have the majors' worst batting average at .225 with only 65 home runs. They also weren't much better last season.

"We made some deals that we feel can help us now and in the future," Mariners manager Eric Wedge said. "We move forward from there.

"We want to build something that Seattle and the fans from year to year can count on."

Hellickson allowed one run and five hits in seven-plus innings to become the first AL rookie with 10 wins. He is the quickest Tampa Bay pitcher to 10 wins since Rolando Arroyo on June 27, 1998.

Hellickson carried a no-hitter into the sixth but Chone Figgins, batting .184, opened with a single to center and Franklin Gutierrez followed with another single. Hellickson retired the next three batters on a flyout and two foulouts.

The Mariners finally scored in the seventh, but it wasn't pretty. Mike Carp and Olivo opened with singles. Adam Kennedy forced Olivo at second, before Wells hit a blooper that dropped into shallow right center.

Carp scored but Kennedy, unsure whether it would drop, was thrown out scrambling for second.

Wells picked up an RBI on the fielder's choice, and singled in the ninth for his first hit with Seattle.

"I was using Adam Moore's bats the first couple at-bats and I didn't like the weight," said Wells, whose own bats didn't arrive in time from Detroit.

Wells then used rookie pitcher Michael Pineda's bat for final two at-bats, with both dropping in the outfield, just one for a hit.

Furbush entered the game in the eighth and gave up a home run to Sean Rodriguez on a 1-2 pitch.

"I tried to go in off the plate, just get it in, and it wasn't in enough," Furbush said. "The guy's going to hit that pitch."

Wedge said Furbush "has a good arm. That was a fastball up for the home run. But it's good to get the first one out of the way."

Fields, 25, the 20th player taken in the 2008 draft out of Georgia, was 2-1 with a 2.77 ERA for Double-A Jackson and 0-0 with a 6.23 ERA in nine games for Triple-A Tacoma.

"We've been talking Chiang for a while. Robinson came in a couple hours (before the deadline) as we discussed it," Zduriencik said. "He was the guy we settled on."

The Mariners have been struggling offensively - the Mariners designated Jack Cust for assignment Friday - and both 23-year-old prospects have power potential.

Robinson is hitting .293 with 26 home runs and 71 RBI for Triple-A Albuquerque.

"He'll go to Tacoma and we'll watch him there," said Zduriencik, when asked if Robinson was close to a promotion. "We'll see what happens."

Chiang is hitting .338 with 36 doubles, 18 home runs and 76 RBI in 87 games for Double-A Portland.

NOTES: Wells is the first player named Casper to reach the majors.
