SEATTLE - Brian Roberts homered to open the eighth inning, capping Baltimore's rally from a five-run deficit, and the Orioles beat Seattle 8-7 on Thursday night for their sixth win in seven games against the Mariners this season.

Roberts jumped on a 1-0 pitch from reliever Sean Green (1-1), for his second homer of the season, capping a wild night where both Seattle and Baltimore saw leads evaporate and each team used six pitchers.

Baltimore Orioles' Adam Jones doubles against the Seattle Mariners in the third inning.

Chad Bradford (2-1) got the final out of the seventh and worked the eighth to get the win. Former Seattle reliever George Sherrill pitched the ninth for his eighth save, five against Seattle.

Yuniesky Betancourt led off the ninth with a single, but Sherrill got Ichiro Suzuki to ground into a rare double play and Jose Lopez grounded out to end it.

Seattle led 5-0 after battering Baltimore starter Adam Loewen for three innings. But that lead was gone in the seventh when the Orioles scored four times off Seattle's bullpen. Kevin Millar had a sacrifice fly, Aubrey Huff hit an RBI single and the rally was capped by former Mariners' prospect Adam Jones ripping a two-out, two-run double off the left field wall off Mark Lowe. Jones barely missed a grand slam, but still gave Baltimore a 7-5 lead.

Jones, who never got an opportunity to completely display his potential in Seattle, had two doubles and three RBIs against his former team.

The lead was short-lived. Betancourt opened the seventh with a single off reliever Matt Albers and Baltimore manager Dave Trembley brought in lefty Jamie Walker to face Suzuki. Ahead in the count 2-1, Suzuki hit a two-run homer to right pulling Seattle even at 7-all.

Roberts then homered in the top of the eighth, in almost the same spot at Suzuki. It was the second straight night Seattle's bullpen gave up a tie-breaking, eighth-inning homer to the Orioles. Nick Markakis homered off Ryan Rowland-Smith to give Baltimore a 3-2 win on Wednesday night.

Jay Payton also homered for Baltimore, a solo shot in the fourth.

Baltimore's late rally kept Loewen from picking up his second loss of the season, although his future in the Orioles' rotation is sure to be debated.

Loewen, who missed most of the 2007 season with an elbow injury, has yet to show any signs of recovering the form that made him a first-round draft pick in 2002.

Loewen had a 9.00 ERA in the first three innings of his starts. That trend continued against Seattle, as Loewen gave up Adrian Beltre's solo homer in the second before falling apart in the third, allowing four runs.

Lopez and Raul Ibanez hit sacrifice flies, before Jose Vidro capped the inning with a ground-rule double to deep center field, scoring two.

Seattle starter Jarrod Washburn struggled as well, barely lasting five innings. He gave up two runs and six hits and walked three, throwing 53 strikes in 97 pitches.

Seattle manager John McLaren was ejected in the seventh inning after twice arguing with home plate umpire Casey Moser.

With no outs, Seattle reliever Arthur Rhodes walked Markakis to load the bases. McLaren went to pull Rhodes, but on his way to the mound, detoured to home plate to talk with Moser. The two exchanged words, but no action was taken. McLaren went back to home plate again after Rhodes left, this time getting tossed by Moser and becoming extremely animated. It was McLaren's first ejection of the season.
