SEATTLE -- Cliff Pennington didn't wait for something better to come, taking advantage of a situation that has eluded Oakland during its recent scoring struggles.
One pitch after a potential inning-ending diving catch became an RBI single for Kevin Kouzmanoff, Pennington hit a two-run homer, part of Oakland's season-high scoring output in a 9-1 win over the Seattle Mariners on Saturday night.
Kouzmanoff and Pennington -- hitting eighth and ninth in the A's order -- provided the big blows with each hitting homers in key moments.
"It's fun because we're next to each other the whole game," Pennington said. "When we're both getting hits, we talk to each other. When we're not, neither one of us want to talk."
But the biggest breakthrough for Oakland came in the third when Coco Crisp ripped the first of his two RBI doubles that snapped a 20-inning scoreless streak for the A's.
Crisp's two-out double into the right-center field gap off Seattle starter Jason Vargas (0-2) scored Mark Ellis with the A's first run since the ninth inning on Wednesday against Boston. The A's were shutout in the first two games of this series having to face Felix Hernandez and promising rookie Michael Pineda, the first time Oakland was held scoreless in consecutive games since May 2008 and prompting plenty of questions about an offense that was already lagging toward the bottom of the American League.
There wasn't going to be a third straight shutout and plenty of support for Trevor Cahill (3-0) to remain undefeated.
"This is a good offense and we're going to score runs. It's just a week where we had everybody not swinging it well at the same time. Normally you have three or four guys hot and three or four guys not and we just kind of were not at the same time," Pennington said. "We're not too worried about it. Everybody is going to do what they do."
Oakland didn't just sit on a 4-1 lead thanks to Pennington's first homer of the season in the fourth, a two-run shot into the A's bullpen in left field. Oakland added five in the sixth inning, knocking Vargas from the game. The A's sent 10 batters to the plate, highlighted by Kouzmanoff waiting on reliever Josh Lueke's 1-2 breaking ball and hitting it just over the hand-operated scoreboard down the left field line for his second homer of the season.
Kouzmanoff finished with four RBIs -- nearly doubling his season total entering the night. He got lucky in the fourth when his line drive to center field was misplayed on a diving attempt by Michael Saunders, who was in position on the dive to make an inning-ending grab, only to see the ball glance off the top of his mitt. It was ruled a single that scored Kurt Suzuki and Pennington made Seattle pay.
"Our energy level has been good, it just seems like when you're not getting hits or runs it looks down, but if you're in there it was pretty much the same," A's manager Bob Geren said. "The guys had more smiles because they were having some success, but the energy level has been good all year."
Crisp added another RBI double in the sixth inning and finished with three hits, after going hitless in his previous nine at-bats, and Conor Jackson had an RBI single.
That was more than Cahill needed, even though the right-hander wasn't at his best. Cahill escaped trouble in each of the first two innings, then settled down to retire 15 of his final 17 batters. He struck out two and walked only one.
"For a catcher, that is not an easy play to make," Geren said.
Even after Figgins was cut down, Seattle had runners on second and third, but Cahill got Saunders to ground out to end the inning.
Meanwhile, Vargas saw his losing streak extended to nine straight decisions dating back to Aug. 14, 2010.
"There needs to be a little more sense of urgency out there for me," Vargas said.
