If you were able to watch the A's game Wednesday, you witnessed history. The A's only collected two hits -- they were both home runs. According to our A's historian David Feldman, that is the first time in Oakland A's history that has happened. The two homers were enough to give the A's a 2-1 win in Seattle. Jarrod Parker shut down the Mariners to earn his fourth win, and Ryan Cook got his sixth save.Starting Pitching ReportParker struck out a career-high nine hitters. His previous high came on May 23 against the Angels when he struck out eighth. He threw 104 pitches over seven innings. He only allowed one run, and it is the sixth time in his last seven starts that he has allowed one run or fewer.His only mistake came when John Jaso ripped a first-pitch fastball over the right field fence for a solo home run. After the homer, he ended up walking back-to-back hitters, then they advanced to second and third on a wild pitch. Parker ended up striking out Ichiro Suzuki swinging to escape the jam. The pitch he struck out Ichiro on was way above the strike zone.Parker's Achilles heel has been putting runners on base. He walked four batters on Wednesday and has 36 walks this season, which is the most by any A's pitcher.Bullpen ReportRyan Cook pitched the ninth inning for his sixth save. He got Jaso to ground out, then Brandon Inge made an error allowing Justin Smoak to reach base. Cook then fell behind 3-0 to Dustin Ackley before battling back and getting him to pop out in left field foul territory for the second out. Cook then hit Brendan Ryan with a 96-mph fastball. With runners on first and second he faced Ichiro, who struck out swinging to end the game.Grant Balfour pitched the eighth inning. He gave up a double to Kyle Seager but escaped unscathed. He hasn't allowed a run in his past 11.2 innings pitched.At the PlateCoco Crisp lead off the game with a home run to right field. It was a hanging pitch that was belt-high. The ball barely cleared the fence, landing in the front row of the right field bleachers.After Crisp's homer, Kevin Millwood had retired eight-straight A's hitters before being pulled from the game in the top of the third, after aggravating a groin injury. Hisashi Iwakuma entered in relief. The A's won the negotiating rights with Iwakuma prior to the 2010 season, but they couldn't strike a deal when Iwakuma's agent Don Nomura reportedly asked for "Zito-type money."The A's hadn't recorded a hit since Crisp's leadoff homer, until Yoenis Cespedes stepped to the plate in the seventh inning. He hammered a change-up for his ninth home run of the season, and his fifth against the Mariners, giving the A's a 2-1 lead.Both Brandon Inge and Brandon Moss have gone ice cold. Inge is 6-for-41 with 15 strikeouts over his last 12 games, and Moss has 16 strikeouts over that span.Up NextThe A's head to Arlington, Texas to take on the first place Rangers. Tyson Ross (2-7, 6.02 ERA) takes on Scott Feldman (1-6, 6.00 ERA). Feldman gave up eight runs in Oakland on June 4. He has rebounded nicely, allowing a total of eight runs in his last three starts since then.
