Brandon Moss' homer boosts Oakland Athletics over Seattle Mariners OAKLAND, Calif., Aug. 20 (UPI) -- Brandon Moss belted a solo in the bottom of the ninth inning Monday, hoisting the Oakland Athletics over Seattle 2-1. The A's Jarrod Parker had thrown six innings of shutout ball before the Mariners tied it up 1-1 on a one-out RBI single from Kendrys Morales. It stayed knotted until one was out in the bottom of the ninth, when Moss connected on a pitch from Carter Capps (2-3) and sent it over the center field wall for his 19th round-tripper of the season. Parker (9-6) tamed the Mariners on one run in a complete-game victory, allowing eight hits with no walks while striking out eight as the second-place A's remained one-half game behind Texas atop the American League West. Aaron Harang pitched seven innings of one-run ball for Seattle, which fell in the opener of a three-game series.
