Oakland, CA (Sports Network) - Brandon Moss belted a solo home run off Carter Capps in the ninth inning to send the Oakland Athletics past the Seattle Mariners, 2-1, in the opener of a three-game AL West series.
The pitchers' duel was decided on a one-out, 2-1 fastball from Capps (2-3) that Moss sent to straightaway center for his 19th home run of the year.
The blast secured a win for Jarrod Parker (9-6), who tossed a complete game for the first time and stayed unbeaten in his last 15 starts. Parker scattered eight hits and allowed one run while striking out eight with no walks.
Seattle starter Aaron Harang did not factor in the decision despite holding the A's to one run on five hits over seven innings.
Oakland has won four of its last five while Seattle fell to 3-4 on its nine- game road trip.
