A's vs. Mariners online LIVE stream: Watch as two aces go at it one last time this season and if Oakland wants any chance at the best record in the American League, they'd have to win these last three games.

The A's vs. Mariners game could be a pitching matchup to possibly determine the Cy-Young award winner in the A.L. Watch the live stream online as Bartolo Colon pitches for Oakland and Felix Hernandez for Seattle.

Watch the live stream online at 7:10 PT in Seattle for the A's vs. Mariners. Bartolo Colon, (RHP 17-6, 2.64 ERA) will pitch against Felix Hernandez (RHP 12-9, 2.99 ERA).

If Hernandez pitches 1 2/3 innings, he will have reached 200 innings for the sixth straight season. Colon on the other hand is having a comeback season and almost a 20-game winner.  

The A's have lost more games to the Mariners than any other opponent, compiling a 6-10 record against them heading into the weekend.

"I think, record-wise, they've played us as tough as anybody," A's manager Bob Melvin said. "It's been a team that's matched well against us, and we're going to have to play good to beat them. They've been a challenge for us."

Maintaining their lead on the Tigers for home field in the AL Division Series is still in question as Detroit is only a game back. The Tigers play a three-game set in Miami against the Marlins.
