Sam Fuld followed with a line drive to center field that got under the glove of center fielder Abraham Almonte allowing Fuld to round the bases attempting an inside-the-park home run.
A great recovery and subsequent relay throw to catcher Mike Zunino nailed Fuld at the plate that temporarily preserved the Mariner, 2-1 lead.
Oakland tied the game in the eighth. After back-to-back walks to Coco Crisp and Josh Donaldson, Jed Lowrie grounded into a 4-6-3 double play that left Crisp on third base for Yoenis Cespedes’ RBI game-tying triple.
Both bullpens held the teams scoreless until the 12th inning when Seattle’s Hector Noesi’s second pitch to Coco Crisp sailed over the right field wall for the Athletics’ 3-2 extra-inning victory.
“I was just going up there to swing as hard as I could,” Crisp said afterwards.
“With that approach, 9 times out of 10 you wind up with a strikeout, this time was the one time it worked out.”
Oakland’s Jesse Chavez pitched 6 innings allowing 5 hits and 2 runs before yielding to Fernando Abad, Sean Doolittle, Luke Gregerson and eventual winning pitcher, Drew Pomeranz.
