Watch: Mariners stage largest comeback in team history

You can't keep the Seattle Mariners down.

Facing a 12-2 deficit in San Diego after five innings, the M's staged an epic two-inning rally with five runs in the sixth and nine runs in the seventh to take a stunning 16-13 victory over the Padres.

It started with a five-run sixth inning that was led by Kyle Seager's two-run double and Dae-Ho Lee's mammoth three-run homer that landed in the Western Metal Supply building.

One inning later, the Mariners cycled through three helpless Padres relievers and made their defense leak like a colander. All nine seventh-inning runs scored by the Mariners came on seven consecutive two-out singles. Some clanked off gloves, some found holes, and some were solid line drives to the outfield. The winning run came home courtesy of shortstop Shawn O'Malley, who had only entered the game on a double-switch in the top of the inning.

"You don't see that very often," Seager told reporters of the seven straight singles. "That doesn't happen. That was just unbelievable and something I've never been a part of."

Thirteen Mariners hitters had batted by the time Padres left-hander Matt Thornton mercifully ended the inning. Every one of those 13, save for Nelson Cruz, reached base at least once in the seventh.

The stunning 10-run turnaround is the largest deficit overcome in Mariners franchise history, surpassing their eight-run comeback against the California Angels on April 15, 1996.
