What is the most runs an MLB team has come back from with two outs and nobody on in the ninth inning?
Seven teams have staged 7 run rallies in the ninth but with no-one on and 2 out who knows?
I thought this game

was it, but the Giants had a runner on first with two outs when they started their rally.
Eight. The Cleveland Blues (later Indians) defeated the Washington Senators, 14-13, after trailing 13-5 with two out and nobody on in the bottom of the 9th inning on May 23, 1901.
Thanks, jklann.
I din’t know how to research this question but I knew this board could answer anything. I appreciate the details. 
Eight runs only makes it 13-13. Did they win the game in extra innings?

At Cleveland’s League Park, the Blues score a major-league record nine runs with two outs in the 9th inning to defeat the Washington Nationals 14-13. Cleveland is down to one strike, on Jack McCarthy, but they put the next ten men on base, winning the game on an error. Winning pitcher Bill Hoffer, who had given up the 13 runs, is carried off the field by the delirious crowd. Patton and Lee pitch for Washington. The scoring (as noted by Bill Kirwin) occurs as follows: Hoffer K, Pickering ground out, McCarthy singles, Bradley singles, LaChance with two strikes on him) singles scoring McCarthy, Wood is hit by pitch, Scheibeck doubles (Patton, replaced by Lee), Egan walks, Beck (batting for Hoffer) doubles, Pickering singles Beck home to tie the game, and then moves to 2B on a passed ball. Mc Carthy, who started the whole thing, singles him home for the victory.
