Ian Browne, MLB.com:
By delivering what was easily their biggest win of the season, a tense 5-4 victory over the Blue Jays, the Red Sox can now clinch a tie in the American League East by taking two out of three from the Yankees this weekend. They can win the division outright with a sweep.
To get to that point, the Red Sox needed the latest batch of magic from David Ortiz, who tied it with a homer in the eighth inning and then won it in the bottom of the ninth with a walk-off single to left field, setting up a mob scene of white jerseys on the right side of the infield.
Yet again, Ortiz delivered with the game -- and perhaps the season -- on the line.
