Bill Mueller
The Red Sox trailed 4–3 in the bottom of the ninth inning of Game 4. But the team tied the game with a walk by Kevin Millar and a stolen base by pinch-runner Dave Roberts, followed by an RBI single against Yankee closer Mariano Rivera by third baseman Bill Mueller, and won on a two-run home run in the 12th inning by David Ortiz. The Red Sox won the next three games to become the first MLB team to win a seven-game postseason series after losing the first three games.
