The Boston Red Sox continued their fine September form by sealing a clean sweep over the Yankees to take control of the AL East.
The Red Sox took control of the third and final game in the series thanks largely to Mike Napoli's three run homer in the first innings.
That gave Clay Buchholz the platform to shut out the Yankees from the second innings to the ninth, easing Boston to a 9-2 win.
In just his second start since emerging off the disabled list, Buchholz allowed only one unearned run whilst giving four walks and striking out three.
"It's fun to play ball when things are going right. That's how this team's been all year," said Buchholz to reporters, who spent three months out with a strained neck. "To run back out there two starts in a row, that's what I want to do. That's where I want to be."
The win effectively rules the Yankees out of the race for the AL East - a disappointment considering they are the reigning champions.
Boston take control at the top of the table after winning 10 of their last 12 games and are now leading second placed Tampa Bay by nine and a half games.
It was also the sixth win the Red Sox have enjoyed over their New York rivals in seven ties played over an 11 day period.
"It's not just one team," said Red Sox catcher Jarrod Saltalamacchia to reporters, who scored a run on a double steal. "It's how we play. We want to win every game. We never settle for what (the lead) is. It's 'Go for the next one."
Boston now lie four wins away from clinching just its second division title since 1995 whilst the Yankees are 12 and a half games away from Boston with just 12 to play.
