Buchholz's beginnings haven't been good, either. He allowed four runs in each first inning of his other two starts. On Friday, he gave up only one run in the opening inning. But by the time he left after walking Granderson to lead off the seventh, he had allowed six runs on nine hits and two walks with just two strikeouts.
The Yankees led 1-0 three batters into the game. Jeter reached on an error by second baseman Dustin Pedroia, who lost his popup in the sun. Jeter moved up on a wild pitch and scored on Rodriguez's single.
They needed only three batters again to take a 3-0 lead in the second. Swisher led off with a homer, Raul Ibanez grounded out and Chavez drove an 0-2 pitch into Boston's bullpen in right-center. Chavez had only six at-bats before Friday, when he played third base while Rodriguez was the designated hitter.
"''I relish anytime I get put in the lineup," Chavez said.
David Ortiz cut it to 3-1 leading off the second with his second homer. The Yankees stretched their lead to 5-1 on leadoff homers by Chavez in the fourth and Rodriguez in the fifth. They were the second homers of the year for both.
Rodriguez needs 29 homers to catch Willie Mays for fourth place.
"We have much bigger goals around here than trying to chase history," he said, "but, obviously, when you talk about a name like Willie Mays ... when the time comes, that's a pretty great name."
The Red Sox made it 5-2 in the fifth when Cody Ross doubled and Mike Aviles was credited with a double when Swisher lost his fly ball to right in the sun. Martin homered in the sixth.
