PHOENIX (AP) – Mike Lowell’s pinch-hit sacrifice fly scored David Ortiz in the 10th inning and lifted the Boston Red Sox to a 4-3 victory over the Arizona Diamondbacks on Saturday night.

Jason Varitek homered, doubled and drove in three runs for the Red Sox, who won their third straight to remain 10 games ahead of the New York Yankees in the AL East.

Juan Cruz (2-1) walked Ortiz to open the 10th, and Kevin Youkilis and J.D. Drew both singled to load the bases. Cruz struck out Varitek before Lowell lifted a high fly to right that Carlos Quentin caught, but his throw home was well wide of the plate.

The Diamondbacks appealed at third, saying Ortiz left for home early, but were denied.

Hideki Okajima (2-0) pitched two innings, allowing a walk and striking out one, for the win in front of 49,826, the largest paid crowd in Chase Field history.

Jonathan Papelbon, making his first appearance in a week, allowed two baserunners in the 10th before finishing for his 14th save in 15 attempts.

Youkilis walked to lead off the eighth against Brandon Lyon and was forced at second on J.D. Drew’s grounder to first. Varitek followed with a double to the wall in left-center, scoring Drew to tie it at 3.

Varitek’s sixth-inning homer, his seventh, had pulled Boston within 3-2 after Arizona opened a 3-0 lead after four innings.

Stephen Drew homered for the Diamondbacks, who lost their third straight and remained a game behind San Diego in the NL West.

Mark Reynolds led off the fourth with a double down the left-field line off Julian Tavarez (3-5) and Drew followed with a line-drive homer just over brother J.D.’s head and the right-field fence to give the Diamondbacks a 3-0 lead.

Micah Owings pitched out of trouble for much of the night and allowed two runs and seven hits over six innings.

Stephen Drew’s hard slide at second after a leadoff single broke up a possible double play and allowed Quentin to reach on a fielder’s choice. Miguel Montero doubled just inside the right-field line as Quentin broke for second, and the right fielder scored easily for a 1-0 lead.

Tavarez allowed three runs on six hits with a walk and five strikeouts.
