David Ortiz doubles in go-ahead run as Red Sox down Rays

BOSTON -- One of Bobby Valentine's first acts as Red Sox manager was to visit David Ortiz in the Dominican Republic and let him know how important it was to keep him on the team.

Now everybody is seeing that.

Ortiz, a free agent in the offseason, is off to one of the best starts of his career. On Sunday, the slugging designated hitter doubled in the go-ahead run for his seventh consecutive hit and Boston won its third straight game over the Tampa Bay Rays, 6-4.

"I definitely wanted to let him know that the new guy really wanted him," said Valentine, who was named manager Dec. 1. "I think that's basically all I said, that I always appreciated watching him from afar and I know how important he is to any team. And I wanted him on mine."

Ortiz agreed to a one-year, $14.575 million contract on Feb. 13 and brought a greater desire to play a leadership role.

"The best way to be a leader is come to the ballpark, prepare and be a professional, and we all know that's what Papi is," Boston's Adrian Gonzalez said.

One thing that hasn't changed is the left-handed Ortiz's ability to hit lefties. Last season, he batted .329 against them and .298 against righties. He went 3 for 4 on Sunday with all the hits against left-hander Matt Moore (0-1).

"Lefties are hittable, too. It all depends (on) what your mindset is," Ortiz said. "They throw the ball over the plate just like righties."

Boston, on a tear since a season-opening 1-5 road trip, can complete a series sweep in Monday's traditional Patriots' Day game that starts at 11:05 a.m. Last year the Red Sox were just 2-7 at home against the Rays.

"When you're playing a Tampa team that's touted to win 100 games in our division you must feel pretty good about it when you come out fighting like we did," Valentine said.

Ortiz is 16 for 36 in nine games this season.

"That's pretty impressive," Tampa Bay's Carlos Pena said. "It seems like he's squaring the ball up every time he's up."

Ortiz has struggled in recent years in April. He had 20 hits in 22 games in that month in 2009, eight in 16 games in 2010 and 23 in 25 games in 2011.

But on Sunday with the score tied 4-all in the sixth inning, he doubled home Kevin Youkilis, who had walked.

Ortiz went 4 for 5 with a homer and five RBIs in Saturday's 13-5 win. Then he doubled, singled and doubled in his first three at-bats on Sunday before grounding out to first to end the seventh.

Also in the seventh, Mike Aviles hit his second solo homer in two days from the leadoff spot. He moved there for the first time this season on Saturday when Jacoby Ellsbury went on the 15-day disabled list with a partially separated right shoulder.

"Matt got us deep into the game," Rays manager Joe Maddon said. "I thought he was still in good shape out there up until the end. They're just really hot right now."

Vicente Padilla (1-0) pitched 1 2/3 scoreless innings after Felix Doubront left the game following Luke Scott's leadoff homer that tied it in the sixth.

Alfredo Aceves pitched the ninth for his second save in three opportunities.

Moore gave up six runs on eight hits in 6 1/3 innings in the third regular-season start of his career.

The Red Sox scored first for the first time in the series with three runs in the second. Youkilis singled, Ortiz walked and Cody Ross hit his second homer in two days. They made it 4-0 in the fourth on Kelly Shoppach's RBI double.

Doubront, making just his fifth major league start, allowed four hits in four scoreless innings before struggling in the fifth, when he allowed three runs.

Chris Gimenez singled, Desmond Jennings doubled and Pena doubled in two runs after having his shot into the right-field stands ruled foul by video review. Evan Longoria made it 4-3 with a ground-rule double in the fifth and Scott's second homer in two days tied it.
