BOSTON — All-Star second baseman Dustin Pedroia is close to a contract that could keep him with the Boston Red Sox for his entire big league career.

A person with knowledge of the talks said Tuesday that Pedroia is in the process of agreeing to a deal adding $100 million over seven seasons through 2021.

The person spoke to The Associated Press on condition of anonymity because the agreement was not yet complete. The new deal was first reported by WEEI.

Pedroia is making $10 million this year and is guaranteed the same amount in 2014 as part of a $40.5 million, six-year contract that started in 2009.

That deal includes an $11 million club option for 2015 with a $500,000 buyout.

The 5-foot-8, 165-pound sparkplug was the AL Rookie of the Year in 2007 and AL MVP in 2008.

It’s important to Pedroia to finish his career in Boston. The deal would expire after he turns 38.

“It’s not official or anything, but, yeah, this is my home,” he said before Tuesday night’s game against the Tampa Bay Rays. “I love being here. I love my teammates. I love the city. So if (the deal is finalized), I’ll be pretty excited.”

Pedroia is a big reason for Boston’s success.

The Red Sox have a 1 1/2-game lead over the Rays in the AL East with a 61-41 record after winning just 69 games last season.

In 101 games, Pedroia is hitting .306 with six homers and 58 RBI. He made only two errors and missed just one game.

A new contract “is not going to change who I am or my role with this team,” he said. “My job is to still go out there and try to help us win a game every day and I’ll try to do all I can to make that happen.”

Pedroia might have received a better deal than the one that’s close to agreement if he had become a free agent after the 2014 or 2015 seasons.

“I don’t look at it like that,” he said. “I want to be at a place where it’s special to me and this place has been that.”

And he doesn’t expect a rich contract to change the way his teammates look at him.

“They still have to look down at me. I’m pretty short,” Pedroia joked, “but it’s a good feeling.”

In 957 games, Pedroia has a .303 career batting average, 96 homers and 467 RBI.

A second-round pick of the Red Sox in the 2004 amateur draft, Pedroia made his major league debut in August 2006. He hit .191 in 31 games that season then had his breakout season in 2007 when Boston won its second World Series championship in four years. He hit .317 with eight homers and 50 RBI.

He did even better in 2008 with a .326 average, 17 homers and 83 RBI, winning a Gold Glove and Silver Slugger award.

In 2011, Pedroia posted career highs of 21 homers and 91 RBI with a .307 average. He dipped slightly last year with a .290 average, 15 homers and 65 RBI as the Red Sox finished in last place in the AL East with a 69-93 record.

“I love being here,” Pedroia said. “I live and die by this team and it’s important to me to be here my whole time.”
