LAKE BUENA VISTA, Fla. -- Boston Red Sox manager Terry Francona called left fielder Carl Crawford a game-changer. Turns out he might have been guilty of understatement.

Between the multitalented Crawford, who a source confirmed came to terms Wednesday night on a seven-year, $142 million deal with Boston, and slugging first baseman Adrian Gonzalez, acquired by trade last weekend from San Diego and in line for his own seven-year deal for an estimated $154 million, the Red Sox appear set for the next decade.

Crawford passed his physical on Friday, a team source confirmed, and the Red Sox have scheduled a 10 a.m. ET Saturday news conference to announce his signing.

"Adrian already heard about Carl," Gonzalez's agent, John Boggs, e-mailed Wednesday night. "He's very happy."

A team that has often complained about the spending habits of the New York Yankees, who two years ago swooped in and outbid Boston for Mark Teixeira, has abandoned fiscal restraint by making Crawford the first player in Red Sox history with a contract with an average annual value in excess of $20 million.

"Great move. Great player," said Yankees general manager Brian Cashman, for whom signing free-agent left-hander Cliff Lee now takes on even greater urgency. "Boston's got the money and they had a need."

Crawford also becomes the first Red Sox player since John W. Henry and Tom Werner purchased the team in 2002 to be given a contract of seven years. General manager Theo Epstein evidently made a persuasive case to Henry late in the process to do so.

"When things come together the way we hope and expect, we'll be real satisfied," Epstein said Thursday. "You go into every winter with a Plan A, and sometimes it's hard to pull that off, then you move on to Plan B and C.

"Adding an impact player was very important to where we were for the short and long term, and adding two -- as long as they were the right players for the right spots in the right situation -- would be even better."

Without mentioning names, Epstein made it clear he had accomplished exactly what he wanted to in the last few days.

"We did this objectively over months and months and months," Epstein said. "We realized there was a shot if things came together the right way, we could be pretty aggressive on a couple players we really liked."

The agreement with Crawford was first reported by The Boston Globe on its website.

Crawford received four offers, according to a source close to the negotiations, with the Red Sox and Angels making the most substantial offers. The Angels made an offer that was termed extremely competitive with Boston's offer.

"It was a very difficult decision for Carl," the source said. "In the end, it came down to his desire to become a member of the Red Sox, move to Boston and the ability to win."

The Angels' offer to Crawford was six years, $108 million, league sources told ESPN The Magazine's Buster Olney on Thursday.

The Red Sox had been aggressive in their pursuit of Crawford and Jayson Werth, the other elite outfielder eligible for free agency. Last week, Epstein flew to Houston to meet with Crawford, then met with Werth in Chicago.

But Sunday night, Werth was eliminated as a potential target when the Washington Nationals stunned their peers by signing the 31-year-old outfielder to a seven-year, $126 million deal.
