LAKE BUENA VISTA, Fla. – Theo Epstein played it coy. He wouldn’t discuss Carl Crawford by name and yet still made it clear that the Boston Red Sox had accomplished their goal of a major retooling by adding a second impact bat to join the newly acquired Adrian Gonzalez.

“We did this objectively over months and months and months,” the Red Sox general manager said Thursday. “We realized there was a shot if things came together the right way, and we could be pretty aggressive on a couple of players we really liked.”

Crawford reached a preliminary agreement with the Red Sox on a $142 million, seven-year contract late Wednesday night. The deal, subject to his passing a physical, should be finalized within days.

“If things come together the way we hope and expect, we’ll be really satisfied,” Epstein said. “You go into every winter with a Plan A, and sometimes it’s hard to pull that off and you move on to Plan B and C. I think adding an impact player was very important for where we were in the short-, medium- and long-term, and adding two, as long as they were the right players in the right spots in the right situations, would be even better.”

A four-time All-Star and a first-time Gold Glove winner this year, Crawford hit .307 for Tampa Bay, and set career highs with 19 homers and 90 RBI. A four-time stolen-base champion, he also swiped 47 bases and led the AL with 13 triples.

Boston replaced the offense lost by the departures of Victor Martinez and Adrian Beltre with the bats of the 29-year-old Crawford and the 28-year-old Gonzalez, who is thought to have agreed to a long-term contract that won’t be finalized until after opening day, a move that lowers Boston’s 2011 payroll for luxury-tax purposes.

“Getting players in their primes or in the early parts of their primes I think is very important,” Epstein said. “If you’re going to sign a long-term contract, you want to make sure it starts at the right age and hopefully ends still at a reasonable age. Most elite position players sign through age 36. So if you can get a player signed just through 35, I know it sounds silly, but that might be a small victory in and of itself, capturing more of a player’s prime years.”

Boston can explore trading excess outfield depth for bullpen help. Crawford figures to play left field in an outfield that currently projects to have Mike Cameron or Jacoby Ellsbury in center and J.D. Drew in right.

When Boston won World Series titles in 2004 and 2007, the offense was led by Manny Ramirez and David Ortiz.

“We’ve gotten away from that over the last couple of years, away from that core belief that a long-term contract is a significant investment, is best made in a position player, is safest in a position player, more impact in a position player,” Epstein said. “A truly elite position player in his prime is a sound investment, if it’s the right player, it’s the right makeup, the right health and the right ability.”

New York had been speaking with Crawford. Yankees General Manager Brian Cashman said he never made an offer.

“It’s a great player, a great move,” Cashman said. “They’ve had two huge acquisitions. They’re loading up like they always do, and this is even more significant than a typical Red Sox reload.”

The Los Angeles Angels had been considered the front-runner to land Crawford. But other teams usually can’t keep up financially with the Red Sox and Yankees.

“I think you compete by developing and scouting. You do those things well, you can compete,” Angels General Manager Tony Reagins said. “They have revenue streams that a number of other clubs don’t have. But they conduct business in the manner that they feel appropriate and you can’t fault them for that.”
