Two people with knowledge of the situation said Sunday night that a deal to send star first baseman Adrian Gonzalez from San Diego to Boston was nearly complete.
The people spoke on condition of anonymity because the trade had not been announced.
One said the teams hoped to have a few final issues wrapped up by Monday. The other said a Sunday afternoon deadline had passed before the Red Sox and Gonzalez could agree on a contract extension, but the sides were believed to have agreed to continue to try to negotiate an extension.
The Padres would receive three of Boston's top prospects, plus a player to be determined.
Winter meetings. Though last-place Washington made quite a splash before baseball's winter meetings officially began, signing Jayson Werth, free agents Cliff Lee and Carl Crawford figure to keep interest in Lake Buena Vista, Fla., high this week.
After losing to Texas in the American League Championship Series, the New York Yankees figure to tangle with the Rangers again over Lee, trying to lure the ace lefthander away. Lee's decision could come this week.
Closer Rafael Soriano; sluggers Adrian Beltre, Paul Konerko, and Magglio Ordonez; and starting pitchers Carl Pavano, Kevin Millwood, and Chris Young were also among the free agents still in play.
The meetings typically produce trades. Last year, the big deal was a three-team swap that moved outfielder Curtis Granderson from Detroit to the Yankees.
The name of Kansas City pitcher Zack Greinke has been floated, and so have those of the Upton brothers, Tampa Bay outfielder B.J. and Arizona outfielder Justin.
