NASHVILLE, Tenn. — The Boston Red Sox kept the cash freely flowing, this time revving their lineup with Shane Victorino, while the well-armed Washington Nationals neared a deal with Dan Haren at baseball’s winter meetings Tuesday.

In the first two trades of the week, Colorado got effective reliever Wilton Lopez and a player to be named from Houston for young right-handers Alex White and Alex Gillingham, and Miami sent recently acquired shortstop Yunel Escobar to Tampa Bay.

Cy Young Award winner R.A. Dickey of the New York Mets is still the prime trade target, with Boston in the mix for him, too.

Josh Hamilton remains the top free agent amid speculation the slugger will re-sign with Texas. Ace pitcher Zack Greinke also is available, with the Los Angeles Dodgers and the Rangers very interested.

Dodgers manager Don Mattingly said he’s been involved in the pursuit of one free agent. He didn’t disclose who it was, but seemed to be enjoying this week’s developments.

“It’s like a smorgasbord of baseball. It’s been good,” Mattingly said.

Boston has been the busiest team this offseason, by far. A day after giving All-Star bat Mike Napoli a $39 million, three-year deal, the Red Sox lured Victorino with the exact same contract terms.

The Red Sox are coming off their worst season since 1965 and trying to reshape the roster. The 32-year-old Victorino is a two-time All-Star and three-time Gold Glove winner who stole a career-high 39 bases for Philadelphia and the Dodgers last season.

Recently, the Red Sox added Jonny Gomes and David Ross.

Victorino’s arrival could also lead to a trade of center fielder Jacoby Ellsbury, coming off a down, injury-interrupted season.

The Nationals and Haren are close to completing a one-year deal for $13 million, a person familiar with the talks told The Associated Press. The person spoke under condition of anonymity because no deal was announced.

Washington had the best record in the majors last season.
