OXON HILL, Md. — The champion Chicago Cubs filled their only real need, getting All-Star reliever Wade Davis. He’ll take the spot of closer Aroldis Chapman, who locked down a spot by returning to the New York Yankees with a whopping $86 million deal.

As for the Washington Nationals, well, they opened quite a debate Wednesday by trading not one, not two, but three talented, young pitchers for White Sox outfielder Adam Eaton.

And as the winter meetings wound down, the Yankees struck just before midnight. They reached a five-year deal with Chapman, according to a person familiar with the contract. The person spoke on condition of anonymity because the contract was still pending a physical — it would be the richest deal ever for a reliever, shattering the $62 million, five-year pact Mark Melancon got from San Francisco just a couple days ago.

Chapman was acquired by New York from the Cincinnati Reds last offseason, then missed the first 29 games of the season due to a domestic violence suspension from Major League Baseball. The Cuban was traded to the Chicago Cubs in late July and helped them win the World Series, becoming a free agent when it was over.

Ian Desmond also wound up in a new spot, reaching a $70 million agreement with Colorado on the last full day of baseball’s annual gathering. The session ends this morning after the Rule 5 draft.

“The free agent market and the trade markets have both been a little slow,” Mets general manager Sandy Alderson said earlier in the day. “Things are picking up a little bit.”

Closer Kenley Jansen was still in play, and Pittsburgh didn’t trade — not yet, anyway — outfielder Andrew McCutchen.

To get a closer who’s been dominant for the last three years, the Cubs sent outfielder Jorge Soler to Kansas City for Davis.
