Second baseman Daniel Murphy agrees to a three-year deal with the Washington Nationals

Second baseman Daniel Murphy and the Washington Nationals agreed to a three-year contract, a person familiar with the negotiations told the Associated Press.

The person spoke on condition of anonymity Thursday night because the agreement was subject to a successful physical.

Drafted by the Mets in 2006, the 30-year-old Murphy starred in October when he homered in a record six straight postseason games and was voted the most valuable player in the Mets’ National League Championship Series victory over the Chicago Cubs. But he made key errors in the fourth and fifth games of New York’s five-game World Series loss to the Kansas City Royals.

Murphy hit .281 this season with a career-best 14 homers and 73 runs batted in. In seven seasons, all with the Mets, he has a .288 average with 62 homers and 402 RBIs.

Murphy became a free agent after the season and rejected the Mets’ $15.8-million qualifying offer.

Washington loses its first-round draft pick, the 16th overall, and the Mets gain a compensation-round pick. The Nationals will have compensation-round picks for Jordan Zimmermann and Ian Desmond.

New York already has replaced Murphy with free-agent second baseman Asdrubal Cabrera.

Etc.

A woman charged with shaking down New York Yankees General Manager Brian Cashman pleaded guilty to extortion, perjury and criminal impersonation. Louise Neathway entered a type of guilty plea Wednesday that acknowledges sufficient evidence for conviction but doesn’t admit guilt. She was sentenced to five years’ probation.

The 39-year-old Neathway is also called Louise Meanwell. She was charged in 2012 with harassing Cashman and extorting $6,000 by threatening to damage his reputation. She said the two had a consensual affair. Cashman was then married.
