Daniel Murphy passed his physical on Wednesday, completing his three-year, $37.5 million deal, and he will be introduced at a 12:15 p.m. press conference Thursday at Nationals Park. He is expected to primarily man second base but he can also play first and third, and even left field in a pinch. Murphy, the Mets’ playoff slugging hero, provides a much-needed left-handed presence for the once right-handed-heavy Nationals lineup.

More to come from Murphy’s news conference Thursday, why he chose the Nationals despite a four-year offer from another team and how he fits into the organization. Even though Murphy’s average annual value is $12.5 million, he will make only $8 million in 2016. The higher yearly salaries come in 2017 and 2018, with deferred money, when the Nationals have fewer payroll commitments.

In order to make room for Murphy on the 40-man roster, the Nationals designated right-handed reliever Erik Davis for assignment.

The Nationals also announced the addition of infielder Stephen Drew on Wednesday afternoon. He passed his physical, which was earlier this week, so his one-year, $3-million deal is now official. His contract also includes $1.25 million in incentives based on games played. In order to make room for Drew on the roster, right-handed pitcher Taylor Hill was designated for assignment.
