Murphy, 33, had microfracture surgery back in October on his right knee. His return will be a boon for the Nationals. Last season, he hit .322/.384/.543 with 23 home runs and 93 RBI in 593 plate appearances, helping the club reach the postseason for a second consecutive season.
Howie Kendrick mostly handled second base until he suffered an Achilles injury a month ago. Wilmer Difo, with an unimpressive .676 OPS, had been the regular second baseman since. Difo will cede second base to Murphy likely after the Nats’ two road interleague series with the Yankees and Blue Jays.
