Dave Martinez returns to Nats days after heart procedure

Washington Nationals skipper Dave Martinez is returning to the team to manage Friday's game against the Miami Marlins, the club announced.

Martinez underwent a minor heart procedure Monday after feeling chest pains during Sunday's game.

The 54-year-old was released from the hospital Tuesday and will not require any further cardiac treatment in the near future, according to Jesse Dougherty of The Washington Post.

Martinez rejoins a Nats squad clinging to the National League's top wild-card spot; Washington holds a single-game lead over the Milwaukee Brewers and sits two games above the Chicago Cubs.
