Nationals manager Martinez returning to dugout

Washington Nationals manager Dave Martinez will be back in the dugout Friday after missing three games following a heart procedure on Monday, the team announced.

Martinez, 54, had a minor cardiac catheterization in Washington after experiencing chest pains during Sunday's home game against the Atlanta Braves. He left in the sixth inning and was taken to a hospital.

"The bottom line is I feel good to go and I'm very happy and excited to rejoin the team," Martinez said. "It was hard to watch the games without being a part of it with the guys in the dugout."

Bench coach Chip Hale managed the team during Martinez's absence, with the Nationals winning one of three games in a series with the St. Louis Cardinals.

The Nationals have a 1-game lead over the Milwaukee Brewers for the top wild-card spot in the National League.

The Nationals open a three-series with the Marlins in Miami on Friday.
