Ranger Suárez struck out a career-high 11 in seven shutout innings and backup catcher Rafael Marchán provided all the offense for Philadelphia with three RBIs and the Phillies held on for a 3-2 victory over the Washington Nationals on Sunday.
The Phillies have won six of seven and have a seven-game lead over the New York Mets in the NL East heading into their three-game series at Citi Field beginning Monday night.
Suarez (10-6) allowed only three hits. It was his second consecutive game with double-digit strikeouts after getting 10 against Seattle last week.
