Jason Werth had four hits and two RBI's as the Washington Nationals dealt the New York Mets their first loss of the season 6-2 at Citi Field.

Met starter Dillon Gee allowed 8 of Washington's 13 hits in 5 2/3 innings while allowing three earned runs and striking out six.

Ian Desmond had two hits, including a solo-homer to lead-off the game.

Ross Detwiler (1-0) earned the win with five innings of two-hit ball. He K'd six.

New York was without star third baseman David Wright, who broke fractured a joint in his right pinkie while diving back into first base in Monday night's game. Team officials say he'll be re-evaluated on Wednesday and it's is unclear how much time Wright will miss.

Ronny Cedeno filled in for Wright, going 3 for 4 with an RBI. Justin Turner drove in New York's other run. The pair will likely fight for time in Wright's absence.

Manager Terry Collins also sat the struggling Ike Davis, who struck out in a pinch-hitting appearance Tuesday. He's 0 for 16 to start the season.

A Wednesday matinee (1:10) at Citi Field will feature Johan Santana for the Mets and Stephen Strasburg for the Nats.

Game Note: The two teams combined for 21 strikouts (New York 11 times, Washington 10). The Nats' Adam LaRoche, Xavier Nady and Roger Bernadina all K'd three times each.
