NEW YORK -- The New York Mets have now lost three straight series since their 11-game winning streak.
Washington (12-14) has won 17 of its last 19 games in Queens spanning three seasons, including three of four during the current visit.
An inning later, Matt Thornton walked a pair of batters and issued a wild pitch. With two in scoring position and one out, Thornton struck out Lucas Duda. Aaron Barrett then entered and struck out Michael Cuddyer, too.
The Mets lost consecutive 1-0 games for the first time since Sept. 4-5, 1990, at St. Louis and Pittsburgh.
A single opponent had not produced consecutive 1-0 wins in a series against the Mets since the Chicago Cubs on April 17-18, 1973, at Shea Stadium.
After Gee issued a game-opening walk to Denard Span, Yunel Escobar sent a would-be double-play grounder to second base. Tejada -- starting at shortstop for a second straight day over Flores -- accepted the throw from Herrera and recorded the forceout at second base. However, Tejada double-clutched on the throw to first base and Escobar beat out the play. Escobar was forced out on an ensuing fielder's choice grounder by Jayson Werth. However, Werth ended up scoring on a two-out single by Ryan Zimmerman that dropped into shallow right field.
Gee did get help at points, too.
Cuddyer jumped at the left-field wall and took away a potential solo homer from Zimmerman in the fourth.
In the sixth, Alex Torres inherited the bases loaded and none out from Gee. Torres proceeded to strike out three straight batters to hold the Mets' deficit at 1-0.
Gee was charged with one run on six hits and five walks (one intentional) in five-plus innings.
Taking the fifth: Gee completed five innings for the 51st straight game, the longest active streak in the majors. It established a franchise record, surpassing 50 straight by Dwight Gooden from 1987 through '89.
What's next: The Mets take a day off Monday before welcoming the Baltimore Orioles to Citi Field for two games. Bartolo Colon (4-1, 3.31 ERA) opposes right-hander Bud Norris (1-2, 12.18) in Tuesday's 7:10 p.m. ET series opener.
