Game 129 lineups: Nats at Mets

NEW YORK - Gio Gonzalez's season has, by every measure, been a colossal disappointment. If you want to compile a list of things that went wrong this year, the lefty's performance ranks high. One positive constant remains for Gonzalez, though: He still dominates the Mets.

Gonzalez enters tonight's start at Citi Field the owner of a 15-5 record and 2.90 ERA in 25 career starts versus New York. And that includes a 1-0 record and 2.53 ERA in his two head-to-head matchups this season. Both of those starts were back in April, and obviously he's a very different pitcher now than he was then. But if there was ever a reason to believe things could turn around for Gonzalez, tonight's matchup would be the place to start.

Speaking of disappointing lefties, Jason Vargas has been an unmitigated disaster for the Mets. Signed to a two-year, $16 million deal prior to the season, he has gone 3-8 with a 7.67 ERA in 14 starts, missing two different sizeable chunks of time with different injuries. Because of that, the Nationals actually haven't seen Vargas yet this year. Only four members of the current roster have ever seen him: Matt Wieters (5-for-19), Mark Reynolds (3-for-8), Adam Eaton (1-for-5) and Ryan Zimmerman (2-for-5).
