Game 158 lineups: Nats at Rockies

By any measure, it's been a miserable season for Patrick Corbin. The left-hander enters tonight's start at Coors Field with a 9-15 record and 5.92 ERA. A bad outing in this one, and he might just complete one of the worst seasons by any big league starter in a long time. The last pitcher to lose 16 games while posting an ERA over 6.00: Jason Marquis of the 2006 Cardinals (a team that actually won the World Series).

So, Corbin would certainly like to avoid reaching both of those thresholds tonight in what could be his final outing of the year. Davey Martinez said Monday he hasn't decided yet how his rotation will line up for the weekend against the Red Sox, but he hinted he may try to ensure both Josiah Gray (who pitched Monday) and Corbin get a start. So perhaps there's still one more attempt for the lefty on Sunday in Game 162.

Starts could also be running out for Ryan Zimmerman, who has not yet decided if he plans to return next season (at least not publicly). Today is Zimmerman's 37th birthday, and he's in the lineup against Rockies lefty Kyle Freeland. It's entirely possible this is one of the last games he'll ever start in his career.
