Here’s how much starting pitching depth the Nationals have: Bill Ladson of MLB.com reports that they’re likely to use Tanner Roark out of the bullpen in the playoffs and there’s really no strong reason to argue against it.
Roark was fantastic this season, posting a 2.85 ERA in 31 starts with a 138/39 K/BB ratio in 199 innings. And he was even better as a rookie last season, giving him a combined 2.57 ERA in 252 innings as a big leaguer.
For a lot of teams that’s a No. 1 or No. 2 starter in the playoffs, but the Nationals have Stephen Strasburg, Jordan Zimmermann, Doug Fister, and Gio Gonzalez.
