The pressure was greater on the Braves to win the game than the Nationals and with Medlen's stuff with the pressure of a 0-0 game building. it would have only taken a little less control on a few pitches to give the Nationals the lead. Again, assuming we get a clean game from the Nationals.
That's true, but I'd argue that Det cracked under similar pressure to keep it at 0-0 when he walked Medlen and then also to keep it at 2-0 when he eventually was pulled in the 6th (though Stammen was able to wiggle out of it).
