Treinen gave up a run on two hits while striking out two in the ninth inning Wednesday, recording his second save of the season in a 6-4 win over the Marlins.
Neither ball was particularly hard hit, as Dee Gordon smacked a grounder up the middle for a single and was offered no resistance when he stole second, only for J.T. Realmuto to squib a ball into shallow right field with two outs to bring Gordon home. Treinen then buckled down and struck out Christian Yelich on four pitches to end the game. The right-hander has looked impressive through the early going as the Nats' closer, and his confidence should be growing with each successful save.
