Treinen allowed one hit and struck out three in 1.2 innings during Saturday's loss to the Reds.
That's now nine straight scoreless appearances for Treinen, who has a strong 2.70 ERA, 1.24 WHIP and 25:10 K:BB in 23.1 innings this season. He doesn't get used in particularly high-leverage situations, however, and with no saves and only five holds, his fantasy value is somewhat limited. If injuries or trades were to shake up the Nats' bullpen, Treinen might end up being the biggest beneficiary.
