Finnegan gave up a hit and struck out one over 1.1 scoreless innings to record his fourth save of the season in Wednesday's 8-5 win over the Blue Jays.
The right-hander continues to thrive in a high-leverage role for the Nats. Finnegan has allowed only one earned run over his last 14 appearances and 14.1 innings, and he's converted four of five save chances since Brad Hand was dealt to Toronto just before the trade deadline.
