Finnegan (4-5) took the loss Wednesday as the Nationals were downed 4-3 by the Marlins, recording one out and giving up an unearned run on one hit and two walks in the 10th inning.
The 29-year-old was essentially victim of the phantom runner rule in extra innings -- after Lewis Brinson laid down a sacrifice bunt to move Jesus Sanchez to third base to open the bottom of the 10th, Finnegan issued two intentional walks to load the bases only to give up a walkoff single to Jorge Alfaro. The right-hander has only allowed one earned run in nine August innings, picking up three saves on four chances plus a win and a hold, but he also has three losses on the month. Finnegan's 5:4 K:BB and five unearned runs are red flags that he's been more lucky than good as the Nats' closer.
