Jordan Zimmermann may have earned the distinction as the Nats pitcher who never gets any run support, but Edwin Jackson has had it worse of late.
Jackson has allowed a total of five earned runs over the course of his last three starts and the Nationals have lost each of those games. In each game the Nats mustered just one run and that run wasnt scored until at least the sixth inning in all three outings.
Jackson has one win on the season despite a 3.17 ERA and 1.026 WHIP through 65.1 innings this season. The Nationals have lost each of his last five starts despite Jackson allowing three runs or fewer in each of them. The only times Washington has won with Jackson pitching were when he threw a two-hit complete game on April 14 vs. the Reds and on May 2 when Ian Desmond hit a walk-off home run against Arizona.
Jackson this year is actually pitching his best on the road, he holds a 2.89 ERA through 37.1 innings in away games but is 0-and-2 in those starts. He has earned the losses in consecutive games, his two most recent appearances. On May 23 he allowed three earned runs at Philadelphia and on May 29 took the loss despite just one earned run at Miami.
It is still early in the year, the Nationals have played just 49 games, but through his first ten starts Jackson is putting together one of his strongest seasons. His 3.17 ERA would be the lowest of his career if he keeps it up. If he continues his pace the wins should start piling up at some point, but if not he may need to start hitting home runs like Zimmermann and Stephen Strasburg.
