In the second half of the season, Edwin Jackson has the third-best ERA (3.18) of Nationals starters behind Ross Detwiler and Stephen Strasburg. Two of his past three starts, including his last one, has been electric: an 11-strikeout performance against the New York Mets and 10-strikeout, eight-inning masterpiece against the St. Louis Cardinals last week. The right-hander (8-9, 3.53 ERA) is averaging seven strikeouts per outing since the all-star break. He is opposed by left-hander Chris Rusin (0-1, 1.80 ERA). As always, talk about the game here.
