Lineups: Karns Debuts Against O's

With an 8.76 ERA in his last three starts at AA Harrisburg, Nate Karns will have a bit of a baptism by fire tonight against the #2 run-scoring team in baseball, the Baltimore Orioles. The Nats’ #5 prospect will have minor league company on the mound tonight, with the Orioles’ Kevin Gausman making his second major league start. In his first, he allowed four runs in five innings against the Blue Jays, but comes highly touted as the fourth overall pick of the 2012 MLB Draft. Here are the lineups for tonight’s game, featuring the ~~Harrisburg Senators and the Bowie Baysox~~ Washington Nationals and Baltimore Orioles.
