Game 17 lineups: Nats vs. Orioles

The first round of this year’s Battle of the Beltways begins tonight, and though the roles of the two participants have changed somewhat at this stage in each franchise’s development, there’s still reason to believe the baseball played the next two nights on South Capitol Street will be compelling.

The Nationals have been playing compelling baseball for nearly two weeks now: Nine of their last 10 games have been decided by one or two runs, the lone outlier a 10-5 win at Colorado. They’re also playing relatively low-scoring games, the average score this season checking in at 5.1-3.9 in the opponents’ favor. The Orioles have been playing a more varied brand of baseball so far. Nine of their 16 games have been decided by three or more runs, and their average score has been 5.9-5.4 in their favor.

Josiah Gray’s task tonight: Keep a potent lineup that ranks first in the American League in on-base percentage and second in slugging percentage and homers in check. He’s been pretty good at that so far, especially after his ragged opening inning to the season: He’s allowed only two homers in 15 innings since, while walking only five batters in 16 2/3 innings overall.

The Nats will have to try to hit the ball in the air against Dean Kremer, who has allowed five homers in only 12 1/3 innings to date, completing five innings only once in three starts. They got power from Jeimer Candelario and Luis García during Sunday’s win, so perhaps that will carry over into this week.
