Harper, the National League Rookie of the Year, will appear tonight on ABC's "Jimmy Kimmel Live," which emanates from the City of Angels. The show starts at 11:35 p.m. Eastern time.
Memo to show host Jimmy Kimmel: Watch the clown questions, bro.
This is a nice get for the Nats, who have an opportunity to enhance their national profile through this appearance. Harper, however, isn't the first Nats player with a late-night appearance on his resume - you'll remember that Stephen Strasburg had "Top 10 List" duties on David Letterman's CBS gabfest after his debut in June 2010.
It's also a nice consolation prize for Harper, who didn't win the social media vote to appear on the cover of MLB 13 The Show. That honor went to the Pirates' Andrew McCutchen.
