You can love Bryce Harper all you want, but there’s a limit to how far you can go in telling him that when you watch him play.

A friend of DCist tweeted yesterday that a fan was thrown out of the game against the Atlanta Braves for holding up a sign that said, “I’m in love with Harper’s long balls.” Clever? Sure. Appropriate? Well, that’s debatable. Enough to get someone booted? Yep.

According to the team’s policies on what’s allowed on signs in the stadium, it really is up to the eye of the beholder as to whether something crosses the line or not. The policies stress that despite being owned by the D.C. taxpayers, the stadium “is not a forum or place for use by the public at large for assembly and speech, for use by certain speakers or for the discussion of certain subjects.”

And though the sign did contain content pertaining to baseball and a team player—all of which is permitted—it probably violated the prohibition on signs bearing messages that are “obscene, vulgar or indecent and inappropriate for viewing by children.”

So what could the Harper uber fan have done to more appropriately shown their love for the baseball phenom? Follow the lead of this fan, who in June held up a “Bryce, call me maybe?” sign during a game.

Or maybe just feel good that Nats Park isn’t FedEx Field, where no signs are permitted.
