Bad Baseball, But A Couple Good Phillies Signs During Astros Series

The Astros are so bad that their Saturday game was not even televised in Houston.  The Phillies did televise their game, but there were a couple signs from fans more interesting than the games themselves.

First, we have this brave kid, who comes courtesy of Buzz Feed:

Sign this kid to a contract.  He appears to have the most fight in the ballpark.

Second, the Phillies refuse to "loose".  Do they mean "play loose?"   Do they mean that they refuse to "loose" as in "let go" of the season?

I'm confused.  My guess is that the picture belongs on www.grammardisasters.com.

Finally, this is not a sign, other than it being a sign they can't sell tickets.  If the Phillies ever have a "bring your dog to the ballpark" day, I quit watching baseball.

Who cleaned up after these dogs?
