I didn't see it, but the Veep threw out the first pitch at the Yankees-Orioles game and received thunderous booing.
I caught a bit of him in the ESPN broadcast booth and he stated he was a lifelong New York Yankees fan, his favorite player growing up was Mickey Mantle and now it's Derek Jeter.
I though that was odd for a kid from Scranton.
It is and the scientific community is united in that fact.
On two separate occasions (October 30 & November4) ABC has Biden's favorite baseball team being the Philadelphia Phillies.
An Obama/Biden blogger has him as a Phillies fan too.
Back in the booth, here's Biden's reaction to a nice play...
"That's a hell of a catch. Hell yea, hell yea!"
