This tickled me in the right way :
" Here's a question: When there's a fight on the field and both the benches and the bullpens empty, are the pitchers allowed to ride into the fray on those bullpen carts? Because if they were all on the one cart, hanging off the sides like in Road Warrior, waving bats, that would be cool. Not so cool: If the cart was shaped like a large baseball, and driven by the team mascot. These are the things that come to mind while watching the Phillies and Marlins fight on Thursday ... one has to make it interesting somehow. It was in the fourth inning when Florida starter Dontrelle Willis began shouting into Philadelphia's dugout, angry that Jon Lieber had been, he believed, throwing at him. The benches cleared, shoving ensued, and someone even threw a punch (no!). The game then went past midnight before Miguel Cabrera doubled off the scoreboard in the 11th to drive in the winning run in the Marlins' 5-4 victory. The Phillies left 17 on base, which is always fun."
Thanks Deadspin Boys
Or you know, they can just ride piggyback to the fight.
