Hoist your flag

Right before running out onto the floor for any game, I turn to my partners and say the following:

"Whistle check!" (We pat our chests to confirm we haven't forgotten our whistles.)
"Fly check!" (We double-check our zippers.)

Well, in this area, I'm clearly more effective than a major league baseball umpire:

Home-plate umpire Kerwin Danley spent a good part of Tuesday's game with his pants zipper down and clearly visible to television viewers. A message was relayed to an umpire attendant, who sprinted out to Danley after the top of the fifth inning to warn him of his "wardrobe malfunction."

A laughing Danley quickly zipped up.

The missing information: who relayed the message to the umpire attendant? It was nice of that someone to let Danley know. It's also nice that Danley took it with humor.
