After watching this video, I now have a pretty good idea. The eccentric closer can don a kilt and get rid of some of his extra hot air by leading the rest of the Giants bullpen onto the field with a set of bagpipes — just like University of Oregon relief pitcher David Wylie does:
Ah, as Harry Caray used to say, you can't beat fun at the old ballpark, friends.
Make no mistake, either: That really is Wylie squawking his Duck teammates onto the field. The junior right-hander has "enjoys playing the bagpipes" listed in the personal section of his Oregon biography.
