No word on what anyone's nickname is, but Rob Bradford says bullpen coach Gary Tuck told him that "the relievers call the Fenway bullpen 'The Black Pearl' and have secret handshakes upon entering The Pearl".
Also from the Bradford Files:
Speaking of Gagne, I got the chance to ask him about that game at Fenway Park in which he came in for an injured Akinori Otsuka. The reliever was showered with boos when he wouldn't leave the bullpen to take his warmup pitches. Here is the explanation:
"I knew you could warm up on the field, but I didn't know you had to," Gagne said. "My pitching coach was like, 'You've got to go out there.' I'm like, 'I don't want to, I want to warm up here.' He told me I had to get out there because it was the rule."
