PHOENIX -- Kirk Gibson has caught Bieber Fever.
OK, that might be a bit of a stretch, as it's doubtful the D-backs manager has even heard one of Justin Bieber's songs, but Gibson is joining his player's efforts to raise money for charity.
D-backs closer J.J. Putz discovered a signed Bieber trading card in a pack he opened last weekend, and he agreed to auction the card off to benefit the charities of fellow relievers Craig Breslow and Brad Ziegler.
The D-backs' organization has agreed to donate a matching amount up to $2,500, as have Putz, Ziegler and Breslow.
Gibson told the players Friday that he too would match up to $2,500.
"Just to support my guys," Gibson said. "I certainly want to give back, No. 1. I think it's awesome, the life that [the card auction] has taken on, and it's important to those guys and they're very dedicated with their charities. The least I can do is be on board with those guys, support them in their causes."
As of the start of Friday night's game, the leading bid was just over $2,500.
