Boston ? Brian McNamee was planning to dump all his mementos of his relationship with Roger Clemens.

Then a friend persuaded him to think better of it.

Now the former personal trainer who claims he injected the seven-time Cy Young Award winner with steroids is selling dozens of personal items in an online auction, and donating the profits to his juvenile diabetes charity.

A baseball signed by Clemens and McNamee that started the day Wednesday at $38 was bidding $4,000 by late afternoon, said Phil Castinetti, a friend of McNamee’s and owner of SportsWorld in Saugus, Mass., who is handling the sale.
