From ESPN.com’s Darrell Rovell.

A Nike spokesman confirmed to ESPN.com on Thursday that the shoe and apparel company “no longer has a relationship” with the New York Yankees slugger.

It is not known whether the company’s decision not to renew Giambi’s contract is related to his reported admission of steroid use or is a result of his poor performance on the field.

Or, his current status as a national laughing stock, or d) all of the above.
