Former Celtic Has No Pot of Gold to Pee In

Vin Baker may wanna lace his Reebok Pumps back up -- because the former basketballer ain't ballin' any more!

Baker's nearly 10,000 sq. ft. Conn. home is going up on the auction blocks later this month for a decent $2.3 million, according to ml-implode.com.

This isn't Vin's first dance with foreclosure -- his restaurant, Vinnie's Saybrook Fish House, also went under earlier this year.
