Are things starting to close in on you, Barry?

Thursday was NOT a good day for Barry Bonds, facing an upcoming perjury trial in March.

First, a source claims prosecutors have urine samples they say proved Bonds used steroids other than those known as “the cream” and “the clear” — the ones Bonds reportedly indicated he thought were “flaxseed oil.”

Then it’s learned that former San Francisco teammate and known juice Bobby Estalella is expected to testify and provide significant information that Bonds knowingly took the illegal substances.

Bonds, especially after he bulked up and slowed down, hit into a few double plays in his time, but this one — if completed — won’t send him to the dugout but to the slammer.
