Back when Don Amorosi, aka “Gobo,” started a most clean frames pot for the USBC Open Championships in 2009 in Las Vegas, he called it the "Riggs 90 Clean Pot" in honor of me going 90 frames clean in the 1997 tournament in Hunstville, Alabama, and my activity on the then-USBC message boards.

I obviously was honored, although I should note again that the achievement carried no pressure as I did not even know I did it until I was looking at my scoresheets after I was done.

Then in 2011, USBC found that at least two other players had gone 90 clean, and perhaps more since full scoresheets aren’t available for most of the tournament’s history, as I detailed here. 

Gobo didn’t end the Riggs 90 Clean as those who entered wanted him to keep doing it. I had no problem with that so long as people realize that my achievement was not unique. 

USBC copied Amorosi and ran a 90 Clean pot for a year but then abandoned it, and USBC has no involvement with Amorosi's 90 Clean.  

Gobo has continued running it most years and again will offer it in Las Vegas this year.

The entry fee is $15 for both the regular and senior divisions. A senior player can enter both divisions.

To enter, you can pay by check payable to "Riggs 90 Clean," or via Paypal to [email protected], or through Rick Ramsey at the BTM Tournament. Gobo’s mailing address is PO Box 651, Piscataway, NJ 08855.

A person is considered a senior if they turn 50 at any time during the course of the tournament, even if they bowl before they turn 50.

The payout ratio is 1 in 7 for both divisions.

Recap sheets must be mailed to Gobo or faxed to him at 732-302-9729.

For details, e-mail Amorosi at [email protected] or call him at 732-489-0947 or 732-469-0668.
