Alvin "Fats" Roth (November 2, 1929 – June 19, 2003) was an American professional basketball player known for his playing days at the City College of New York (CCNY) between 1949–50 and 1950–51. Roth was a contributing member of the only basketball team in NCAA history to win both the National Invitation Tournament (NIT) and NCAA Tournament in the same season.^[1] Roth was one of four sophomore starters on the CCNY squad that defeated Bradley in both championship games.^[2][3]

Roth was 6'4", weighed 210 pounds and played guard.^[1] He grew up in Brooklyn, New York, and attended Erasmus Hall High School, where as a senior in 1947–48 he led them to a PSAL championship.^[1][3] Due to his poor academic grades, Roth was ineligible to attend CCNY his freshman year;^[3] one year later Roth was admitted to the school as a sophomore.^[3] It was this season that CCNY won both national basketball championships (the NIT was actually considered the premier national championship at the time). One year later, news broke about a point-shaving scandal that was sweeping east coast universities, and at its heart was CCNY's squad led by Nat Holman.^[1][3] Roth was one of the players arrested in the scandal.^[1] In July 1952, a judge suspended his sentence after Roth volunteered to join the United States Army as a private in the following month.^[4]

Roth's admission into CCNY despite his poor grades was a result of transcript altering by Holman.^[3] Nationally, all of the players who were convicted of participating in the scandal were banned from ever playing in the National Basketball Association (NBA).^[1]

Due to his ban, Roth played for a time in the Eastern League, although it is unknown which team he played for.^[1]

After his playing days, Roth went back to CCNY to earn his business degree, then moved to the suburbs of New York City to sell insurance.^[1] He died June 19, 2003, in Rockford, New York.^[5]
