Previously, racquetball games used side-out scoring, where players scored points only when they had won a rally which began with that player serving.
Mexicans Álvaro Beltrán and Daniel de la Rosa won the division for the second time together; the first was in 2018.
It's Beltran's 5th Men's Doubles World Championship, winning the others with Javier Moreno.
The Mexicans defeated Bolivians Roland Keller and Conrrado Moscoso in the final, 7–11, 12–14, 11–7, 11–5, 11–6.
Initially, players competed in separate groups over three days.
