Host nation Mexico finished the International Mixed Martial Arts Federation (IMMAF) Pan American Championships on top of the medals table with six golds.

Brenda Castro and Wendy Widrobo Espinoza of Mexico began proceedings on the final day in Monterrey in the women's under-47.6-kilograms division.

It was Castro who had the edge, submitting Espinoza in the second round after taking her back and locking her in a rear-naked choke.

Jaime Sierra and Aaron Rios both stood out for Mexico as each of them won via submission in their respective divisions, the men's under 56.7kg and men's under-93kg.

In the women's under-56.7kg class Isabel Sierra Martinez picked up a points victory against Colombian Laura Beltran Oquendo to secure gold before Samantha Teutle won Mexico's sixth gold in the women's under-70.3kg division over Shenese Bobb of Guyana.

Adrian Ledezma began the United States’ haul of medals in the seventh bout of the day.

He submitted Mexico’s Diego Alexis Torres with a modified guillotine in the opening round of the men's under-52.2kg decider.

The US ended the day with five gold medals following dominant displays from Jonathan Powell, Anthony Orozco, Shane Collins and Lester Batres Jr in the men's under-65.8kg, under-83.9kg, under-70.3kg, and under-77.1kg divisions, respectively.

Brazil made it a hat-trick of wins in the women’s divisions as Giulliany Perea, Josiane Oliveira and Ana Vitoria Diniz all comfortably won their bouts.

In the under-61.2kg category, Oliveira was forced to go the distance in her bout, while both Perea and Diniz utilised their slick submission skills to win via kneebar in the under-52.2kg and under-65.8kg.

Caio Sardella rounded off a successful day for Brazil by submitting Puerto Rico’s Anthony Ramirez in the men's under-300kg division with a guillotine choke during the final seconds of the round.

Trinidad and Tobago earned their sole gold medal of the competition in the men's under-120.2kg tournament through Jeremy Rodulfo as two victories in as many days saw him earn the heavyweight gold medal.
