Top seed Beiwen Zhang of the United States overcame Canadian teenager Rachel Chan to secure her first women's singles title at the Pan American Individual Badminton Championships in Guatemala.
Zhang produced a controlled display to beat Chan, playing in her first event at this level, 21-14, 21-18 in the final in Guatemala City.
The result gave the 30-year-old American player one of the biggest triumphs of her career.
Brian Yang of Canada was crowned as the men's champion after compatriot and top seed Jason Anthony Ho-Shue retired hurt when trailing 21-13, 18-10.
Ho-Shue was also unable to team up with Nyl Yakura in the men's doubles final as a result of the injury, handing the title to Phillip Chew and Ryan Chew of the US.
Canada's Rachel Honderich and Kristen Tsai sealed the women's doubles crown by sweeping aside Americans Francesca Corbett and Allison Lee 21-12 21-7.
The mixed doubles honours were clinched by Joshua Hurlburt-Yu and Josephine Wu, who defended their title with a 21-18 21-18 victory over Guatemala's Christopher Alexander Martinez Salvador and Mariana Isabel Paiz Quan.
