(March 23, 2026)From the USTA: Sixteen-year-old American Michael Antonius made history on Sunday by winning his first pro singles title at the USTA Pro Circuit M25-level tournament in Bakersfield, Calif. He beat 26-year-old American Andrew Fenty, 7-6(3), 6-2, to become the youngest player to win a men’s singles title on the global ITF World Tennis Tour since July 2014 and the youngest American to win a men’s singles title on the ITF circuit since records began in 1990.

Antonius, a Buffalo, N.Y., native, joins fellow American 16-year-old Andy Johnson in achieving a significant age-related benchmark with his first pro singles title. Last month, Johnson won his first pro title at an M15-level event in Sunrise, Fla., and became the youngest player since Carlos Alcaraz to win an ITF circuit singles title.

Seventeen-year-old Julieta Pareja also won her biggest ITF tour title to date last week at the W50-level event in Chihuahua, Mexico. Four American teenagers — Antonius, Johnson, Pareja and Akasha Urhobo (2) — have now won pro singles titles in 2026.
