Unseeded Mexican teenager Alfredo Avila celebrated a stunning success in the Rochester Pro-Am in the USA when he upset fourth-seeded Australian Wade Johnstone in the final of the PSA World Tour Challenger 5 squash event at the University of Rochester in Rochester.

The 19-year-old from Mexico City, ranked 115 in the world, made his breakthrough in the quarter-finals where he ousted top-seeded local hope Gilly Lane, the US No2 from Philadelphia, 6-11, 12-10, 11-5, 7-11, 11-8 in a 90-minute battle.

After then surviving a 101-minute marathon against fellow Mexican Erik Tepos Valtierra, the third seed, Avila reached the third Tour final of his career.

Johnstone, the world No107 from Perth, had also reached the final unexpectedly, after despatching England's No2 seed Eddie Charlton in a 90-minute five-game semi.

And it took more than an hour to settle the title, with Avila ultimately prevailing 6-11, 11-8, 11-6, 11-6 after 70 minutes to clinch the second Tour title of his career.
