Australia's Olivia Gadecki has continued her strong run of form at the WTA 500 event in Mexico with a straight-sets upset of world No.11 Danielle Collins.
The 22-year-old qualifier dismissed the second-seeded American 6-3 6-3 at the Guadalajara Open and now has a 2-1 career record against top-20 players.
Her previous win over an opponent of that standing came against then-world No.4 Sofia Kenin back in 2021.
Gadecki, ranked 152 in the world, converted four of her nine break points and won 68 per cent of second-serve return points against Collins during her 84-minute victory.

Collins made 35 unforced errors, including eight double faults, and has now lost three straight matches since her injury retirement in her Paris Olympics quarter-final against world No.1 Iga Swiatek.
Gadecki, who beat America's Sloane Stephens in the opening round, advances to the quarter-finals, where she will meet either Mexico's Renata Zarazua (ranked 85) or Italy's Martina Trevisan (99).
It continues a good run for Gadecki this year, after she secured doubles titles in Austin and Charleston with Brit Olivia Nicholls.
