Iga Swiatek dominated American Jessica Pegula 6-1 6-0 to win the season-ending WTA Finals in Cancun on Monday and regain her world number one ranking from Aryna Sabalenka.
The Polish player broke Pegula five times and won the final 11 games in a 59-minute slaughter to capture her first WTA Finals title in a match delayed by a day due to rain.
"I want to thank my team who have been with me for the whole season," Swiatek said during the trophy ceremony.
