Iga Swiatek dominated American Jessica Pegula 6-1 6-0 to win the season-ending WTA Finals in Cancun and regain her world number one ranking from Aryna Sabalenka.
The Polish four-time Grand Slam winner broke Pegula five times and saved the only break point she faced en route to her first WTA Finals trophy in a match delayed a day due to rain.
The 22-year-old was in clinical mood as Pegula struggled to find her range in a match lasting just 59 minutes.
It is the first time Swiatek has won the WTA Finals tournament.
The final took place a day late on Monday following bad weather at the event but was played out in sunshine at the venue in Mexico.
Swiatek was quickly out of the blocks and broke in the fourth game to take a 3-1 lead before racing away to claim the first set in 27 minutes.
It was the first set either player had dropped at the event and Pegula, the world number five, lost her serve for a third time in the first game of the second set.
Swiatek was overwhelming her rival and broke to love to go 3-0 up on the way to securing victory.
