World number one Iga Swiatek claimed her eighth WTA Tour title of the season, storming home to claim a three-set victory over Donna Vekic in the San Diego Open final on Sunday.
Swiatek improved her record in the United States to 24-1 this season with the victory in one hour and 47 minutes, getting past the Croatian qualifier 6-3 3-6 6-0.
The Pole previously won the US Open, along with the Indian Wells and Miami titles this season.
Top seed Swiatek secured her 64th win of the season, which is the most since Serena Williams won 78 in 2013.
Vekic ensured it was not easy for Swiatek, continuing her excellent week – knocking out Maria Sakkari, Karolina Pliskova, Aryna Sabalenka and Danielle Collins – with a strong second set.
The Croatian actually had to complete her semi-final earlier on Sunday after a rain-interrupted encounter with Collins, winning 6-4 4-6 7-6 (7-2) after resuming 4-2 down in the third set, before taking on Swiatek.
Swiatek’s dominance was felt, winning 82 per cent of her second-serve points, ruthlessly converting four of six break points as well.
Vekic only generated one break point for the match but she took it, keeping the match alive in the second set where she was more aggressive.
The 2022 US Open and French Open champion responded emphatically in the final frame, capitalising on three of four break points and winning 24 of the 29 points for the set to triumph.
