RIYADH (Reuters) -World number two Iga Swiatek began her quest for a second WTA Finals trophy with a 6-1 6-2 win over Australian Open champion Madison Keys in their round robin clash at the season-ending championships on Saturday.

The 2023 champion made a fast start in the Riyadh showpiece, winning 12 of the first 14 points to take a 3-0 lead as a rusty Keys struggled to find rhythm on serve in her first match since a stunning U.S. Open first-round defeat in late August.
