The first round of the 2023 Australian Open gets underway on Sunday as top-ranked Iga Swiatek enters as the clear favorite, and for good reason. The 21-year-old from Poland is coming off a win at the 2022 U.S. Open, and was the French Open champion as well. But a rugged field won't make a second consecutive Grand Slam win a foregone conclusion. In fact, others that could vie for the title include Tunisian Ons Jabeur, ranked second in the world, as well as 11th-ranked Paula Badosa of Spain and Maria Sakkari of Greece, who is ranked sixth.

The latest 2023 Australian Open women's singles odds from Caesar's Sportsbook have Swiatek as the -110 betting favorite. Jabeur is at +1000, while Badosa and Sakkari are both at +1200. Others favored to win the Open include Coco Gauff at +1400, Carolina Garcia and Jessica Pegula at +1600 in the latest odds.
