The newlywed Keys, whose husband and coach is former American tennis player Bjorn Fratangelo, said after some much needed sleep, they'll be "back to work on Monday" to prepare for "lots of tournaments" including the BNP Paribas Open at Indian Wells and the Miami Open back to back in March.

Recent Australian Open champion Madison Keys sat down for an interview with CBS Morning, where she reflected on her emotions after winning her first Grand Slam title by defeating world No.

In total, Sinner has won 36 of his last 37 matches, his only defeat coming against Carlos Alcaraz in the final of October’s China Open.

The American tennis player, 29, secured her first grand slam title on Jan. 25, achieving a breakthrough win over world No. 1 Aryna Sabalenka, who was vying for what would have been a historic three-peat. The women's singles match at Melbourne's Rod Laver Arena saw Keys win 6-3, 2-6, 7-5.

The 29-year-old became the fourth-oldest first-time Grand Slam champion in the professional era, ending Sabalenka's bid for a third straight Melbourne Park crown.
