Venus Williams' return to the US Open was short-lived, but not before she put up a valiant effort in a 6-3, 2-6, 6-1 loss to No. 11 Karolina Muchova in the first round on Monday night.

Venus Williams, 45, played her first Grand Slam match in two years at the US Open on Monday, displaying some big serves and powerful groundstrokes before losing 6-3, 2-6, 6-1 to Karolina Muchova.

The 45-year-old brought her big serve and powerful groundstrokes to the fore before falling to 11th seed Karolina Muchova.

On the court, Alcaraz seemed unfazed by the added attention from his haircut. He needed just over two hours to see off the towering, big-serving Opelka in Arthur Ashe Stadium and kick off his pursuit of a sixth grand slam title and second at the US Open.

Carlos Alcaraz showed up at the U.S. Open on Monday for his first-round match with a new look: a shaved head. Alcaraz, who is seeded No. 2 at Flushing Meadows, caused a bit of a buzz with his buzz cut when he got to the tournament grounds before facing Reilly Opelka in Arthur Ashe Stadium.

Carlos Alcaraz 's haircut rather than his tennis was the talk of the US Open as the second seed eased into round two in New York. The Spaniard arrived at Flushing Meadows on Monday ahead of his clash with Reilly Opelka looking almost unrecognisable after shaving his head.
