Coco Gauff's dreams of a first Australian Open title were snuffed out in the quarterfinals by Paula Badosa before Novak Djokovic and Carlos Alcaraz face off in a duel for the ages on Tuesday.

Paula Badosa stunned Coco Gauff to reach her first Grand Slam semi-final and Alexander Zverev overcame Tommy Paul to book his ninth as the Australian Open awaited the blockbuster Tuesday evening clash between Novak Djokovic and Carlos Alcaraz.

MELBOURNE, Australia — Coco Gauff's retooled forehand and serve abandoned her in the worst way and at the worst time at the Australian Open. The unforced errors just kept accumulating, and so did the double-faults and break points, often followed by a palm placed over her eyes or a slap to a thigh.

Coco Gauff’s quest for a return trip to the semifinals in Melbourne has come to an end. Spain’s Paula Badosa stunned Gauff and grabbed a 7-5, 6-4 win in straight sets in what was a hot battle at Rod Laver Arena on Tuesday afternoon to earn her spot in the semifinals of the first Grand Slam of the year.
