Defending champion Arena Sabalenka crashed from the Cincinnati Open after a 6-1, 6-4 loss to Elena Rivakina in the quarter-finals.
Rivakina appears to be violating the dominant opening set, and she dropped a lonely game and rounded out an impressive victory in just 1 hour and 14 minutes, offering 11 aces.
The victory returns to Rivakina form, following the semi-finals at Toronto’s National Bank Open.

Carlos Alcaraz saw the lively Andrei Rublev to book his spot in the semi-finals of the competition with a 6-3, 4-6, 7-5 victory.
Alkaraz scored the first set, but Rublev accidentally fought back in the second set, making it seem that Alkaraz sealed the victory when he broke Rublev to go 5-3, but his opponent went straight back and brought the contest back to serve.
Rublev had to hold service to take the game to a tiebreak, but Alcaraz’s fatal double fault won.
The 22-year-old hits 11 aces on his way to victory, facing either Ben Shelton or Alexander Zverev.
