Top seeds all through at Delray, rain halts play in Rio

Favourites Reilly Opelka and Grigor Dimitrov joined top seed Cameron Norrie in the quarter-finals of the Delray Beach Open after victories on Thursday.

With Norrie having already set up a quarter-final against last year’s runner-up Sebastian Korda, the Briton was joined in the last eight by the second and third seeds. 

Grigor Dimitrov defeated Mitchell Krueger to mark his first appearance since a disappointing second-round exit at the Australian Open in style.

The Bulgarian won 7-6 (7-4) 6-3, with Serena and Venus Williams watching on from the crowd in far from ideal conditions in Florida.

“It’s always very tough [in your opening match], especially playing the last match on,” Dimitrov said.

“I’ve been here for a week already and I was eager to get out there and play. Today was just a match I had to get through. Very tough conditions: rain, wind, cold, hot. It is what it is, and you’ve got to deal with it.”

Opelka, who won the tournament in 2020, went the distance against fellow American Jack Sock, eventually prevailing 6-7 (6-8) 7-6 (7-4) 6-1. 

He will face Adrian Mannarino in the last eight, after the Frenchman’s 6-4 2-6 7-5 defeat of Brandon Nakashima. Dimitrov will play Australian John Millman.

At the Rio Open, only two of the four scheduled matches were completed due to rain.

Qualifier Miomir Kecmanovic dispatched sixth seed Lorenzo Sonego 7-5 6-4, while Francisco Cerundolo overcame Roberto Carballes Baena.

Top seed Matteo Berrettini’s clash with Brazilian Thiago Monteiro was pushed back to Friday, while Carlos Alcaraz will resume his match against Federico Delbonis in a strong position in the first set.
