Norrie and Boulter knocked out of Miami Open

Cameron Norrie and Katie Boulter were both knocked out in the third round of the Miami Open, ending British hopes in the singles in Florida.

Norrie, 30, suffered a 7-5 6-7 (4-7) 6-4 defeat by 21-year-old Alex Michelsen of the United States in his first match of the tournament.

The 23rd seed, who replaced Jack Draper as British number one last week, lost a tight first set after Michelsen finally broke his serve with his sixth set point of the 12th game.

Norrie bounced back from a 3-0 deficit in the second set to force a tie-break which he won to force a deciding set.

However, a break in the third game of the third set proved pivotal for Michelsen as he served his way into the last 16 on home soil.

Muchova broke 29-year-old Boulter’s serve twice in the first set and only needed one more in the second set to go 6-5 ahead before she wrapped up the victory.

Elsewhere, British number four Fran Jones also exited the tournament, retiring in the second set of her match with American Jessica Pegula through illness.

Jones, 25, had knocked out Venus Williams in the first round despite feeling under the weather but struggled against Pegula.

Pegula had won the first set 6-1 and despite a medical timeout Jones, who was seen coughing several times during the match, decided at 3-0 down in the second set she was not well enough to continue.

“I didn’t want to lose the opportunity to play Venus, but it’s a whole different ball game playing Jess,” Jones said.
