World no. 74 Cameron Norrie is through to his first ATP semi-final since Atlanta 2019, beating the 8th seed and a former Delray Beach champion Frances Tiafoe 6-0, 3-6, 6-4. The encounter lasted for two hours and 13 minutes, and Cameron won eight points more than Frances, fending off nine out of 11 break chances and delivering five breaks from 17 opportunities.
The Briton was the only player on the court in the opener, serving well and producing three breaks for a bagel and the strongest start. Tiafoe squandered a 3-0 lead in set number two and fended off break opportunities at 3-3 to stay alive, rattling off the last three games to take the set 6-3 and extend his chances ahead of the decider.
The American had the momentum on his side and delivered four commanding holds to leave the pressure on the other side. Experiencing troubles in four different service games, Norrie fended off no less than nine break chances to remain 5-4 ahead, building confidence and stealing Tiafoe's serve in game ten to advance into the last four.
In the most anticipated clash of the day, the young gun Sebastian Korda took down world no. 25 John Isner 6-3, 4-6, 6-3 in an hour and 51 minutes for the first ATP semi-final. Korda lost 22 points in 14 service games and repelled five out of six break chances to challenge Isner to repeat those numbers if he wanted to stay in contention.
John won only 65% of the first serve points and suffered three breaks from seven opportunities offered to a teenager to end his run in the quarters. Sebastian survived two deuces in game four to avoid an early setback and converted the third break point at 3-3 following John's terrible volley at the net.
Sebastian Korda and Christian Harrison are in the first ATP semi-final.
The youngster grabbed another break at 5-3 when the veteran netted a forehand, playing well so far and gathering a boost ahead of set number two. Isner held at 30 four times in set number two and took the crucial points to avoid deuces or break chances.
Korda wasted a game point at 3-3 and sprayed a forehand error to lose serve for the first time, allowing Isner to win the set with a volley winner at 5-4. Nothing could separate them in the opening seven games of the decider, and that all changed when Korda placed a backhand winner at 4-3 that sent him in front.
Returning in game nine, Isner created three break chances that Korda repelled with brave hitting, earning a match point and seizing it with a service winner to advance into the semis. World no. 789 Christian Harrison still dreams in Delray Beach, beating Gianluca Mager 7-6, 6-4 to reach the first ATP semi-final.
The American saved three out of four break points and earned two breaks that carried him home and towards another impressive triumph, considering his ranking. Mager led 5-3 in the opener before Harrison pulled the break back in the last moment, reaching a tie break and winning it 7-2.
Christian scored a break in the second set's fifth game and sealed the deal with a hold at 15 in game ten. The 4th seed Hubert Hurkacz took down Roberto Quiroz 6-4, 6-4 in an hour and 25 minutes, stealing the rival's serve three times to remain on the title course.
