Nick Kyrgios’ comeback trail cut short after grim 21-minute implosion.

Karen Khachanov ensured the Nick Kyrgios comeback trail was cut short, with the Russian star clinching a 7-6 (7/3), 6-0 straight sets win at the Miami Open on Friday.

Australian Kyrgios, who has struggled with a wrist surgery, defeated Mackenzie McDonald in the first round to earn his first tour-level win since October 2022 — but he was unable to overcome Khachanov, who reached the semis in Miami in 2023.

After bottling a chance to go 3-1 up in the first-set tiebreak, Kyrgios became frustrated with his team at courtside, with his game falling apart from there on. The 29-year-old delivered a dismal second-set performance, mustering just seven points in a set that lasted just 21 minutes.

Meanwhile, Kyrgios received a warning from the chair umpire for smashing a ball high out of court.

Elsewhere in the Miami Open, Daniil Medvedev crashed out in the second round after suffering a 6-2, 6-3 upset defeat to Spain’s 56th-ranked Jaume Munar.

Medvedev, the 2023 winner in Miami, showed his frustration, hurling his racket on several occasions as the Mallorca-born 27-year-old picked up his third career win against a top 10 opponent.

The Russian made 32 unforced errors and although he gave himself a chance of a comeback in the final game, he couldn’t convert on two break points.

In the women’s draw, world number two Iga Swiatek advanced into the third round after surviving a second set dip to beat France’s Caroline Garcia 6-2, 7-5.

Swiatek had beaten Garcia with ease at the same stage at Indian Wells earlier this month but she faced a little more resistance at Hard Rock Stadium.

Swiatek was 3-1 down in the second set and had to save a set point, when serving at 5-4 down before rallying to win the last three games.

“My energy level got down really fast. So I tried to wake myself up, keep the intensity from the first set, follow through and go for it,” Swiatek said.

Swiatek lost to Mirra Andreeva in the semi-finals at Indian Wells, with the 17-year-old Russian going on to win the title.
