Nick Kyrgios says he feels ‘composed’ and ‘mature’ as he outlasted Brandon Nakashima to reach the Wimbledon quarter-finals.

It was a much more subdued performance by Kyrgios on Center Court compared to his incendiary match against Stefanos Tsitsipas on Saturday, and the Aussie admitted he was far from his best as he took the win 4-6 6-4 7-6 (7-2) 3-6 6-2.

It wasn’t until he scored a forehand on his first match point in the fifth set that Kyrgios showed real signs of emotion as he looked at the crowd and roared with delight.

The victory was also not easy, as the 27-year-old appeared to be struggling with a shoulder problem throughout the match and needed treatment from a physiotherapist at 3-2 in the third set.

“Tonight I definitely need a glass of wine,” he admitted in an interview on the court after the match.

Following Kyrgios is Chile’s Christian Garin, who became the first player at this year’s tournament to come back from two sets after defeating Australia’s Alex de Minor.

Kyrgios reached the quarter-finals of a Grand Slam tournament for the first time in seven years and remains undefeated in all five sets at Wimbledon.

“Today, I almost just smiled and laughed to myself on the opposite side, knowing that I was engaged in an absolute battle,” he told reporters. “Before, I couldn’t enjoy it… I almost enjoyed being competitive (today).”

American Nakashima, playing in his first match of the fourth round of the Grand Slam tournament, took the first set with the first break point of the match, but Kyrgios, despite grabbing his shoulder several times, hit back with a break early in the match. second.

The serve proved to be Kyrgios’ best weapon, with one ace hitting 137 mph as he completed the set and equalized.

There were few break opportunities for either player in the third set, but Kyrgios prevailed in the tie-break with a right hand out of Nakashima’s reach to advance the match.

Nakashima enjoyed his best Wimbledon performance this year as he lost in the first round last year.

However, the 20-year-old was far from over and took a 4-3 lead in the fourth round. This was followed by a strange passage of play in which Kyrgios seemed to play the rest of the set with slow serves and lackluster strikes on the ground.

“A complete rope and dope tactic,” he later explained. “I just threw that game on the pitch. I knew he was on the beat, he started to ride me and I just wanted to throw him off a bit.”

This meant that the match was decisive, but Kyrgios showed his best tennis, and Nakashima lost.

A double serve break set the stage for victory, and Kyrgios finished the match with 35 aces to bring his tournament tally to 103 and 79 winners.

He will now be in contention for his second Wimbledon quarter-final and first since 2014; then he famously defeated Rafael Nadal in the fourth round as a 19-year-old debutant.

His performance on Monday may not have had the infectious, pulsating energy of his victory over Nadal, but it was a daring win nonetheless.

“It was far from my best performance in terms of level, but I am very happy to get through it,” Kyrgios said. “Today I fought very hard.”

For the second time at Wimbledon this year, Kyrgios had to go five sets.

Controversy has typically accompanied Kyrgios throughout his tennis career, and this year’s Wimbledon was no exception.

He was fined $4,000 for verbal foul language in his match against Tsitsipasadding to the $10,000 he was fined for unsportsmanlike conduct after spitting at a fan he said was disrespectful to him during his first round match against Paul Jubb.

But Kyrgios admitted he is a different player and person than the one who met Nadal eight years ago, as evidenced by his calm demeanor on Monday.

Earlier this year, he revealed struggling with mental health issues with whom he dealt during his career, recounting his struggles with drug and alcohol abuse and self-harm.

On Monday, he could briefly reflect on what he called his “rollercoaster ride.”

“Look, there was a time when I was kicked out of the pub at 4am to play Nadal in the second round,” Kyrgios said.

“My agent had to come and pick me up from the pub at 4 am before I played my match on Wimbledon Center Court.

“I’ve come a long way, that’s for sure. I think it’s daily habits and the people around me… Now to sit here, the Wimbledon quarterfinals, feel good, feel collected, feel mature and have this around me, I’m very lucky and I feel comfortable in my own skin.”

Against Garin, a player three positions below him in the world rankings, but with less experience playing at the biggest sports stages, Kyrgios was able to reach the final four of a Grand Slam tournament for the first time.

This would be an important moment for a player used to the ups and downs of a professional tennis career.
