“In my opinion, one of the reasons why it’s going to be so hard for Carlos to get close to Novak and Roger in Grand Slams is that there are bigger players out there like Shelton who can come out and play unbelievable matches and sort of take the racquet out of Carlos’ hands and frustrate him,” John McEnroe stated in the podcast Off Court.
Carlos Alcaraz faces a difficult path if he hopes to match the career Grand Slam totals of Roger Federer and Novak Djokovic, according to American tennis legend John McEnroe. Speaking during an appearance on the Off Court podcast ahead of Alcaraz’s appearance in the ATP Tokyo final against Jiri Lehecka, the seven-time major champion dissected the physical and tactical challenges confronting the Spanish star on the professional tour.
How Tall Opponents and Heavy Servers Threaten Alcaraz’s Grand Slam Ambitions
Alcaraz returned to the tennis circuit following a four-and-a-half-month layoff due to a wrist injury, working his way back to competitive form at the US Open and the Laver Cup. While the 23-year-old Spaniard captured his first title since February at the ATP Tokyo tournament and already boasts seven Grand Slam titles alongside an Olympic silver medal, McEnroe argued that the evolving competition in men's tennis will test Alcaraz's limits.

Unlike previous eras where tall servers like John Isner or Sam Querrey relied primarily on their serves, modern towering opponents are increasingly capable of sustaining grueling baseline rallies and dictating the pace of play. McEnroe highlighted Ben Shelton as a prime example of this evolution. During the US Open, Shelton relied on his imposing size and home-crowd energy in New York to dismantle Alcaraz’s rhythm and seize the initiative during what McEnroe described as the American’s best match of his life.
“If you watch him play, Alcaraz didn’t look rusty, but that lack of match sharpness came out against a bigger player who played the best match of his life, and who fed off the energy in the atmosphere and the home crowd support,” McEnroe said on the podcast.
Why the US Open Defeat to Ben Shelton Highlights a Broader Tactical Challenge
Despite the exit at Flushing Meadows where Shelton ultimately halted Alcaraz’s progression in the tournament, McEnroe maintained that the overall verdict on the Spaniard’s comeback remains overwhelmingly positive. The analysis noted that as the American major progressed, observers expected Alcaraz to claim the title despite lacking ideal match conditioning and dealing with physical fatigue.
The defeat also revealed the unique manner in which Alcaraz handles high-stakes losses. Media reports highlighted how Alcaraz left the court following his defeat to Shelton with a wide smile, a gesture McEnroe acknowledged by saying, “It looked like Alcaraz left the court at the US Open with a smile on his face, and I hope he doesn’t feel the after-effects of the loss and that he can move forward.”

The Next Challenge on the ATP Tour Following the Return from Injury
Alcaraz’s successful recovery from his lengthy wrist injury has proven that his competitive fire remains intact, even as tennis analysts debate his long-term trajectory against the all-time records held by Federer and Djokovic. Following his successful campaign to help Team Europe capture the Laver Cup and his run to the Tokyo final against Jiri Lehecka, the world’s elite continue to monitor how the young champion adapts to the physical demands of an unforgiving global schedule.
