The Miami Open has seen a series of surprises—is Sinner's Sunshine Double secure?

The Miami Masters has determined the men's singles quarterfinalists. Unlike the previously held Indian Wells Masters, where the list of players advancing to deeper rounds was exceptionally stable, this tournament, often called the "Fifth Grand Slam," has been full of unexpected outcomes. Although only a few non-seeded players remain among the quarterfinalists, many top players have already been eliminated early.

The first to fall was the youngest champion in the tournament's history, Alcaraz. Four years ago, he defeated Ruud in the final to win his first Masters title. Over the past four years, his achievements in major tournaments are well-known and need no elaboration, but his recent performances at the Miami Masters have been less satisfactory.

Last year, he lost here to Goffin, the Belgian top player ranked outside the top 50; this year, he fell to Korda. Although the American is ranked near the top 30 and is considered a formidable contender among the second-tier of the next generation, his career has been intermittent, and his consistency cannot be compared to compatriots like Fritz and Shelton. Yet once again, Alcaraz suffered an upset defeat.

Next is the former tournament champion and this year's Indian Wells runner-up, Medvedev. Similar to Alcaraz, Medvedev has consistently performed well at the Indian Wells Masters in recent years, but in Miami, he often reverts to a less dominant form. This time, he lost to the Argentine top player and last year's semifinalist, Cerundolo, which cannot be entirely labeled as an upset. However, as a runner-up just two years ago, Medvedev now seems increasingly distant from claiming this hardcourt title, which is somewhat lamentable.

Defending champion Mensik, who defeated his idol Djokovic in the final last year to claim the title, was momentarily unstoppable. Winning the championship at such a young age was an honor comparable to Nadal's emergence years ago. However, over the past year, he has rarely advanced to deeper rounds in major tournaments. Thanks to his points from last year, he still maintains a ranking within the top 25, but this early exit will cost him heavily in points, and a significant ranking drop is foreseeable. From champion to failing to reach the quarterfinals—for a promising next-generation player, such a落差未免也太大了.

Aliassime, who has already secured several titles this year, is considered on hard courts—where he excels—as a strong contender among the post-2000 generation to share the spotlight with Alcaraz and Sinner. Yet this time, he also exited early. Lack of breakthroughs in major tournaments continues to limit the ceiling of this former benchmark figure among post-2000 players.

We must also mention Tsitsipas, who managed to win only one game. Such feeble performance hardly justifies his past claim of being the "successor to Federer" when he was ranked third.

There are also Draper and Shelton, widely regarded as strong candidates for the third spot. From last year's first Masters title falling... So, can the championship really be considered Sinner's?（来源：网球之家 作者：罗城七爷）
