Nuno Borges Stuns Barcelona Crowd With Underarm Ace to Oust Etcheverry

In a match defined by tactical audacity and a polarizing finish, Nuno Borges secured his spot in the quarterfinals of the Barcelona Open Banc Sabadell on Wednesday, April 15, 2026. The Portuguese star closed out the contest against Tomas Martin Etcheverry with a daring underarm serve ace on match point, a move that left the spectators at Pista Rafa Nadal in a state of shock.

The finish was a stark contrast to the preceding rally. Etcheverry had managed to save the first match point, firing back a return winner against Borges, who had been employing a serve-and-volley strategy throughout the match. But, Borges responded to the setback with a provocative ploy that caught the Argentinian completely off guard.

Underarm serves are perfectly legal within the rules of tennis, but they often trigger strong reactions from crowds and opponents alike due to their perceived lack of traditional etiquette. In this instance, the tactic worked perfectly, sealing the victory for Borges and drawing a mixture of gasps and mixed reactions from the Barcelona crowd.

Tactical Audacity at Pista Rafa Nadal

Borges’ decision to go underarm was not just about the point, but about the psychology of the moment. By shifting the rhythm and depth of the serve, he neutralized Etcheverry’s positioning, leaving the opponent unable to reach the ball. For those unfamiliar with the nuance of the game, the underarm serve is typically used to exploit a returner who is standing deep behind the baseline to anticipate a powerful first serve.

The match took place at the prestigious Pista Rafa Nadal stadium in Barcelona, Spain, as part of the ATP 500 event. The atmosphere, usually supportive of traditional baseline grinding on the clay, was momentarily disrupted by the unconventional nature of the match-winning shot.

As Editor-in-Chief of Archysport, I have covered numerous Grand Slams and ATP events over the last 15 years, and whereas underarm serves are becoming more common in the modern era, using one to seal a quarterfinal berth in a high-pressure environment remains a high-risk, high-reward gamble. Borges’ willingness to embrace that risk defines the current shift in tactical aggression on the tour.

What This Means for the Tournament

With this victory, Nuno Borges advances to the quarterfinals of the Barcelona Open. His ability to blend a serve-and-volley approach with unconventional shot-making makes him a dangerous opponent on the clay courts of Spain, where patience is usually the primary virtue.

For Tomas Martin Etcheverry, the loss is a disappointing exit from a tournament where he had shown resilience, specifically in his ability to counter-punch against Borges’ aggressive net rushes until the final, unexpected point.

Borges will now look to carry this momentum into the next round, where his unpredictable style will continue to test the adaptability of his upcoming opponents. Fans and analysts will likely be discussing the “underarm ace” for the remainder of the week, reflecting the ongoing debate between traditional tennis decorum and modern competitive strategy.
