Calleri stuns world No. 1 Ferrero in 2003 Davis Cup upset
On September 21, 2003, Argentina's Agustin Calleri, ranked 16th, shocked world No. 1 Juan Carlos Ferrero in straight sets during the Davis Cup semi-finals.
Argentina's Agustin Calleri delivered a stunning Davis Cup performance against the world's top-ranked player on September 21, 2003. According to Tennis Majors, Calleri, who was not originally slated for singles, defeated Spain's Juan Carlos Ferrero 6-4, 7-5, 6-1 in the semi-final tie held in Malaga.
Calleri struck an extraordinary 109 winners during the three-set match. This unexpected victory leveled the overall team score at 2-2, reviving Argentine hopes after Spain had dominated the opening days. The world No. 1 Ferrero, the reigning Roland Garros champion, was considered the best clay-court player globally at the time.
The Context of the Semi-Final
Spain entered the 2003 Davis Cup semi-final as the heavy favorite. Their team featured three former Roland Garros champions: Ferrero (world No. 1), Carlos Moya (No. 6), and Albert Costa (No. 22). Argentina was missing two of its top players, Guillermo Coria and David Nalbandian. The responsibility fell to Calleri (No. 16), Mariano Zabaleta (No. 24), and Gaston Gaudio (No. 32).
Spain took a commanding lead on the first day. Ferrero defeated Gaudio decisively, and Moya mounted a comeback victory over Zabaleta. On Saturday, Calleri and doubles partner Lucas Arnold Ker kept Argentina alive with a win. This set the stage for Calleri's Sunday showdown with Ferrero.
Calleri's Flawless Performance
The task seemed nearly impossible for the Argentine. Ferrero claimed a dominant 111-25 record on clay since 2000 and was the recent French Open champion. Calleri, aged 27, had never progressed past the third round of a major. Yet, from the start, Ferrero appeared uncharacteristically nervous.
Calleri seized the opportunity, playing aggressive, risk-taking tennis. He use his signature jumping one-handed backhand to great effect. After securing the first set, he fought back from a 5-3 deficit in the second. He then dominated the third set, racing to a 4-0 lead before closing out the match. His 109 winners in a three-set match represented what he later called his career's biggest achievement.

The match pitted a player at his peak against one enjoying a career-best season. The following table summarizes their key achievements leading into the 2003 Davis Cup semi-final.
| Player | 2003 Year-End Ranking | Notable 2003 Achievements | Career Peak Ranking (Date) |

The Aftermath of the Upset
Despite Calleri's heroic effort, Spain ultimately won the semi-final. In the decisive fifth rubber, Carlos Moya defeated Gaston Gaudio. Spain then lost the final that year to Australia. The 2003 season remained Calleri's best on tour; he never surpassed his ranking of world No. 16 or reached a Grand Slam fourth round.
Ferrero's reign at No. 1 lasted only eight weeks before Andy Roddick supplanted him. He left the top 10 in 2004 and did not return. The Spaniard, nicknamed "El Mosquito," later transitioned to coaching, where he now guides Spanish star Carlos Alcaraz.
