## Season summary

The 2003 ATP Tour season saw 3 new Grand Slam champions and saw Andre Agassi win his eighth and last Grand Slam title when winning the Australian Open for the fourth time. Roger Federer would win his first of 20 Grand Slam titles by defeating Aussie Mark Philippoussis 7–6$^{(7–5)}$, 6–2, 7–6$^{(7–3)}$ in the final at Wimbledon. Federer would also win his maiden Tennis Masters Cup by defeating Agassi in the final 6–3, 6–0, 6–4. Federer would win 7 titles overall, including winning in Dubai and Halle, tournaments he would have a lot of success at in later seasons. 2003 would be a breakout season for Federer as a dominant player at the very top of the game, improving his year-end ATP ranking from 6 the previous season to 2.
Andy Roddick also had a breakthrough season by winning his first and only Grand Slam title at the US Open and ending the season as world No. 1, 160 points ahead of Federer. Roddick started the season off with an epic victory in the quarterfinals of the Australian Open over Younes El Aynaoui, winning 21–19 in the fifth set after playing for 4 hours and 59 minutes. By doing this, Roddick reached his first major semifinal but was eventually defeated by Rainer Schüttler.
Roddick reached the semifinals of Wimbledon where he was defeated by Federer in straight sets but then won his maiden Masters Series title in Montreal, beating Federer in the semis on route. Roddick would then go on to win back to back Masters Series titles by winning Cincinnati. At the US Open, Roddick saved a match point en route to the title in the semifinals against David Nalbandian, which he won 6–7$^{(4–7)}$, 3–6, 7–6$^{(9–7)}$, 6–1, 6–3. He went on to defeat Juan Carlos Ferrero 6–3, 7–6$^{(7–2)}$, 6–3 in the final. Roddick became one of only three players to win Canada, Cincinnati and the US Open consecutively along with Patrick Rafter in 1998 and Rafael Nadal in 2013.
Juan Carlos Ferrero also added his name to the list of maiden Grand Slam champions in 2003 when he won the French Open, having lost in the final the previous year. He defeated surprise finalist Martin Verkerk 6–1, 6–3, 6–2. Ferrero also captured Masters Series titles in Monte Carlo and Madrid and went on to end the season as world No. 3.
Andre Agassi won his eighth and final Grand Slam title by defeating Rainer Schüttler in the final of the Australian Open 6–2, 6–2, 6–1. In March, Agassi won his sixth Miami Masters title and his 16th Masters title overall. On April 28, Agassi reclaimed his position at the top of the ATP rankings for the first time since 2000. He then replicated this feat when recapturing the No. 1 ranking on June 16, a position he maintained for 13 weeks. By being No. 1 in the rankings, he became the oldest world No. 1 at 33 years and 3 months of age, a record not broken till Federer got to the top of the rankings in 2018. Agassi lost in the semifinals of the US Open to Ferrero.
Young Argentine Guillermo Coria had a breakout season in 2003, rising from world No. 45 in 2002 to 5 at the end of the year. He won his first Masters Series title in Hamburg and reached the semifinals of the French Open. Félix Mantilla caused an upset by capturing his first and only Masters title in Rome, picking up wins over Costa, Kafelnikov and Federer on the way. 4-time Wimbledon semi finalist Tim Henman also captured his lone Masters Series title by impressively coming through the draw in Paris, defeating the likes of Federer and Roddick on the way before defeating Andrei Pavel in the final.
2002 Wimbledon champion Lleyton Hewitt’s form dropped in 2003, losing his world No. 1 position and dropping out of the top 10. Despite failing to reach a Grand Slam semifinal in 2003, Hewitt did however defend the title at the Indian Wells Masters and was instrumental in helping Australia win the Davis Cup title. Hewitt defeated Federer in the semifinals from 2 sets down to help Australia reach the final. He then defeated Ferrero in the final in another 5 set victory to help Australia capture their 28th Davis Cup crown. Mark Philippoussis beat Ferrero to see Australia claim the victory over Spain 3–1 in Melbourne.
