1988: Turning professional Sampras turned professional in 1988, at the age of 16, and finished the year ranked world No. 97 after starting the year at No. 893. His first professional match was a loss to
Sammy Giammalva Jr. at the February
Ebel U.S. Pro Indoor in
Philadelphia. However, just one week later, at the
Lipton International Players Championships in
Miami, Sampras defeated two top-40 players, before losing to No. 18
Emilio Sánchez. He did not defeat another top-40 player for almost six months, at which point he defeated No. 39
Michiel Schapers at a US Open warm-up tournament in
Rye Brook, New York. In his first Grand Slam singles match, Sampras lost to No. 69
Jaime Yzaga of
Peru in the first round of the
US Open. Sampras did not advance past the quarterfinals in his next three tournaments, although he did record wins over No. 79
Jim Courier in their first career match-up, along with defeating No. 8
Tim Mayotte.
1989: First major match wins The following year, Sampras slightly improved his ranking to a year-ending No. 81. He lost in the first round of the
1989 Australian Open to
Christian Saceanu and, at that year's French Open, won a Grand Slam singles match for the first time in his career; in the second round he lost to eventual champion and fellow American teenager
Michael Chang in their first career match-up. A few weeks later, Sampras lost in the first round of Wimbledon to
Todd Woodbridge. At the
US Open, Sampras defeated defending champion and fifth-seeded
Mats Wilander in the second round before losing to No. 13
Jay Berger in the fourth round. To end the year, Sampras lost in the first round in four consecutive tournaments.
1990: US Open champion At the Australian Open, Sampras upset twelfth-ranked Tim Mayotte in the first round before losing to thirteenth-ranked
Yannick Noah in the fourth round in four sets. His first professional singles title came in February at the Ebel U.S. Pro Indoor in Philadelphia, where he defeated sixth-ranked
Andre Agassi, eighth-ranked Mayotte, and eighteenth-ranked
Andrés Gómez in the final. This title elevated his ranking into the top 20 for the first time. Sampras finished 1990 at No. 5, having started the year ranked No. 61 just prior to the start of the Australian Open. Sampras did not play in the 1990 French Open and lost in the first round of Wimbledon to
Christo van Rensburg. Sampras played seven consecutive weeks during the North American summer hard-court season. He defeated
John McEnroe in the quarterfinals of the Canadian Open, but then lost to Chang in the semifinals. He also reached the semifinals of the tournament in Los Angeles, where he lost to No. 2
Stefan Edberg. He did not advance past the quarterfinals in his next three tournaments, losing to Chang,
Richey Reneberg, and
Goran Ivanišević. In September, Sampras captured his first Grand Slam title, at the
US Open. Along the way, he defeated sixth-ranked
Thomas Muster in the fourth round and third-ranked
Ivan Lendl in a five-set quarterfinal, breaking Lendl's streak of eight consecutive US Open finals. He then defeated 20th-ranked McEnroe in a four-set semifinal to set up a final with fourth-ranked Agassi. Sampras beat Agassi in straight sets to become the US Open's youngest-ever male singles champion at the age of 19 years and 28 days. He played five more tournaments and won the
Grand Slam Cup to complete his year.
1991: Year-end title Sampras lost in the second round of the French Open (to Thierry Champion) and played "very inconsistently" in losing a second round match to Derrick Rostagno at Wimbledon. Upon entering the
US Open as the defending champion that year, he caused controversy when, after losing in the quarterfinals to
Jim Courier, Sampras said that he was not disappointed and felt relieved that the pressure to defend his title was no longer on him. This led to widespread criticism, which included disparaging remarks from Courier and
Jimmy Connors. Sampras captured the first of his five career titles at the year-end
Tennis Masters Cup.
1992: First Masters title Sampras reached the quarterfinals of the
French Open for the first time, losing to Andre Agassi in straight sets. He made it to the
Wimbledon semifinals, losing a serve dominated four set match to Goran Ivanisevic.
1993: Two major titles, world No. 1 Sampras reached the semifinals of the
Australian Open in January, losing again to Stefan Edberg. In April, Sampras attained the No. 1 ranking for the first time. His rise to the top of the rankings was controversial because he had not recently won any Grand Slam titles. A few days after becoming world number one, Sampras beat world number two Jim Courier in the final at Hong Kong on a final set tie break, serving 15 aces. Sampras allowed Sergi Bruguera to dictate play from the baseline and lost in four sets in the French Open quarter finals. He consolidated his number one ranking in July by claiming his first of seven
Wimbledon titles, beating former world No. 1 and fellow American
Jim Courier in the final. This was followed by his second
US Open title, where he beat Cedric Pioline in the final (Pioline made 45 unforced errors during the three set match). Sampras finished the year as the clear No. 1 and set a new
ATP Tour record that year by becoming the first player to serve more than 1,000 aces in a season.
1994: Australian and Wimbledon titles Sampras won the first of two Australian Open titles in 1994, defeating American
Todd Martin in the final. Sampras was suffering from a stomach ailment as the start of the Key Biscayne final was delayed. Andre Agassi was offered a walkover but declined. Sampras recovered and served 7 aces in his final two service games to win in three sets. Sampras allowed Boris Becker a total of five games in three sets in the Italian Open final and entered the French Open trying to win his fourth consecutive Grand Slam. Sampras failed to become the first man since Rod Laver to win four consecutive Grand Slam titles, losing to Jim Courier in the quarters. Courier's ranking was falling and Sampras had won his previous four matches against him but the clay surface "neutralized Sampras' serve". Sampras then defended his Wimbledon in July, beating Ivanisevic in the final. Criticisms were made about the length of the points, as only three rallies contained more than five shots. Sampras was suffering from fatigue and lost in five sets to Jaime Yzaga in the fourth round of the US Open.
1995: Wimbledon and US titles, world No. 1 In 1995, Sampras battled for the world No. 1 ranking with compatriot Andre Agassi. Sampras experienced one of the most emotional matches of his career against Courier in the quarterfinals of the Australian Open. Sampras' longtime coach and close friend,
Tim Gullikson, had mysteriously collapsed during the tournament and was forced to return to the United States. Gullikson was later diagnosed with brain cancer, to which he succumbed the following year. Saddened by Gullikson's illness, Sampras began visibly weeping during the match when a spectator shouted at Sampras, urging him to win it for Gullikson. Sampras nevertheless managed to defeat Courier, but lost the final to Andre Agassi in four sets.
Paul Annacone took over as Sampras' full-time coach after Gullikson's illness made it impossible for him to continue coaching. Sampras defeated Agassi in the final at Indian Wells and lost to him in the Key Biscayne final on a final set tie break. At the French Open, Sampras lost in five sets in round one to Gilbert Schaller, making 99 unforced errors. He then won his third straight Wimbledon title over
Boris Becker in a four set final in which he served 23 aces and didn't face a break point. "Unfortunately, he owns the Centre Court now. I used to own it a few years back, but it belongs to him now" said Becker afterwards. Sampras lost in the final of the Canadian Masters to Agassi. Sampras faced Agassi in the final of the US Open. Agassi "knew Sampras would have to play excellent tennis to beat him. And he knew that Sampras had done exactly that." Sampras served 24 aces during his four set victory. Sampras advanced to the finals, where he defeated No. 2
Michael Chang in straight sets to defend his US Open title. Sampras finished off the year by claiming the season-ending ATP Tour World Championship for the third time in his career beating Boris Becker in five sets in a match which Sampras said was "one of the best matches I have ever been part of".
1997: Australian and Wimbledon titles In January in the fourth round of the Australian Open on a scorching hot day, Sampras was 4–2 down in the fifth set and a point away from going a double break down against
Dominik Hrbatý, before winning the fifth set. He went on to beat
Carlos Moyá in the final. In July, he won Wimbledon for the fourth time, defeating
Cédric Pioline in the final. Sampras also won singles titles in
San Jose, Philadelphia,
Cincinnati,
Munich, and
Paris, and the
ATP Tour World Championships in
Hanover, Germany. He became the only player to win both the
Grand Slam Cup and the
ATP Tour World Championships in the same year. Sampras lost in the fourth round of the US Open to Petr Korda on a fifth set tie break, despite leading 3–0 in the final set. He had a 10–1 win–loss record against top-10 opponents and was undefeated in eight singles finals. He held the
No. 1 ranking for the entire year and joined
Jimmy Connors (1974–1978) as the only male players to hold the year-end No. 1 ranking for five consecutive years. His prize money earnings of US$6,498,211 for the year was a career high.
1998: Wimbledon title, six straight years No. 1 In 1998, Sampras's No. 1 ranking was challenged by Chilean player
Marcelo Ríos. Sampras failed to defend his
Australian Open title, losing in the quarterfinals to
Karol Kučera, and won
Wimbledon only after a hard-fought five-set victory in the final over
Goran Ivanišević. This was Sampras's only Grand Slam final which went to five sets. Sampras lost in the final of the Cincinnati Masters to
Patrick Rafter. Sampras faced Rafter again in the semifinals of the
US Open, losing in five sets after sustaining injury while leading the match two sets to one, and Rafter went on to win his second consecutive US Open title. Sampras lost another semifinal at the Tennis Masters Cup to eventual champion
Àlex Corretja. Nevertheless, Sampras finished the year as the top-ranked player for the sixth year in a row.
1999: Wimbledon title The year started with a withdrawal from the Australian Open due to fatigue, and Sampras failed to win a title during the early part of the season. However, he then went on a 24-match winning streak encompassing the
Stella Artois Championships,
Wimbledon (equaling
Roy Emerson's record of 12 Grand Slam singles titles),
Los Angeles, and
Cincinnati (a rematch of the previous year's final with Patrick Rafter). Sampras' straight sets victory over
Andre Agassi in the Wimbledon final is often cited as one of the greatest performances in a Wimbledon final. Despite this—on account of a herniated disc in his back forcing retirement at the
RCA Championships and withdrawal from the
US Open—he lost his no. 1 ranking to Agassi the following day, when the ATP Tour rankings were updated. Sampras' ranking was hurt by a combination of withdrawing from the Australian and US Opens, tournaments in which he had strong performances during the previous year, and the resurgence of longtime rival Agassi, putting an end to Sampras' six consecutive years of finishing as world No. 1. Agassi took over the top ranking and held it for the rest of the season, but Sampras recovered and managed to beat Agassi in the
year-end championships for the fifth and final time, enabling him to remain third in the rankings.
2000: 13 majors and return to No. 1 Sampras reached the semifinals of the
Australian Open in early 2000, falling to the eventual champion Agassi in a five-set match. He won the
Ericsson Open for the third time in March. After getting knocked out in the first round at the French Open, he won his seventh and final title at
Wimbledon, battling through tendinitis in his right shin and a painful back injury in the process equalling the then all time gentleman's singles title record of William Renshaw. In the final, Sampras was a set down and 4–1 down in the second set tie break against
Patrick Rafter, but went on to win in four sets. This was his 13th Grand Slam singles title, breaking
the all-time record of
Roy Emerson that had stood for over 30 years. In the
2000 US Open, Sampras overcame
Richard Krajicek in four sets at the quarterfinals (including a comeback from 2–6 down in a tiebreaker), and upcoming star
Lleyton Hewitt in the semi-finals, but lost the final to
Marat Safin. Sampras' run to the final briefly returned him to the No. 1 ranking, but
Gustavo Kuerten ended the year atop the rankings. This would be the last time Sampras was ranked No. 1, extending his ATP record career total to 286 weeks. (The record was surpassed by
Roger Federer in 2012.)
2001: Drop in ranking At the Australian Open, Sampras ended a six-year 13 win streak against Todd Martin, losing in the fourth round in four sets. Sampras' 31-match Wimbledon win streak ended in a five set loss to
Roger Federer, aged 19, in the
fourth round; this was the only time the two ever played against each other in an official professional match. At the
US Open, Sampras reached the final but lost in straight sets to
Lleyton Hewitt. Overall, this season was the first in 12 years that Sampras did not win a single title, and he finished the year ranked No. 10, also his lowest since 1989.
2002: 14th major and retirement Sampras lost in the fourth round of the Australian Open to Marat Safin in four sets. "Muttering, slouching, slamming his racket to the ground and smacking a ball into the stands, Pete Sampras was in typical French Open form" as he lost to Andrea Gaudenzi in round one, a sixth consecutive early loss at Roland Garros for Sampras. He suffered an early exit from Wimbledon too, losing in the second round to No. 145 fast-court specialist
George Bastl of Switzerland. After that loss, Sampras asked his former coach
Paul Annacone to return and coach through the US Open. Sampras had a relatively poor summer leading up to the
US Open, losing at Cincinnati to No. 70-ranked
Wayne Arthurs in the second round, and then was eliminated at the opening round at Long Island by No. 85.
Paul-Henri Mathieu. At the
US Open, Sampras was seeded 17th.
Greg Rusedski, whom Sampras had defeated in a long five-set third round match at the US Open, said that Sampras was "a step and a half slower" and predicted that Sampras would lose his next match. Sampras, however, then defeated two young stars,
Tommy Haas in the fourth round and
Andy Roddick in the quarterfinals. He then defeated
Sjeng Schalken in the semifinals to reach his third consecutive US Open final, and eighth US Open final overall, tying
Ivan Lendl's all-time record. This time, Sampras faced Agassi, whom he had met in his first Grand Slam final 12 years earlier. After a four-set battle between the two veterans, Sampras claimed a then-record 14th Grand Slam singles title and matched
Jimmy Connors' Open Era record of five US Open singles championships. Sampras did not compete in any tour events in the following 12 months, but he did not officially announce his retirement until August 2003, just prior to the US Open. He chose not to defend his title there, but his retirement announcement was timed so that he could say farewell at a special ceremony organized for him at the Open. ==Post-retirement activity==
