2006

2006 was a breakthrough year for Becker. In June of that year, he qualified for Wimbledon and defeated Juan Ignacio Chela, before losing in the second round to Fernando Verdasco. At the 2006 US Open, he defeated Filippo Volandri and No. 30 seed Sébastien Grosjean to reach the third round, where he defeated former world No. 1 Andre Agassi in four sets. The match was especially noteworthy as it was Agassi's last on the ATP circuit; he had announced that the 2006 U.S. Open would be his final tournament, and his defeat was followed by an 8-minute standing ovation from the Arthur Ashe Stadium crowd. The day after Becker's win over Agassi, his own U.S. Open bid was ended by Andy Roddick in the fourth round.

Becker has the distinction of having played the match that finished second latest in ATP history, defeating Jiří Novák in Tokyo in 2006 at 3.24 a.m. Following the 2006 U.S. Open, Becker confirmed his status as a promising newcomer on the ATP Tour, improving his ranking from No. 421 at the beginning of the year to No. 62 in November 2006. As a result, Becker received the Newcomer of the Year award during the 2006 ATP Awards and won the Sportsman of the Year award in his part of Germany. After completing his first season on the ATP Tour, Becker made the fastest rise of any player into the top 50.^[4]

2007

2007 saw Becker improving his ranking further in the early season, including through his semi-final appearances at the Delray Beach International Tennis Championships, where he lost to world No. 8 James Blake; and in San Jose at the SAP Open where he lost to Ivo Karlović, the tallest player on the ATP Tour (6' 10"). As a result, Becker's ATP ranking peaked at No. 38 in March 2007. However, in 2007 Becker was unable to progress beyond the first round in any of the Grand Slams or ATP Masters Series events, with the exception of the Monte Carlo Masters, where he lost in the second round to Thomas Johansson.

Given his strong performance at the U.S. Open in the preceding year, Becker's first round loss in the 2007 edition caused his ranking to drop to 79. Despite good form in Bangkok, where he lost in the finals to Dmitry Tursunov, Becker finished the year ranked 84th.
