DecoTurf is a tennis hardcourt comprising layers of acrylic, rubber, silica, and other materials on top of an asphalt or concrete base. It is manufactured by Decosystems, which is a division of California Products Corporation which also manufactures Plexipave, based in Andover, Massachusetts.

The surface is currently in use at the US Open (where, in 2011, heavy rains caused water to bubble up through the court surface in Louis Armstrong Stadium), the ATP World Tour Masters 1000 events at Canada Masters and Cincinnati Masters, as well the US Open Series tournaments. DecoTurf was used in the 2008 Olympics held in Beijing, China and 2004 Olympics held in Athens, Greece.

Compared to Rebound Ace, which was previously used for the Australian Open from 1988 until 2007 but has since been replaced, tennis balls slow down slightly less upon impact with DecoTurf and bounce slightly lower. This probably explains why serve-and-volley players such as Stefan Edberg, Tim Henman, and Patrick Rafter had more success at events held on DecoTurf than at other hardcourt events.

By winning three Majors in 2011, Djokovic became the sixth male player in the open era to win three Majors in a calendar year.

He is the first male player representing Serbia to win a Major singles title and the youngest player in the open era to have reached the semifinals of all four Grand Slam events, separately and consecutively. Amongst other titles, he won the Tennis Masters Cup in 2008 and was on the team which won the 2010 Davis Cup. He also won the bronze medal in singles at the Beijing Olympics in 2008.

Mikhail Mikhailovich Youzhny (Михаил Михайлович Южный [mixaˈil ˈjuʒnɨj] ( listen); born 25 June 1982, in Moscow, Russia, is a professional Russian tennis player, noted for his consistency and all-court play style. He has been coached by Boris Sobkin for 17 years.

The highest singles world ranking of his career was number eight, achieved 28 January 2008 and again on 18 October 2010.

Mikhail began playing tennis at six with his older brother, Andrei, a pro futures player in 1998–2000. At 13, he was a ballboy for the Russia – U.S. Davis Cup matches.

Youzhny has a unique backhand, in which he mainly hits one-handed, but also has somewhat of a hybrid reminiscent to that of Björn Borg. Youzhny at times will follow through his backhand with both hands, but with only his right hand on his racket. Even so, many consider his backhand to be his best shot. From both sides, Youzhny hits the ball on the rise, achieving a flatter trajectory. He has a good court sense and often makes use of dropshots.

Youzhny has a reputation for engaging the crowd, subsequently taking inspiration from it to attempt high-risk winners, especially when facing matchpoints. After each big victory Youzhny gives a military style salute to the spectators. He does it by holding the tennis racquet above his head with his left hand and saluting with his right hand. The racquet imitates a hat, since according to Russian military tradition one must wear a hat to give proper salute.
