Player Challenges of Line Calls
In 2006, the US Open introduced instant replay reviews of calls, using the Hawk-Eye computer system sponsored by Chase. Each player is allowed three challenges per set plus one additional challenge during a tiebreak. The player keeps all existing challenges if the challenge is successful. If the challenge is unsuccessful and the original ruling is upheld, the player loses a challenge. Instant replay was initially available only on the stadium courts (Ashe and Armstrong), until 2009 when it became available on the Grandstand as well.
Once a challenge is made, the official review (a 3-D computer simulation based on multiple high-speed video cameras) is shown to the players, umpires, and audience on the stadium video boards and to the television audience at the same time. During the 2011 US Open, 29.78% of men's challenges and 30.2% of women's challenges were correct.
In 2007, JP Morgan Chase renewed its sponsorship of the US Open. As part of its sponsorship arrangement, Chase renamed the tournament's replay system the "Chase Review" on in-stadium video and television.

Famous quotes containing the words player, challenges, line and/or calls:
“Abused as we abuse it at present, dramatic art is in no sense cathartic; it is merely a form of emotional masturbation.... It is the rarest thing to find a player who has not had his character affected for the worse by the practice of his profession. Nobody can make a habit of self-exhibition, nobody can exploit his personality for the sake of exercising a kind of hypnotic power over others, and remain untouched by the process.”
—Aldous Huxley (1894–1963)
“The approval of the public is to be avoided like the plague. It is absolutely essential to keep the public from entering if one wishes to avoid confusion. I must add that the public must be kept panting in expectation at the gate by a system of challenges and provocations.”
—André Breton (1896–1966)
“The real dividing line between early childhood and middle childhood is not between the fifth year and the sixth year—it is more nearly when children are about seven or eight, moving on toward nine. Building the barrier at six has no psychological basis. It has come about only from the historic-economic-political fact that the age of six is when we provide schools for all.”
—James L. Hymes, Jr. (20th century)
“Anyone can see that to write Uncle Tom’s Cabin on the knee in the kitchen, with constant calls to cooking and other details of housework to punctuate the paragraphs, was a more difficult achievement than to write it at leisure in a quiet room.”
—Anna Garlin Spencer (1851–1931)
