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:
“There has been in our time a lack of reliance on language and a lack of experimentation which are frightening to anyone who sees them as symptoms. We know the phenomenon of stage-fright: it holds the player shivering, incapable of speech or action. Perhaps there is an audience-fright which the play can feel, which leaves him with these incapacities.”
—Muriel Rukeyser (1913–1980)
“A powerful idea communicates some of its strength to him who challenges it.”
—Marcel Proust (1871–1922)
“Our job is now clear. All Americans must be prepared to make, on a 24 hour schedule, every war weapon possible and the war factory line will use men and materials which will bring, the war effort to every man, woman, and child in America. All one hundred thirty million of us will be needed to answer the sunrise stealth of the Sabbath Day Assassins.”
—Lyndon Baines Johnson (1908–1973)
“For in this yellow grave of sand and sea
A calling for colour calls with the wind
That’s grave and gay as grave and sea
Sleeping on either hand.”
—Dylan Thomas (1914–1953)
