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:
“If women were umpiring none of this [rowdyism] would happen. Do you suppose any ball player in the country would step up to a good-looking girl and say to her, You color- blind, pickle-brained, cross-eyed idiot, if you dont stop throwing the soup into me Ill distribute your features all over you countenance! Of course he wouldnt.”
—Amanda Clement (18881971)
“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 (18961966)
“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 (19081973)
“Dust rises from the main road and old Délira is stooping in front of her hut. She doesnt look up, she softly shakes her head, her headkerchief all askew, letting out a strand of grey hair powdered, it appears, with the same dust pouring through her fingers like a rosary of misery. She repeats, we will all die, and she calls on the good Lord.”
—Jacques Roumain (19071945)
