 Fish was the first to use technology to challenge a line call |
American Mardy Fish became the first player in Grand Slam history to employ instant replay technology to question a line call at the US Open on Monday. The 2006 event is the first of the majors to use the Hawk-Eye system to review controversial decisions.
Fish challenged a shot, hit by his opponent Simon Greul, which landed close to the line but was called good.
Fish, allowed two challenges per set, called for the replay which showed the line judge's decision was correct.
"It was close. I figured it was in," said Fish. "I felt like I still had two challenges. Might as well use it."

The replay was shown to players, officials and fans on a screen at the Louis Armstrong Stadium, allowing everyone to review the video together.
The new technology was launched in March for all US Open Series event and was deemed so successful that it was given the green light for the US Open itself.
In addition to the two challenges per set, players are also allowed an additional one during the tie-break.
If a player is proven to be correct then they retain two challenges, but if they are wrong then one of the challenges is lost.
Despite losing the call, Fish went on to win the match 6-4 6-4 1-6 6-3.
Andy Roddick gave his full backing to the new system after his first-round win over Florent Serra.
"I like everything about it," said Roddick. "Personally, for me, I think it's a good thing because I spend less time whining about calls."
