McEnroe echoes Azarenka's call for replays

After a much-debated call in her French Open loss to Serena Williams, Victoria Azarenka suggested perhaps it is time for full-on instant replay to be used in tennis - beyond simply the Hawk-Eye line-calling used at some events.

"Sometimes we need to have a review," Azarenka said, explaining chair umpires could use "a little TV screen" that would also allow them to monitor audio and video.

Not surprisingly, John McEnroe would support that sort of thing.
