Instant replay system is coming (really)

It looks like we're finally going have a chance to see what happens when a challenge system is used in major tournaments.

Players at some tournaments, beginning with the Nasdaq-100 beginning March 20 in Miami and including some US Open Series tournaments and the U.S. Open, will be able to challenge a line call and see the result of the challenge on giant screens with a instant-replay ball tracking system.

By limiting players to two unsuccessful line-call challenges per set, plus one more in a tiebreak, organizers are hoping to give players a recourse for bad calls while avoiding unnecessary delays to the game and possible gamesmanship by players hoping for a little rest or to break another player's rhythm. If a player wins a challenge, that player retains the challenge. There's an element of strategy as players may want to save their challenges for only the most crucial points.

Lots of players have comments included in this article, including James Blake, Roger Federer, Andy Roddick, and Lindsay Davenport. I hate bad calls, even though they have been a part of tennis forever, so I am looking forward to seeing how well this goes. For me, it is a step in the right direction.
