Should the tour have an official review system?
Obviously, we have the hawkeye challenge system that players can use. Each player gets 3 challenges per set and an extra one in the tiebreak.
But what if a player runs out of challenges by the end of the set, and on set/match point a controversial line call is made?? Sometimes players get robbed of matches and sets on points like these. Should the tour have a review systems that chair umpires can use to review critical points in matches?
What do you guys think?
