Hawk-eye live=no linesmen/women

[dumbdumb]

ATP, WTA, and now major tournament except the 2 Major Courts at US Open using Hawk eye only. pretty much no challenges and just go with Hawkeye for ATP. 2 Major Courts using lines people and challenge system.

No lines persons equals no way/path to get to chair umpire. Chair official only in future probably till they figure out how to eliminate those. Top chairs get (175k plus for most experienced Gold cards/ badge) and expenses per year.

[Umpire in Chief]

Is Hawk-Eye the same system they used in the Atlantic League last year and the Arizona League?
