Re: Lynn Welch - is she nuts?
Working at many tennis tournaments I have seen Lynn in action several times and feel she is an excellent chair umpire. Does not make many rogue overrules and is very accurate. Everyone makes mistakes and with the amount of time she spends in a chair of course she will make a few calls that are not correct. Still if she says a ball is in/out. I would put money on it in Vegas as she is almost always spot on. I do not consider her to make a lot of overrules or corrections but saw her make 4 in a match and hawkeye confirmed all 4 to be correct.
Not all chairs are created the same but Lynn has my confidence.
