Permit me to give non-critical, objective (non-NY) view. I don't live near New York, so I've never had to see Suzyn.
Yesterday I tuned in to the Yankees broadcast on XM Radio and heard Suzyn. I didn't find her to be "screechy" at all. She knew her stuff and went to a lot of effort to find out about some of these minor leaguers (for both teams) that were entering the game in the late innings.
Give her a chance, guys. From comments I've read, be thankful you don't have to look at her any more!
