Over the years, I have seen a great number of players make spectacular plays. Fielding a bunt and throwing between the legs to first. Fielding a ground ball and throwing behind the back to second. Wood and Prior reaching behind their back to catch a line drive. Fielders throwing while sitting to turn a hit into an out. They are always fun to watch, whichever team makes the plays.
But I have never seen a single player make so many unbelievable plays that it becomes a pattern of play, until Baez came around. I have never even heard of the suggestion that "tagging" could be a talent or skill. Not since Maury Wills have I seen "tag evasion" used on a routine basis.
When you combine these actions with outstanding fielding and better than average offensive abilities, it makes Baez a unique talent that is not likely to be duplicated in my lifetime, nor that of those much younger than myself. The Cubs would be foolish to let him become a free agent at this stage of his career. He makes baseball fun to watch again.
