Re: Will Barty be one of the most consistent #1s in history?
To second what everyone's said, Chris Evert played 56 majors and lost before the SFs only 4 times (twice in the QF), so it's a tough task.
In fact, it would be an interesting exercise to go through the list of YE #1 players to see what their results were that season. # of losses, slam record, # of titles, etc. Don't have the time now, but I'll make a project of it sometime soon.
