I think Sinner has *plenty of upside*- more than anyone else in the picture at this time,What truth? Your subjective opinion is not truth. You calling him Berdych doesn't make him Berdych. Lemme tell you the truth he's a slam champion and unbeaten for months and has an excellent top 5 records and he's set to dominate and become ATG and make you cry.
while we wait somewhat impatiently for the next OHBH Great (there will be one).
