Overall he looked pretty worn out and didn't play every point 100% like he usually does. I suspect COVID, which he had in January, may have had lingering effects on him. Also, I must say it's disappointing that AP dropped him altogether. I hate to see that as Stan + AP is an iconic combo.Even if they put him on "senior status", paid a little less, and he still wore an AP in the matches it would be a better way to go out. But who knows, perhaps Stan thinks he can get a bigger endorsement elsewhere. In the same vein, Richard Mille dropped Zverev earlier this year.
