My boy Medvedev has played 53 matches on the main tour this year, only three against top ten and twelve in the top twenty (6-6 record)

This looks like a case of inflated stats no doubt

Though Tokyo has looked impressive from the opponents he's played and the accounts from a few posters who have watched Daniil this week.
I think a top ten placing is a bit too much right now.
I wasn't being overly serious about not watching Daniil on replay, if the match up is interesting and it's deep in a tournament, I'll possibly watch it.
He's beaten 4 in the top 20 and gave a peak form Thiem a close, close match. In Tokyo he's at 55.1% points won with 70% on serve and 41% on return. Ninja is higher due to superlative 47% won on return points fueled by over 60% on 2nd return points. If Med serves well again with less 2nd serve points this won't matter as much and Ninja only managed 30% on first return with Gasquet. Medvedev won 80% of his first serve points against Shapo so if Kei dips much below 30% on first return he may not break so much. Medvedev has been at 35 to 40% on first return points this week accept with Raonic who was absolutely goating on serve until the break in the 2nd set. Kei is going to see a lot more break points in this match on serve; don't see him winning 85% of first serve points like the last two matches.
