Worst HC player who reached Top 10 in the ATP rankings.

As Casper Ruud enters the Top 10 in the live rankings (unless Sinner beat both Zverev and Novak, Ruud will officially be a top 10 player in the next rankings), is he the player with the worst ever winning percentage on HC to enter the top 10?

He is still young and is primarily a clay-court specialist but his Hardcourt stats are terrible, winning only 21 out of 50 matches (42% win ratio).

Has there been a player reaching the top 10 with worse HC stats than this?

Kent Carlson. Alberto Berasategui. and others. It was not uncommon for many players to play almost exclusively on clay in 80s/90s. it was an era true claycourt specialists(and ranking system was very different - masters were not required events)

also bruguera had pretty much no results on hard when cracked the top 10 in 1991(eventually he improved on that surface)

Maybe some mug from weak era like Gaudio was worse, but Ruud is quite terrible. He doesn’t deserve the place in top 10 after the shameful losses to mugs at USO and especially RG.
Sad we live in an era where ruud is top 10.

He screams ngbs.

Is there anyone (Top 10) with a similar or worse record on HC post-2000 or so, when HC became started becoming more popular?

He's made inroads this season. Consecutive masters QFs, meeting his seeding, that's pretty good for a HC bum.

Felix could also block him by beating Alcaraz and Medvedev/Van de Zandschulp
