Carlos Alcaraz just earned another title -- most expensive racket ever sold at auction -- 'cause the tennis superstar's 2023 Wimbledon Finals equipment just went to a new owner for a whopping $173K!!!
Bidding on the incredible piece of memorabilia ended Sunday night ... and the final price surpassed the $157K mark set by Nadal's 2017 French Open Championship racket, which held the record for just a few months.
Prestige Memorabilia -- which listed the piece -- was able to photomatch the racket to 10 dates .
