Coco Gauff, notwithstanding a prior faux pas of pre-match racket amnesia—a gaffe that elicited wry ribbing from compatriot and fellow quarterfinalist Frances Tiafoe, who himself had previously suffered a similar lapse—cemented her Roland-Garros quarterfinal berth with a commanding straight-sets triumph; the subsequent joshing, with Tiafoe’s playful sobriquet of “Mrs. Mature” met by Gauff’s rejoinder on the perceived exigencies of preternatural composure demanded by professional tennis, ultimately left Gauff disarmed, though she remains poised to confront Madison Keys in an all-American quarterfinal showdown on Wednesday, an encounter colored by Gauff's reflections on the imputed maturity foisted upon her by precocious Wimbledon breakthroughs and a nascent Grand Slam title at nineteen.
