The Florida native needed just one hour and 30 minutes to seal a resounding 6-1, 6-1 victory, underlining her growing dominance on home soil. Despite being broken in the opening game, Gauff quickly regained control, reeling off 10 consecutive games to dismantle the 13th seed.
The result continues Gauff’s strong record against Muchova, following another straight-sets win over the Czech player earlier this year at the Australian Open.
Speaking after the match, Gauff suggested the contest was more competitive than the scoreline indicated, highlighting the tactical adjustments required when facing familiar opponents.
The victory carries significant ranking implications, with the two-time Grand Slam champion set to climb above Iga Swiatek into world number three in the upcoming WTA rankings.
Gauff will now face either Aryna Sabalenka or Elena Rybakina in Saturday’s final, as she seeks to capture her first Miami Open title.
Reflecting on the milestone, Gauff expressed confidence heading into the final, noting she is ready to test herself against either opponent as she continues her impressive run in front of a home crowd.
