The Laver Cup provides three listed singles matches for today: Rafael Jodar (#14) against Alexander Bublik (#21), Jakub Mensik (#15) against Brandon Nakashima (#16) and Casper Ruud (#17) against Francisco Cerundolo (#22). The Mensik-Nakashima meeting is the tightest pairing by the rankings given.

At Challenger level, two matches went the full distance without a break of serve settling the closing sets: Jesper de Jong got past Andrea Guerrieri 3-6 7-6 7-6 in St. Tropez, and in Genova Carlo Alberto Caniato edged Tom Gentzsch 6-3 5-7 7-5. In Buenos Aires, Pedro Boscardin Dias recovered from a 0-6 opening set to beat Franco Roncadelli 0-6 7-6 6-3.

Two San Diego and Buenos Aires results carry today's date: Andres Andrade came from a set down to beat Darwin Blanch 3-6 6-3 7-5, while Juan Carlos Prado Angelo needed far less against Valerio Aboian, winning 6-2 6-1. Both draws also delivered results on 24 September, including Timo Legout over Colton Smith 6-3 6-3 and Alex Barrena over Juan Pablo Ficovich 6-3 7-5.
