The longest ATP Challenger Tour final in history? The first unranked Challenger champion? France's record-breaking 27 titles? All of these occured during the 2023 ATP Challenger Tour season, in which 46 different countries hosted a tournament while witnessing the rapid rise of young stars and the resurgence of Tour veterans.

ATPTour.com reviews key facts and figures to remember from the 2023 ATP Challenger Tour season.

Comesana Collects Most Match Wins
Argentine Francisco Comesana tallied a 45-21 Challenger-match record in 2023, edging countryman Facundo Diaz Acosta by one match for the most wins this season. Comesana, 23, was crowned champion in Vicenza and Liberec. On two separate occasions, Comesana went on hot streaks in which he won 12 of 13 matches across three tournaments.

The 22-year-old Diaz Acosta was not far behind with a 44-16 match record. The Buenos Aires native captured four titles (Savannah, Oeiras, Milan, Montevideo) and hit a career-high No. 93 in August after making his Top 100 debut the previous month.

Francisco Comesana 45-21 2
Facundo Diaz Acosta 44-16 4
Luciano Darderi 42-25 2

Navone Nails Five Titles
Argentine Mariano Navone was unstoppable during the second half of the year. From 19 June to 12 November, the 22-year-old competed in six Challenger finals, triumphing in five of them: Poznan, Santa Fe, Santa Cruz, Buenos Aires and Santa Fe-2.

“In May of last year I was losing in the first round of an M15 and today I have won five Challengers,” Navone said in October. “At that moment it was difficult but to that kid I would tell him to be calm, that good things are going to come.”

Diaz Acosta, Aleksandar Kovacevic, Thiago Seyboth Wild and Alejandro Tabilo all tied for second with four Challenger trophies in 2023.
