Teen Titlists (8)
Seven different teenagers accounted for a total of eight Challenger titles this year, with Felix Auger-Aliassime the lone player to win multiple crowns (Lyon, France & Tashkent, Uzbekistan). At 17 years, 10 months, his repeat victory in Lyon made him the youngest player to successfully defend a title. And in October, the Canadian became the second-youngest player to win his fourth Challenger crown, behind only Richard Gasquet.

Germany's Rudolf Molleker became the youngest champion of the year, at 17 years and six months, on home soil in Heilbronn. Austrian teen Jurij Rodionov is the youngest from his country to lift a trophy since 1986, triumphing in Almaty, Kazakhstan. 

It was also the third straight season in which a teenager reached a final on both the ATP World Tour and ATP Challenger Tour. Alex de Minaur followed in Taylor Fritz (2016) and Andrey Rublev's (2017) footsteps in achieving the feat.

Simon Strikes 52 Aces In Ortisei
Tobias Simon was a serving machine at the Sparkasse Challenger Val Gardena. In the final round of qualifying, he would produce a masterclass on the indoor hard courts of Ortisei, Italy. A total of 52 aces erupted from his racquet, as the German advanced to the main draw with a three tie-break win over Aldin Setkic.

All-time ace stats do not include ATP Challenger Tour qualifying. But, to put the achievement in perspective, the ATP Tour record is 45 by Ivo Karlovic in Halle in 2015.

Title Leaders By Country
Players from 38 countries won titles this year, with Hugo Dellien becoming the first from Bolivia to lift a trophy since 1983. Australia and the United States boasted a tour-leading 17 winners apiece, with 12 different champions from each nation.
