Bonzi Tops Wins Leaderboard
Benjamin Bonzi was a dominant force on the ATP Challenger Tour in 2021. The Frenchman amassed a tour-leading 50 match wins this year, joining the exclusive '50 Wins Club' in a single season. In the history of the Challenger circuit, only seven other players have won as many matches in a campaign. He concluded his breakout season with a 50-13 record, soaring to a career-high No. 60 in the FedEx ATP Rankings. Argentina's Tomas Martin Etcheverry finished a close second, posting 49 wins.

Meanwhile, Jenson Brooksby was the most consistent performer, boasting an 88.5 win percentage (min. 25 matches played). The American star took full advantage of his opportunities, claiming 23 of 26 matches played in 2021. Sebastian Baez (86.3) and Tallon Griekspoor (85.7) were the only other players with at least 80 percent matches won.

Baez, meanwhile, became the winningest player age 20 & under in Challenger history. His 44 match wins are the most in a single season for a player before their 21st birthday.

Griekspoor Smashes Titles Record
Entering the year, only three players had won six titles in a single season on the ATP Challenger Tour. But in 2021 alone, an additional three players matched that record, with Griekspoor (8), Bonzi (6) and Baez (6) lifting trophy after trophy.

The 25-year-old Griekspoor captured the record for most crowns in a season with his victory in Tenerife, Spain. He would add an unprecedented eighth piece of silverware with a title the following week in the Slovak capital of Bratislava. In fact, since falling to Novak Djokovic at the US Open, the Dutchman did not lose another match for the rest of the year. He would reel off five straight titles on the ATP Challenger Tour in October and November, dominating on the clay of Murcia and Napoli I & II, before moving to the hard courts of Tenerife and Bratislava. His 25-match win streak is the longest in Challenger history.

Bonzi, meanwhile, set the tone in 2021, becoming the first of the trio to reach the six-title milestone. His victories in Potchefstroom and Ostrava were followed by a 20-match win streak, lifting four straight trophies in Segovia, Saint-Tropez, Cassis and Rennes.

Baez reached a tour-leading nine finals in 2021, all on clay, with titles coming on Chilean soil in Concepcion and Santiago I & II, as well as in Zagreb, Buenos Aires and Campinas.
