From 1990 through 2012, inclusive, only two men aged 35+ won tour titles: Andre Agassi and Fabrice Santoro. But in the last five years, six men aged 35+ have done so: Tommy Haas (last title: Vienna 2013, when he was 35), Ivo Karlovic (last title: Los Cabos 2016, when he was 37; last final: s-Hertogenbosch 2017, when he was 38), Victor Estrella Burgos (last title: Quito 2017, when he was 36), Feliciano Lopez (last title: London Queen's 2017, when he was 35), David Ferrer (last title: Bastad 2017, when he was 35), and of course Roger Federer (last title: Basel 2017, when he was 36). [I list the players in chronological order of the last title that they won]. Will this trend continue in 2018? Federer will most likely win further titles, but will any other men aged 35+ do so? Besides the ones who have already won titles aged 35+, the following men still active on tour either are 35 or turn 35 next year: Paolo Lorenzi, Julien Benneteau, Mikhail Youzhny, Gilles Muller (turns 35 in May), Philipp Kohlschreiber (turns 35 in October), Fernando Verdasco (turns 35 in November), Florian Mayer (turns 35 in October), Guillermo Garcia-Lopez (turns 35 in June), Yen-Hsun Lu (turns 35 in August), Nicolas Mahut, Carlos Berlocq (turns 35 in February), and Tommy Robredo. Several lower-ranked players such as Paul-Henri Mathieu still regularly compete in qualifying, too.
