Duje Ajdukovic and American Patrick Kypson ascended to career-highs in the Pepperstone ATP Rankings Monday after they each claimed their second ATP Challenger Tour title of the season this weekend.
Ajdukovic returned to the winners’ circle in Kobe, Japan, where he cruised past home hope Sho Shimabukoro 6-4, 6-2 in the Hyogo Noah Challenger final. Ajdukovic, 22, won three deciding-set matches en route to the title.
The split native won his maiden Challenger title in August in Luedenscheid, Germany and following his title run in Japan, Ajdukovic is at a career-high No. 145 in the Pepperstone ATP Rankings.
Kypson defeated second seed Alex Michelsen 6-4, 6-3 in the Paine Schwartz Partners Challenger final in Champaign, Illinois. The 24-year-old American started the year outside the Top 500 and has now risen to a career-high No. 192 following his first hard-court title.
