Ivo Karlovic offered further proof that tennis careers can continue blossoming long after players reach their 30s when he became the oldest ATP title winner for 37 years at the weekend.

The 37-year-old Croat outlasted Luxembourg’s Gilles Muller 6-7 7-6 7-6 to win the grasscourt Hall of Fame Championships in Newport, Rhode Island – becoming the oldest champion in the tournament’shistory.

In saving three match points before downing Muller, the big-serving Karlovic became the oldest Tour winner since Marty Riessen (37 years, nine months) in Lafayette in 1979.

It was his third consecutive Newport final, having lost the previous two. Karlovic now has seven career titles, the first coming in 2009.

“After all these years when I was losing in the final and now I was finally able to do it,” world number 35 Karlovic said.

“And I was down a match point. That makes it even nicer.”
