NEWPORT, R.I. -- Top-seeded John Isner used his blistering serve to overcome scorching conditions and win a title for the fourth time on Newport's grass courts, beating No. 7 seed Alexander Bublik 7-6 (2), 6-3 on Sunday at the Hall of Fame Open.
It was the 34-year-old American's 15th ATP title overall. He also won at Newport in 2017, '12 and '11.
The 22-year-old Bublik played in his first ATP final.
The match started in blazing sunshine with a temperature of 85 degrees temperatures that felt like 95.
Isner was sidelined from April through June after breaking his left foot in the second set of the Miami final, where he lost to Roger Federer.
