For Isner, who saved set point in both sets,
the win marks his second consecutive title since suffering a
second-round loss at Wimbledon.
The booming serve of Isner, who last week won the Hall of Fame
Open in Newport, Rhode Island, proved to be the difference as
the 32-year-old American won 85 percent of his first-serve
points against his fourth-seeded opponent.
By capturing his 12th title, Isner will move up two spots to
18th in the ATP rankings on Monday and surpass Jack Sock as the
top-ranked American player.
Isner has now reached the Atlanta final in seven of the
tournament's eight years.
