John Isner vs. Marcos Baghdatis: Score and Reaction from 2015 BB&T Atlanta Open

John Isner's serve is one of the most lethal weapons in men's tennis, and the towering American parlayed that strength into his first singles title of 2015 on Sunday against Marcos Baghdatis at the BB&T Atlanta Open.

Isner lost only one point on serve in the opening set and didn't let Baghdatis mount any momentum amid a 6-3, 6-3 win at Atlantic Station. This marks Isner's third straight title in Atlanta, where he has plenty of local support as a former college star at the University of Georgia.

A primary reason Isner was so dominant stemmed from Baghdatis' difficulties on his own serve. Baghdatis hit only 34 percent of first serves in play during the first set, so he did well to get three games off Isner under the circumstances.

Erik Gudris of TennisNow logged the unfortunate development Baghdatis endured on set point in his bid to keep the opening frame alive:

It's not as though the hobbled Baghdatis didn't do his best while battling evident physical pain. On serve at 2-1 and struggling to hold, Baghdatis was pushed to deuce but held, highlighted by a 25-shot rally that he ended with a drop-shot winner.

Once Isner broke to go up 4-3 on serve in the second, though, the deficit was too much for Baghdatis to overcome. The pre-eminent champion in Atlanta held thereafter and broke Baghdatis again to close the match out—and lost only two points on serve in the final set.

Tennis World's Andrew Burton weighed in on the lopsided final:

Prior to Sunday's finale, Isner spoke about his prior success at the event.

"Seven years ago, when I heard this tournament was going to come to Atlanta, I figured it was going to be a good thing for me," said Isner, per the Atlanta Journal-Constitution's Doug Roberson. "But not this good."

The U.S. Open Series' official Twitter account logged what Isner said following Sunday's victory:

"

"I obviously like it a lot here," @JohnIsner jokes in his @BBTatlantaopen winner's speech. "I feel at home on this court" #USOpenSeries

Isner has won 10 career ATP singles titles now, but to truly break through and contend more often among the game's elite, he'll have to figure out how to harness his form from Atlanta and translate it to bigger tournaments.

Rene Denfeld of The Tennis Island is skeptical of Isner's ability to thrive moving forward:

With the U.S. Open looming later this month, stateside fans have to be excited about Isner's latest triumph. His run to the quarterfinals at Flushing Meadows in 2011 was his best Grand Slam performance, and the 6'10" American is always a dark-horse threat, thanks to his booming serve.

This was the first singles final for Baghdatis since 2011, and the pressure may have been an underlying factor that caused his game to be off. With Isner serving at a proficient rate to start, there was little Baghdatis could do without his best stuff.

Baghdatis nevertheless has to be pleased with his run in Atlanta. He has had a history of injuries and was ranked as high as No. 8 in the world approximately nine years ago.

Perhaps this is the shot of momentum Baghdatis needs to have a career renaissance of sorts, though he must make sure he's healthy enough before entering his next tournament.
