MEMPHIS, Tenn. -- Four months ago, Sam Querrey thought his tennis career might be over. On Sunday, he took it to a new level.
The only drawback? He had to beat his best friend, doubles partner and future Davis Cup teammate John Isner, in the Morgan Keegan Championships to do it.
"I'm sure we'll joke about it later," Querrey said after his 6-7 (3), 7-6 (5), 6-3 win.
Querrey was seriously injured in October in Bangkok after falling through a glass coffee table and suffering a cut to a muscle in his forearm that required 25 stitches to repair.
He was just centimeters away from permanent, potentially career-ending damage, doctors told him, and carries a nasty, 2-inch scar. After six weeks away from the game, then rehabilitation over the winter break, Querrey has made quite the return.
The world's No. 31 player will jump to the high 20s next week and wiped away any questions left by the injury with a week that would be the envy of any player.
Then he beat Roddick in the quarterfinals in Memphis on Friday, clearing the way for Sunday's friendly final.
The pair ate steaks together the night before the finals (Querrey lost a bet and had to pay), warmed up together Sunday morning and stuck to the same old routine -- until it came time to actually face off.
"This is the first match we've played," Querrey said. "Hopefully over the next 10 years we'll play 10 or 15 times. I'm sure I'll win some and he'll win some."
As expected in a match featuring friends, Isner and Querrey played swing for swing much of the afternoon until Querrey rallied from three points down in the second tiebreaker to start a run. Two points from defeat, Querrey won five straight points, then broke Isner twice in the third set for his third career title and first this season.
As expected in the tallest finals matchup in ATP history -- Isner is 6-foot-9, Querrey 6-6 -- both players' serves were dominant.
Querrey fought off three break points early in the match, including two in the first set, and was never broken. He finally got to Isner to go up 2-1 in the third, then broke his serve again to end the match.
Isner took control early in the second tiebreaker, building a 5-2 lead on Querrey's error on an easy return. Querrey screamed, "Oh, God!" as the ball deflected off the edge of his racket and sailed wide.
Rather than derail him, though, the error seemed to invigorate him and he went on to win five straight points. He started with an ace to pull within 5-3. Isner hit the ball into the net on a return, then was long on the next point -- his first real mistake on his own serve -- to make it 5-all.
Querrey chased down a drop shot by Isner and sent a forehand crosscourt to take a 6-5 lead before Isner again hit the ball long after a volley that featured some of the day's best back-and-forth action.
"I think it's a completely different mindset if I'm up 6-5 instead of down," Isner said.
Isner's formidable first serve began to falter in the third set. He hit 78 percent of his first serves in the first set and 65 percent in the second, but that dropped to 48 percent in the third.
Querrey's serve went in the opposite direction. He hit just 48 percent in the first two sets, but that spiked to 73 percent in the third.
Querrey broke Isner for the first time when Isner sent the ball into the net on an unforced error in the third.
Isner, a two-time champion who won in New Zealand earlier this year, was disappointed he lost, but acknowledged it wasn't as painful as it could have been because of the opponent.
The two live on opposite coasts in the offseason, but are in constant contact on tour and off.
"We honestly probably text every day," said Isner, who lost for just the second time this season. "You don't want to know what we text about."
