America's Sam Querrey was 2 points from defeat before battling back to win the ATP 500 title in Memhpis against compatriot and good friend John Isner.
Both men held serve with ease in the 1st set, and the set had to be decided on a tiebreaker, Isner managed to play some very attacking tennis and he was rewarded as he won the set 7-6.
The second set followed a very similar pattern and once again it had to be decided on a tiebreaker, at 5-2 up in the shoot out, Isner appeared to be on course to win his 2nd title of the year, but Querrey won the next five points to win the tiebreaker and level the match at one set all.
Querrey then took his game up another level against a clearly deflated Isner, and the Californian broke Isner twice in the 3rd set to win it 6-3 and take the title, with a 6-7 7-6 6-3 victory, it is the 3rd ATP title of Querrey's career.
Isner and Querrey will later team up in the doubles final.
