STOCKHOLM — John Isner was taken all the way by fellow American Bradley Klahn before winning his first match of the week at the Stockholm Open on Thursday.

The top-seeded Isner, who can still qualify for the end-of-season ATP Finals in London, toughed out a 7-6 (2), 6-7 (5), 7-6 (5) victory in the second round after receiving a bye in the first round.

Isner led 5-0 and 6-2 in the final-set tiebreaker but Klahn, ranked No. 102, pulled the score back to 6-5. Isner then produced a big first serve on his fourth match point, which Klahn couldn’t return.

"Who knows? Maybe I needed a match like this to get me going," said Isner, who fired 31 aces. "I think I was pretty fortunate tonight."

It was his first competitive match since losing to Juan Martin del Potro in the U.S. Open quarterfinals in early September. He has since become a father.

Fabio Fognini, the second seed, beat Lukas Lacko 6-4, 6-4, and there were also wins in the second round for Philipp Kohlschreiber and Tennys Sandgren.
