John-Patrick Smith, receiving a wildcard into the
Australian Open. It was here that Peers gained his first Grand Slam victory, upsetting the Polish duo of
Mariusz Fyrstenberg and
Marcin Matkowski in their opening match; in the second round they fell to
Sergiy Stakhovsky and
Mikhail Youzhny in straight sets. In February, Peers teamed up with established doubles specialist
Jamie Murray, a partnership that immediately looked to be a successful one, as the pair reached the semifinals of their first tournament together at the
Open Sud de France. A couple of months later, Peers and Murray won their first title together, defeating 13-time Grand Slam champions and world No. 1 pair
Bob and Mike Bryan in the final of the
U.S. Men's Clay Court Championships after coming back from a set down. The pair played their first Grand Slam tournament together at the
French Open, however despite taking out the 15th seeded team of
Knowle and
Polášek in the first round, they ultimately fell in their next match against the Colombian duo of
Juan Sebastián Cabal and
Robert Farah Maksoud. This however allowed them to compete at the
Aegon Trophy, a Challenger event which they ultimately won. Peers and Murray then went on to have a fairly successful grass court season, reaching the quarterfinals of the
Aegon Championships, and the semifinals of the
Aegon Championships. They headed to
Wimbledon in a confident mindset, however, went out in the first round to
James Blake and
Jürgen Melzer in a 5-set thriller that ended 14–12 in an 87-minute final set. Their early loss did not dishearten them however, and the pair went on to win their second title of the year a few weeks later, at the
Crédit Agricole Suisse Open Gstaad. At the
US Open, the pair had their most successful run at a Grand Slam tournament, making it all the way to the quarterfinals, defeating ninth seeds
David Marrero and

Daniell already in the round of 32. In Halle Kontinen/Peers lost at the semifinals to
Kubot/
Peya. This prepared the players for the grass courts of
Wimbledon, where they were to achieve their best Grand Slam tournament result so far. As 10th seeds the couple finally defeated Bopanna/Mergea by winning 8–6 the 5th set of the third round match. However, the pair's destiny was to get defeated in the next round by the top seeds
Herbert/
Mahut. Peers and Kontinen continued in
Hamburg at the 500 series tournament. They played without dropping a set all the way to the final, to play against

Shanghai Masters the pair performed better, beating the 8th seeded Lindstedt/Pospisil in the second round and the top-seeded Myrray/Soares in the quarterfinals. By defeating the unseeded
Čilić/
Pavić in the semifinals they were one step away from winning the tournament, but their final opponents
Isner/
Sock grabbed the title with more relaxed playing. Peers and Kontinen then appeared at the
Swiss Indoors, where they lost in the first round to second seeds
Herbert/
Mahut in straight sets. One week later at the
