## Professional career
### 2013

Peers began the 2013 season playing with fellow Australian 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 Fernando Verdasco on the way. In the end, the pair succumbed to eventual finalists Alexander Peya and Bruno Soares in three sets. Next up for the pair was the Asian swing of tournaments, where they had their best run of results to date, making two finals in a row and competing in their first Masters 1000 tournament as partners. At the PTT Thailand Open, the pair were seeded third and went on to win their third title of the year. Peers and Murray defeated multiple Grand Slam champion and former world No. 1 Leander Paes on their way to the final, where they defeated Tomasz Bednarek and Johan Brunström in three sets. The following week, Peers and Murray reached their second final in a row, Peers' first ATP 500 final at the Rakuten Japan Open. Despite a close first set, the pair lost to established doubles pairing of Rohan Bopanna and Édouard Roger-Vasselin in straight sets.
Peers competed in his first ever Masters 1000 tournament at the Shanghai Masters, where he and Murray defeated established doubles champions Julien Benneteau, Nenad Zimonjić and Robert Lindstedt on their way to the semifinals, where they lost in straight sets to Spanish duo of Marrero and Verdasco, in a closely fought contest that ended up being decided by two tiebreakers.

### 2014

Peers began the year with regular doubles partner Jamie Murray at the Brisbane International. The pair made it to the semifinals, before losing to Daniel Nestor and Mariusz Fyrstenberg in straight sets. Their next tournament was the Heineken Open. They made the quarterfinals before withdrawing from the tournament. At the Australian Open they were the 15th seeds (the first time they were a seeded pair in a Grand Slam tournament). They made the second round before losing to Raven Klaasen and Eric Butorac in straight sets.
Peers played next at the 2014 ABN AMRO World Tennis Tournament with Julian Knowle while Jamie Murray was out with injury. The pair made it to the quarterfinals before losing to Julien Benneteau and Édouard Roger-Vasselin. Peers next played at the 2014 Open 13 with Jesse Huta Galung, but the pair lost in the first round. Peers next played at the 2014 Dubai Tennis Championships with previous partner Julian Knowle, but they lost in the first round.
Peers next played the Indian Wells Open with regular partner Jamie Murray but the pair lost in the first round to Benneteau and Roger-Vasselin. They next played at the Sony Open Tennis but lost in straight sets to sixth seeds Daniel Nestor and Nenad Zimonjić.
Peers and Murray started their clay court season at the Grand Prix Hassan II where they were seeded seconDlouhý]] and Tomasz Bednarek in straight sets. They made a second consecutive semi-final at the BRD Năstase Țiriac Trophy before losing to top seeds Jean-Julien Rojer and Horia Tecău.
At the BMW Open the pair defeated the top seeds Raven Klaasen and Eric Butorac in the semi-finals before defeating Colin Fleming and Ross Hutchins to win their first title of the year. They lost in the opening round of the Mutua Madrid Open, but managed to bounce back and reach the semi-finals of the Düsseldorf Open. They followed this up by reaching the third round of the French Open, which was both their best result at the tournament, where they were defeated by top seeds Bob and Mike Bryan.
They followed up the defeat by making the final of the Aegon Championships defeating the Bryan brothers in the second round but were beaten by second seeds Alexander Peya and Bruno Soares. They then lost their opening match of the Eastbourne International. At Wimbledon they were seeded 14th and made the third round before losing in five sets to Alexander Peya and Bruno Soares.
In August the pairing reached the final of the Winston-Salem Open as the third seeds but lost to the pairing of Cabal/Farah. In September, Murray/Peers also reached the final of the Malaysian Open as the second seeds but lost to fourth seeds Matkowski/Paes. The pair finished the year at the Swiss Indoors Open where they lost in the first round again to Matkowsi and Paes.

### 2015: Wimbledon & US Open finalist

Murray/Peers again began their year at the 2015 Brisbane International, where they defeated top seeds Rojer/Tecau in the first round before going on to win the title by defeating the pairing of Dolgopolov/Nishikori. The pair reached the third round at the 2015 Australian Open as the 16th seeds losing to 4th seeds Dodig/Melo. The pair's good form continued in Rotterdam, where after losing in the qualifying rounds they were handed a first-round match as lucky losers following a withdrawal. The pair went on to reach the final, before losing in a rematch against Rojer/Tecău.
In April, the pair reached their third final of the year in Barcelona, but lost to Draganja/Kontinen. In May, the pair reached back-to-back quarterfinals at ATP 1000 Masters in Madrid and Rome. In Madrid they lost to Lopez/Mirnyi, and in Rome they lost to eventual finalists Granollers/López.
In July, Murray/Peers reached the final of the 2015 Wimbledon Championships losing to Rojer/Tecău in straight sets.

### 2016: First World Tour Finals & Masters titles

The Olympic year brought changes to the doubles pairing. Also Peers chose a new partner, Henri Kontinen, to defend his title at the Brisbane International. The number 2 seeded pair reached the final beating the number 4 couple Inglot/Lindstedt, and went on to win the title by defeating Peers' compatriots Duckworth/Guccione. Peers and Kontinen separated for the next tournament in Sydney, and got beaten by the same opponents, the fourth seeds Bopanna/Mergea, in the second and the first round respectively. At the Australian Open Kontinen/Peers lost in the second round to Groth/Hewitt.
As a member of the Australian Davis Cup squad, Peers played a World Group 1st round rubber with Lleyton Hewitt against the American couple Bryan/Bryan. The Australian pair lost, letting the United States take a 2–1 lead in the tie. Eventually, Australia lost the tie, which meant that it would have to face the play-offs.
At the ABN AMRO World Tennis Tournament in Rotterdam, Kontinen/Peers managed to beat the second seeds Dodig/Melo before losing to Mahut/Pospisil in the semifinals. The pair stuck together even though they had a series of first round defeats, until reaching quarterfinals at the Monte-Carlo Masters. They were defeated by Cabal/Farah, despite a promising victory over the top seeds Rojer/Tecău in the second round. In Munich Kontinen/Peers fought their way into the final to encounter Cabal/Farah again. This time the outcome was reversed allowing Peers to celebrate his second ATP tournament title of the year with his Finnish companion.
At the Madrid Open Peers/Kontinen started well beating the second seeds Murray/Soares in the second round. In the quarterfinals the two had a new chance to beat Bopanna/Mergea, this time together, but they lost the match tie-break. In Rome they had to leave the tournament after another first round defeat. Also Roland Garros was a disappointment for the already consolidated pair, as they were sent home by Baker/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 Nestor/Qureshi. Neither these opponents could steal a set from the number two seeded pair, which thus obtained their third ATP title together.
Kontinen/Peers then headed to the American continent, reaching semifinals at the Citi Open and quarterfinals at Rogers Cup. Peers participated the Rio Olympics teaming with Chris Guccione. However, the pair lost their first match against the Argentine couple del Potro/González. In Cincinnati Peers tried to conquer the tournament with Kontinen, but they lost in the first round to Pouille/Tsonga. Their luck did not change by the time of US Open. After an initial victory over Delbonis/Pella, they were beaten in the second round by unseeded Lindstedt/Qureshi.
In September, Peers played again in the Davis Cup squad. With Sam Groth he defeated Martin/Zelenay of Slovakia, leading Australia to 3–0 victory that guaranteed a place in the following year's World Group.
At the Japan Open in Tokyo, Peers and Kontinen did not get past the first round, losing to Lindstedt/Peya. At the 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 BNP Paribas Masters event in Paris the duo made it all the way to the final without dropping a set where they again met Herbert and Mahut. This time they came out victorious in three sets to win their fourth title together and their first Masters title overall.
Peers/Kontinen qualified in 5th position for the World Tour Finals in London and was placed in the Fleming/McEnroe group with López/López, Klaasen/Ram and Herbert/Mahut. They progressed to the semi-finals after defeating each of their opponents in the group stage. In the semi-finals Kontinen/Peers faced off against Bob Bryan and Mike Bryan and came out with a 7–6, 6–4 victory to move on to the final against Klaasen and Ram. They emerged victorious yet again, winning 2–6, 6–1 [10–8] to claim their biggest tournament win to date. Peers ended the year at No. 9 on the Doubles Rankings, boosted by his success later in the year.

### 2017: Australian Open title, world No. 2 in doubles

Peers began the new year with his regular doubles partner Kontinen at Brisbane as the second seeds, however lost in the first round to Nishikori/Thiem in three sets. The duo then arrived at the Australian Open as the fourth seeds. They easily won their first- and second-round matches against González/Marrero and Baghdatis/Müller. Peers and Kontinen then faced Colombian pair Cabal and Farah and won in three gruelling tiebreakers to progress to the quarterfinals. There they faced the Australian duo of Sam Groth and Chris Guccione and won. In the semifinals, they faced another Australian pairing of Marc Polmans and Andrew Whittington. They progressed to their first Grand Slam final, where they won in straight sets against the Bryan brothers.

### 2021: First Olympic mixed doubles bronze medal for Australia, fourth Masters title

Peers represented Australia at the 2020 Summer Olympics in two events. In doubles, Peers partnered Max Purcell and lost in the first round. In mixed doubles, Peers partnered Ashleigh Barty, and they won bronze. Their bronze was Australia's first ever medal in an Olympic mixed doubles competition.
At the Indian Wells Open, he won his fourth Masters 1000 and 25th title overall partnering with new partner Slovak Filip Polášek, with whom he also reached the final of the San Diego Open earlier in the year.
