Olli Määttä Bio
Olli Määttä is a Finnish professional ice hockey player who plays as a defenceman for the Utah Mammoth of the National Hockey League (NHL). Born on 22 August 1994 in Jyväskylä, Finland, he was selected 22nd overall by the Pittsburgh Penguins in the first round of the 2012 NHL Entry Draft. Known for his shot-blocking ability and hockey intelligence, Määttä has built a reputation as a steady, defence-first blueliner across more than a decade of professional play.
Over his career, Määttä has also represented the Pittsburgh Penguins, Chicago Blackhawks, Los Angeles Kings, and Detroit Red Wings, capturing a Stanley Cup championship with Pittsburgh in 2016. He has worn Finland’s colours at the Winter Olympics, the World Junior Championships, and the senior World Championship, establishing himself as one of his country’s trusted defenders on the international stage.
Early Life and Background
Olli Määttä was born on 22 August 1994 in Jyväskylä, a city in central Finland long associated with winter sports and grassroots hockey. He grew up in a sporting household with two older brothers, Antti and Eero, and his early childhood revolved around outdoor rinks and local youth programmes. Määttä began playing organized hockey in 2000, after he complained to his parents that all the other children were allowed to play the sport.
That early encouragement from his family sparked a steady climb through Finland’s junior system. Määttä joined the under-16 programme of his hometown club JYP, where his size and composure quickly set him apart from peers his age. Within two seasons, his play had earned him call-ups to JYP’s under-18 and under-20 squads, as well as a place on Finland’s national under-16 team, where he posted 13 points in 13 games.
Path to Hockey
Määttä’s rise through the Finnish junior ranks was rapid and well documented. As a 16-year-old he split time between JYP’s under-20 team and the club’s D Team in the Mestis, Finland’s second-tier professional league, while also representing Finland at both the under-18 and under-20 levels. At the 2011 IIHF World U18 Championships he led all Finnish defencemen in scoring with four points, and shortly afterwards he became the youngest player ever to suit up for Finland at the World Junior Championships, a record later surpassed by Aleksander Barkov.
That same summer, Määttä was selected 85th overall by SKA Saint Petersburg in the 2011 KHL Draft before being chosen first overall by the London Knights in the 2011 CHL Import Draft. He accepted London’s invitation and crossed the Atlantic to begin his Ontario Hockey League career in the autumn of 2011, joining a Knights team built to contend for the J. Ross Robertson Cup.
Olli Määttä Career
OHL Career with the London Knights (2011–2013)
In his first OHL season, Määttä quickly became a key part of London’s defence corps, pacing the team in defensive scoring with 32 points in 58 games despite missing six games for the 2012 World Junior Championships. A concussion suffered in the tournament opener against Canada forced him out of that event, but he returned to lead the Knights through the OHL playoffs, finishing tied for the team scoring lead with 23 points in 19 post-season games as London captured the J. Ross Robertson Cup.
The Knights’ playoff run carried them to the 2012 Memorial Cup in Shawinigan, Quebec, where London fell just short in the championship game against the host Cataractes. Määttä returned for a second OHL season in 2012–13, helping the Knights post a 50–13–2–3 record and capture another league title with a 3–2 victory over the Barrie Colts in seven games. A 2013 Memorial Cup appearance ended earlier than hoped, but his two-year body of work cemented him as one of the OHL’s top defencemen.
Pittsburgh Penguins (2013–2019)
Määttä made the Pittsburgh Penguins’ roster out of training camp in 2013, aided by an injury to Kris Letang, and recorded his first NHL points on 8 October 2013 with two assists in a win over the Carolina Hurricanes. He scored his first NHL goal on 19 October against Roberto Luongo and the Vancouver Canucks, then settled into a third-pairing role before injuries to Rob Scuderi and Paul Martin pushed his ice time above 21 minutes per game. By December 2013 he was producing like a top-four defenceman, helping Pittsburgh post a 10–2 run.
His first full NHL season ended with a brief stint on the sideline after an upper-body injury, and in October 2014 Määttä underwent surgery to remove a tumour from his neck that doctors feared could be a low-grade thyroid cancer. He returned within two weeks, then missed the remainder of 2014–15 after a second shoulder surgery. Määttä rebounded the following year to help Pittsburgh win the Stanley Cup in 2016, and later played his 300th career NHL game on 1 April 2018, finishing that season with 29 points in 82 games.
Chicago Blackhawks (2019–2020)
On 15 June 2019, Määttä was traded to the Chicago Blackhawks in exchange for Dominik Kahun and a 2019 fifth-round draft pick, joining a retooling blue line that needed steady two-way play. In 2019–20 he tallied four goals and 17 points in 65 games while averaging 18:25 in ice time. During Chicago’s playoff run, he led the team with a plus-seven rating and paced Blackhawks defencemen in scoring with three goals and six points in nine games.
Los Angeles Kings (2020–2022)
Määttä was traded to the Los Angeles Kings on 4 October 2020 in exchange for Brad Morrison, joining a young Kings team in transition. He provided veteran stability on the back end through two seasons in California, contributing reliable defensive play and penalty killing as Los Angeles pushed toward a return to playoff contention.
Detroit Red Wings (2022–2024)
On 13 July 2022, Määttä signed a one-year, $2.25 million contract with the Detroit Red Wings as a free agent, and on 16 February 2023 he inked a two-year, $6 million extension to remain in Detroit. He served as a steady third-pairing presence for the rebuilding Red Wings, helping mentor younger defencemen while logging consistent minutes in all situations.
Utah Mammoth Era (2024–Present)
With the Utah Hockey Club facing a depleted blue line through injury to open their inaugural season, Määttä was traded from the Red Wings to Utah on 29 October 2024 in exchange for a third-round pick in 2025. The move reunited him with an expansion franchise eager for experienced leadership on the back end. He immediately slotted into a top-four role, providing shot-blocking, penalty killing, and a calming veteran presence for a young roster.
Driving Style and Strengths
Määttä’s game is built on positional defence, intelligent reads, and an elite ability to block shots. He thrives in tight-checking, defensive-zone situations and has long drawn praise for his hockey IQ and composure under pressure.

Notable Events and Milestones
