Mark Alexander Terrance Pysyk[1] (/ˈpɛsɪk/ PESS-ik; born January 11, 1992) is a Canadian professional ice hockey player who currently plays for SaiPa in the Finnish Liiga.

[3] He began the season with the AMBHL but was told by Oil Kings head coach Steve Pleau he would make his WHL debut after the Christmas break.

[5] In his second game since being called up from Midget AAA, Pysyk was working with the power play unit and recorded his first WHL assist.

His efforts were recognized by Oil Kings GM Bob Green, who said: "He carried our team on his back a lot of nights this winter, and the fact that he played on a broken foot for a couple of games before he was forced to end his season early shows how much character he's developed.

[11] Following his draft, Sabres' director of amateur scouting proposed Pysyk would need three years before making his NHL debut due to his small stature and light weight.

[12] After being returned to his junior team by the Sabres after training camp, Pysyk was named the captain of the Oil Kings on September 28, 2010.

[13] On May 13, 2012, Pysyk, along with the rest of the Edmonton Oil Kings, won game 7 of the WHL Finals, against the Portland Winter Hawks with a score of 4–1, to win the Ed Chynoweth Cup.

[16] Again in the 2015–16 season, Pysyk had trouble establishing himself at the NHL level, suffering a lower body injury that sidelined him for 22 games.

[22] Leaving the Stars after one season, Pysyk returned to his original club, the Buffalo Sabres, agreeing to a one-year, $900,000 contract on July 28, 2021.

[23] Shortly after he was acquired by the Red Wings, the club announced that he would miss the beginning of the 2022–23 season after he suffered an Achilles tendon tear and underwent surgery with a recovery timetable of four to six months.

[25] Pysyk left the Red Wings at the completion of his contract and was later signed as a free agent to a professional tryout deal (PTO) with the Pittsburgh Penguins on August 30, 2023.

[29] As a free agent from the Flames, Pysyk for the second consecutive year went un-signed over the off-season before he accepted an invitation to attend the Anaheim Ducks training camp for the 2024–25 season on a professional tryout on September 12, 2024.
