Windsor Spitfires for deliberately injuring an opposing player, Wedgewood made his first career playoff start for the Whalers, making 70 saves in a 3–2 loss in overtime, which later became known as the "Wedgewood Game". His tremendous performance attracted the attention of NHL scouts, and Wedgewood was drafted 84th overall in the third round by the
New Jersey Devils in the
2010 NHL entry draft. During his fourth and final year of major junior hockey in the
2011–12 season with the Whalers, Wedgewood was signed by the Devils to a three-year, entry-level contract on March 20, 2012.

2015–16 season, on March 20, 2016, he won his
NHL debut for the Devils against the

Colorado Avalanche that ended their 18-game home win streak, on February 1, 2022.
Dallas Stars On March 20, 2022, Wedgewood was traded by Arizona to the
Dallas Stars in exchange for a conditional
2023 fourth-round draft pick. Acquired by the Dallas Stars as they sought depth in goal during a push for the playoffs, and with injuries to their primary goaltender,

Early in the campaign, Wedgewood was thrust into the starting role after an injury sidelined Oettinger in December 2023.

Elias Pettersson of the
Vancouver Canucks that immediately led to a game-winning goal by

His stats, reflected his resilience under increased pressure and he completed the season having made a career high 32 appearances, and notching 16 wins.

Providing instant stability to the Avalanche's goaltending, Wedgewood posted his seventh career shutout and first in an Avalanche jersey with a 4–0 victory over his original club, the New Jersey Devils, on December 8, 2024. After leading the NHL in wins through the early
2025–26 season, posting a 10–1–2 record, he signed a one-year contract with the Avalanche on November 13, 2025, to stay with the team through the 2026–27 season. He recorded his first career assist on a goal by
Brock Nelson during a game against the
New York Rangers in November 20. Following a shutout at the
Seattle Kraken on April 16 to conclude the season, Wedgewood and teammate
Mackenzie Blackwood won the
William M. Jennings Trophy after giving up the fewest goals against, at 197. The last member of the Avalanche to win the trophy was
Patrick Roy in the
2001–02 NHL season. Wedgewood led the league in goals against average (2.02) and save percentage (.921), becoming the first Avalanche goaltender to finish the season as the league leader in both categories. He also finished tied for 4th in wins (31) and tied for 3rd in shutouts (4) among all goaltenders. He started and won his first playoff game on April 19, 2026, during game one of the Avalanche's first round match-up against the
Los Angeles Kings. During game two of the Avalanche's series against the
Los Angeles Kings during the
2026 Stanley Cup playoffs, Wedgewood saved a penalty shot by
Quinton Byfield; he became the second goalie in franchise history to make a save on a penalty shot during the playoffs, after
Philipp Grubauer. Wedgewood's performance during the series, which didn't see many goals scored by either team and also saw an impressive performance by Kings goalie
Anton Forsberg, was widely cited as one of the best of the best on the ice. The Avalanche swept the Kings and Wedgewood became the first Avalanche goalie to earn a complete sweep in his first postseason series. ==International play==
