Robert Thomas

Prior to the 2019–20 season, Thomas underwent surgery to repair a tendon in his left wrist. He was eventually medically cleared to play and was once again named to the Blues' opening night roster. Leading up to opening night, Thomas was expected to have a breakout season and a "Smooth sophomore season" in the top six. Although the NHL suspended play due to COVID-19, Thomas placed fifth on the team in goals per game and first with primary assists. During the pause in play, Thomas captained a league wide Fortnite tournament for charity with teammates Vince Dunn and Jordan Kyrou. Together, they finished in second place and donated $50,000 to the St. Louis Children's Hospital, $25,000 to the St. Louis Area Foodbank, and $25,000 to muscular dystrophy research.

Upon the conclusion of the 2018 Memorial Cup Semifinal game, Thomas revealed he suffered an ankle injury during the Bulldogs series against the Sault Ste. Marie Greyhounds. As a result, Thomas was unable to attend the Blues' development camp, but was medically cleared to play during the Blues' Rookie Camp on September 5, 2018. Thomas eventually made the Blues' opening night roster for the 2018–19 season, and subsequently made his NHL debut on October 4 against the Winnipeg Jets. However, during the following six games, Thomas was a healthy scratch in the Blues' lineup for two of them. Working his way back into the lineup, Thomas recorded his first NHL point on October 12 in a 5–3 win over the Calgary Flames, and his first NHL goal on November 21 in a 4–1 loss to the Nashville Predators. Thomas remained on the team's roster for the entirety of the season and finished with 33 points in 70 games as the Blues qualified for the 2019 Stanley Cup playoffs.

A native of Aurora, Ontario, Thomas played Bantam and AAA ice hockey with the York Simcoe Express before beginning his major junior ice hockey career in the Ontario Hockey League (OHL). He spent three seasons in the OHL with the London Knights and Hamilton Bulldogs. While with the Knights, Thomas won the 2016 Memorial Cup as a rookie and was drafted in the first round, 20th overall, by the Blues in the 2017 NHL Entry Draft. He made his NHL debut on October 4, 2017, against the Winnipeg Jets and recorded his first career NHL goal a month later. As the youngest player on the Blues' roster, Thomas won the Stanley Cup in 2019.

Following an impressive training camp and pre-season with the Blues, Thomas was signed to a three-year, entry-level contract on September 28, 2017, before he was returned to continue his development with the London Knights for the 2017–18 season. As the Knights were waiting on key players to return from their respective NHL clubs, the Knights began the season with a rocky start and a 1-4-0 record. On November 3, 2017, Thomas was named captain of the Knights, alongside alternate captains Sam Miletic, Max Jones, Cliff Pu, and Evan Bouchard. Shortly thereafter, he recorded the game winning goal to clinch coach Dale Hunter his 700th regular season win. His run as captain was shortlived, however, as on January 8, 2018, Thomas was traded to the Hamilton Bulldogs in exchange for Connor McMichael and five draft picks. While with the Bulldogs, Thomas was suspended five games for slashing Peterborough Petes forward Zach Gallant in the mouth, though he still finished the regular season tied for 20th around the league in scoring. He continued his scoring success during the 2018 OHL Playoffs and recorded 32 points in 21 games to help the team clinch the J. Ross Robertson Cup. As a result of his success, Thomas was awarded the Wayne Gretzky 99 Award as MVP of the playoffs.

On June 20, 2017, Thomas was selected to attend the Canada men's national junior ice hockey team U20 Team Summer Development Camp prior to the 2018 World Junior Ice Hockey Championships. Playing alongside fellow Blues prospect Jordan Kyrou, Thomas helped Canada clinch a gold medal after a 3-1 win against the Sweden men's national junior ice hockey team.

Thomas developed into a more offensive role with the Knights during the 2016–17 season and recorded a career high 66 points in 66 games. As a result, he was named to the 2017 CHL/NHL Top Prospects Game alongside teammate Alex Formenton and was the recipient of the OHL's Most Sportsmanlike Player of the Year Award. His offensive play also earned him a boost in ranking from 28th to 22nd amongst North American skaters by the NHL Central Scouting Bureau. Thomas shared his surprise at his jump in ranking by saying, "I actually was expecting, from talking to people, to go in the third round...I was talking to a lot of (U.S. schools) at the time, and when I jumped to the second, I was pretty shocked." He was eventually chosen in the first round, 20th overall, by the St. Louis Blues and invited to their rookie camp over the summer.

Internationally, Thomas has competed for the Canadian national junior team in various tournaments since 2015. He won a gold medal for his home country during the 2015 World U-17 Hockey Challenge and 2018 World Junior Ice Hockey Championships.

Thomas was selected by the London Knights of the OHL in the second round, 26th overall, in the 2015 Ontario Hockey League (OHL) Priority Selection. Knights coach Dale Hunter praised Thomas for his "vision, speed, hockey sense and ability to pass the puck" and considered him a replacement for former Knight Bo Horvat. In his rookie season with the Knights, Thomas recorded 15 points in 40 games as they qualified for the 2016 OHL Playoffs. He played with the team as they reached the J. Ross Robertson Cup and won the 2016 Memorial Cup. Thomas played his rookie season as a defensive forward, which he developed into a more offensive role prior to his sophomore season.

As a citizen of Canada, Thomas has competed for the Canadian national junior team in various tournaments since 2015. During his rookie season with the London Knights, Thomas was released by the team to allow him to compete with the Canadian national junior team at the 2015 World U-17 Hockey Challenge. He played in six games and recorded one point for Team Canda White as they clinched a gold medal.

Growing up in Aurora, Thomas played Bantam and AAA ice hockey with the York Simcoe Express of the Eastern AAA Minor Midget Hockey League. During the 2014–15 season, Thomas recorded 45 points in 34 games for the Express. As he grew out of Bantam hockey, Thomas played for the St. Andrew's College Saints under–16 team for two years while also attending the private school. His younger brother would also attend and graduate from the school in 2019.

Robert Thomas (born July 2, 1999) is a Canadian professional ice hockey centre currently playing for the St. Louis Blues in the National Hockey League (NHL).

Thomas was born on July 2, 1999, in Aurora, Ontario. His father Scott, a chef by trade, trained Thomas for the first five years of his hockey career. His grandfather Bruce Waechter also helped by building a backyard rink for him to train on out of plywood.

At the age of 19, Thomas helped the Blues advance to their first conference final since 1996 by assisting on both goals during Game 7 of the Western Conference Second Round. Afterwards, former Blues player Keith Tkachuk said, "For someone that young, to clearly stand out in a Game 7 from start to finish, was one of the best performances you have ever seen in the National Hockey League, in my opinion." As the youngest player competing during the Western Conference Final against the San Jose Sharks, he suffered a wrist injury during Game 6 as the Blues beat the Sharks. He returned to the lineup for Game 1 of the 2019 Stanley Cup Finals against the Boston Bruins, but suffered another injury and was out of the lineup until Game 6. His efforts during the postseason helped the Blues win their first Stanley Cup in franchise history. Upon winning the Cup, Thomas' hometown of Aurora added a sign underneath their city's welcome sign stating "Home of Robert Thomas, Stanley Cup champion."
