Cyr enrolled at Miami on June 3, 2024.[6] In his freshman campaign, he played in 60 of the team's 63 games. Primarily as a second baseman, he slashed .305/.427/.620 to earn Freshman All-ACC and Freshman All-American honors.[7] During a home elimination game against Louisiana in the 2023 NCAA Division I Baseball Tournament, Cyr hit a three-run home run in a game that the Hurricanes eventually won 8–5.[8] They were eventually eliminated against Texas in a game where he went 1-for-4 and scored a run.[9]
Ahead of his sophomore season, Cyr was projected to be the 20th best 2025 MLB draft prospect in college baseball.[10] Instead of starting the season at second base, he would start at left field. He earned ACC Player of the Week honors after going 8-for-16 with 3 home runs and 11 RBI in a 4-game stretch. One of the home runs was a go-ahead grand slam to complete Miami's largest comeback win since 1992.[11][12] Cyr suffered a season-ending thumb injury on April 5 while sliding into a base against Duke.[13] He ended the season with only 25 games, having slashed .284/.397/.537.[14]
Cyr entered the transfer portal and committed to Florida on June 4, 2024.[15]
Considered one of the top 12 transfers in college baseball by NCAA.com, Cyr would be the opening day starter at left field for Florida.[16] He reached base for 21 straight games to open the season, slashing .373/.469/.612 during that time.[17] An injury crisis late in the season meant that he also saw very limited action as a second baseman.[18] During the 2025 NCAA Division I Baseball Tournament, Cyr went 5-for-13 as the Gators were eliminated by Eastern Carolina.[19]
