The
Colorado Rockies drafted Doyle in the fourth round, with the 129th overall selection of the
2019 Major League Baseball draft. He received a $500,000 signing bonus. Doyle was assigned to the
Grand Junction Rockies of the
Pioneer League, where he led the league with a .383 batting average with 8 home runs, 33 RBI, and 17 stolen bases. He let the league in batting average and
on-base percentage. He did not play in a game in 2020 due to the cancellation of the minor league season because of the
COVID-19 pandemic and spent most of the year training in
Manassas, Virginia at a baseball complex alongside local college players until taking part in the Rockies' fall instructional league. Doyle was named the best overall athlete in the Rockies' minor league system going into the 2021 season by
MLB.com. He was assigned to the
Spokane Indians of the
High-A West League for 2021, where he batted .279 with 16 home runs, 47 RBIs, and 21 stolen bases in 97 games played and won a Minor League Gold Glove Award. Doyle played most of the 2022 season for the Double-A
Hartford Yard Goats, appearing in nine games for the Triple-A
Albuquerque Isotopes in September. In 132 games, he hit a combined .256/.300/.473
slash line with 26 home runs, 77 RBI, and 23 stolen bases. On November 15, the Rockies added Doyle to their
40-man roster to protect him from the
Rule 5 draft. Doyle was optioned to Triple-A Albuquerque to begin the 2023 season. On April 24, Doyle was promoted to the major leagues for the first time. He had hit .306/.404/.633 with 5 home runs and 8 RBIs in 12 Triple-A games prior to his promotion. Doyle made his major league debut later that day, starting in center field and going hitless in three at-bats with one walk and one run scored. On September 2, Doyle made a throw from center field with a speed of 105.7 mph, the fastest throw by a position player since at least 2015, according to
Statcast. Doyle ended his rookie season hitting .203 with 10 home runs and 22 stolen bases in 126 games while winning a
Gold Glove Award in center field. In 2024, Doyle won his second consecutive Gold Glove. He had an 11.4 ultimate zone rating (UZR), the highest among all MLB center fielders and second-best among all MLB players. He was worth 16 Outs Above Average (OAA) and had 14
Defensive Runs Saved (DRS). In addition, he won the
Fielding Bible Award for center field. He became the first Rockies player to win back-to-back Gold Glove Awards since
Nolan Arenado did so in 2019 and 2020. For the season, Doyle
hit .260/.317/.446 with 23 home runs and 30 stolen bases in 149 games. In April 2025, Doyle went on the
bereavement list, missing seven days after his wife suffered a miscarriage. He later said he may have returned to the team too soon. He also worked to improve his swing, missing several games in May. == Personal life ==
