Carpenter was drafted by the
Detroit Tigers in the 19th round, with the 562nd overall selection, of the
2019 Major League Baseball draft. Carpenter signed with the Tigers and split his first professional season between the rookie–level
Gulf Coast League Tigers and Low–A
Connecticut Tigers, batting .303 with nine home runs and 35 runs batted in over 47 games. He did not play in a game in 2020 due to the cancellation of the minor league season because of the
COVID-19 pandemic. Carpenter spent 2021 with the Double–A
Erie SeaWolves and hit .262 with 15 home runs, 74 runs batted in, and 24 doubles over 112 games. He returned to Erie to open the 2022 season. He was named
Eastern League Player of the Month for May. After batting .304 with 22 home runs and 48 runs batted in during 63 games with Erie, he was promoted to the Triple–A
Toledo Mud Hens in late June. On August 10, 2022, the Tigers selected Carpenter's contract and added him to the Major League roster. He made his MLB debut the same day as Detroit's starting
designated hitter, going hitless over four
at-bats. He collected his first MLB hit on August 14, a single versus the
Chicago White Sox. Carpenter hit his first MLB home run on August 15 off of
Eli Morgan of the
Cleveland Guardians. For the 2023 season, Carpenter played in 118 games, batting .278 with 20 home runs and 64 runs batted in. Carpenter began the 2024 campaign with Detroit, hitting .283 with eight home runs and 29 runs batted in across 50 games. He was placed on the injured list with

Seattle Mariners. In the regular season, Carpenter hit .284 with 18 home runs and 57 runs batted in across 87 games. On October 7, in Game 2 of the
2024 American League Division Series against the
Cleveland Guardians, Carpenter hit a three-run home run with two outs in the top of the ninth inning off of Cleveland closer
Emmanuel Clase, who had given up only 2 home runs in 74.1 innings, breaking a 0–0 tie and leading to a 3–0 Tigers win. He finished the 2024 postseason batting .306 with four home runs and 10 runs batted in for eight games. On June 2, 2025, Carpenter hit three home runs in a 13–1 Tigers victory over the
Chicago White Sox. It was the first three-homer game of his career, and the first by a Tiger since
Victor Martínez in 2016. Carpenter was placed on the 10-day injured list with a hamstring injury on July 2, 2025. For the 2025 season, Carpenter hit .252 with 26 home runs and 62 RBI. In the
2025 ALDS, Carpenter hit a 2-run
homer against the Mariners in Game 1 to put the Tigers in the lead, which ultimately was crucial in their 3-2 win in 11 innings. In Game 5, he homered again and reached base six times, tying a postseason record shared with
Kenny Lofton and
Stan Hack, though the Tigers lost in 15 innings. The record was ultimately broken by
Shohei Ohtani during the
2025 World Series. On January 6, 2026, the Tigers and Carpenter agreed on a one-year, $3.275 million contract, avoiding arbitration.
