The 2021 World Series champion was designated for assignment by the Braves on Sunday, after a poor start to the season with just six hits in 31 at-bats.
Arcia batted .182 with six hits, a home run and two RBIs in 16 post-season games with the Braves since he was traded from the Milwaukee Brewers in 2021.
The 30-year-old has made 843 of his 920 appearances at shortstop, but will step in behind Ezequiel Tovar, who recently inked a $63.5 million, seven-year contract with the Rockies.
Colorado sits dead last in the majors at 9-45, after setting an MLB record for worst 50-game start through the modern era.
Arcia has slashed .241/.294/.373 with 87 homers and 335 RBIs over his 10-year career. His best season came in 2023 when he was named an all-star.
