Joe made his major-league debut in 2019 as a member of the San Francisco Giants. The Giants previously acquired him in a trade with the Cincinnati Reds after the Reds landed him from the Dodgers in the 2018 Rule 5 Draft. Joe subsequently rejoined the Dodgers organization because he didn't finish the season in San Francisco.
Following his return, the 27-year-old hit .300/.426/.503 with 15 home runs and 68 RBIs in 105 games for the Oklahoma City Dodgers, Los Angeles' Triple-A affiliate in the Pacific Coast League.
