Rosario's first stint in Atlanta came in 2021, when he was acquired from the Cleveland Guardians at the trade deadline and became a hero in October. During the 2021 NLCS, when the Braves beat the Los Angeles Dodgers in six games, Rosario batted .560 with three home runs and nine RBIs, including a three-run blast in Game 6.

As the Braves look to make a run to the World Series, Atlanta turned to a player who helped them win their last championship.

Rosario was acquired by the Braves at the 2021 trade deadline, the first time Acuna Jr. suffered a torn ACL. Rosario was one of the many outfielders the Braves acquired at that deadline — they also added Joc Pederson, Adam Duvall, and Jorge Soler — and he made one of the biggest impacts, especially come October.
