In the postseason, Morgan showcased his skills by allowing only two hits over four innings in six games against the Detroit Tigers and New York Yankees.

The Cleveland Guardians traded right-hander Eli Morgan to the Chicago Cubs on November 20, 2024, in exchange for minor league outfielder Alfonsin Rosario.

In the trade, the Cubs designated infielder Patrick Wisdom for assignment, marking a significant roster shift.

Morgan, 28, had a successful 2024 season, recording a 3-0 record with a 1.93 ERA in 32 appearances, contributing to the Guardians' status as having the best bullpen in MLB.

Alfonsin Rosario, the player acquired by the Guardians, is a 20-year-old outfielder who played for Single-A Myrtle Beach last season, where he batted .230 with 16 home runs and 73 RBIs.

Rosario also demonstrated speed, stealing 20 bases and scoring 61 runs, and was drafted by the Cubs in the sixth round of the 2023 MLB Draft.

His performance improved after recovering from shoulder and elbow injuries, and he gained the trust of manager Stephen Vogt, highlighted by a streak of 16 consecutive scoreless innings from late August to late September.

Wisdom had spent five seasons with the Cubs, consistently hitting over 20 home runs from 2021 to 2023, but his playing time decreased as the team integrated third baseman Christopher Morel.

Overall, Morgan's career with the Guardians spanned four seasons, during which he compiled an 18-12 record and a 3.97 ERA in 161 games.

Patrick Wisdom, 33, had a disappointing 2024 season with a batting average of .171, hitting eight home runs in 75 games, which contributed to the Cubs' decision to move him.

Morgan's addition to the Cubs is expected to strengthen their bullpen, which struggled in the previous season, potentially positioning him for middle relief and save opportunities.

Morgan features a three-pitch arsenal, including a fastball, slider, and changeup, with opponents hitting just .176 against his fastball last season.
