Long could be called up to the Marlins before the end of the season to fill a short-side platoon role in left field and at first base, Christina De Nicola of MLB.com reports.

Acquired from the Cubs at the trade deadline in the Braxton Garrett deal, Long has had an up-and-down 2026 season at Triple-A, but since the beginning of July he boasts a .337/.425/.606 slash line with 13 doubles and five homers in 120 plate appearances. The 24-year-old could provide some balance to a heavily left-handed Miami lineup, but he would likely have a hard time winning consistent playing time.

The Cubs traded Long and Jace Beck to the Marlins on Monday in exchange for Braxton Garrett, Francys Romero of BeisbolFR.com reports.

Long had been blocked at Triple-A while in the Cubs organization for the past couple years, but he is also having a worse season this year (108 wRC+) at Triple-A than he did last year (131 wRC+). A righty-hitting first baseman and left fielder, Long is slashing .283/.364/.455 with 12 home runs and a 21.2 percent strikeout rate in 99 games as a 24-year-old.

After facing live pitchers in a side session Friday, Long returned to game action a day later for the first time since late February. The 24-year-old sprained his elbow attempting to reach for a wide throw to first base, but he sustained no structural damage, and he now looks fully good to go after a few weeks of rehab work. Long is expected to begin the regular season with Triple-A Iowa and give the Cubs some depth behind Michael Busch.

Long has resumed regular workouts and facing live pitching is another step forward in his rehab process from an injury he sustained in an exhibition game last month. The 24-year-old was diagnosed with a left elbow bruise and cleared of any structural issues earlier in March, so he should be fully healthy in the near future. Long figures to being the season with Triple-A Iowa and could push toward the majors at some point if he continues to tear up the level like he did in 2025.

Long has been diagnosed with a bruise and cleared of any structural issues with his left elbow, putting him on track to potentially return to baseball activities by the end of the week, Bruce Levine of 670TheScore.com reports.

The 24-year-old was unable to join Team Chinese Taipei for the World Baseball Classic due to the injury, but he's now progressing toward game action. If he can avoid any setbacks, Long could be ready to join Triple-A Iowa for the start of the minor-league season.
