Cubs acquire left-hander Braxton Garrett from Marlins in unconfirmed trade, per MLB.com report

The Cubs are reportedly adding left-hander Braxton Garrett from the Miami Marlins, according to a report from. The deal, described as an exchange between the organizations, would send minor league first baseman/outfielder Jonathon Long and right-hander Jace Beck to the Marlins. At the time of publication, reported that the teams had not confirmed the trade, making it best viewed as a near-term development rather than a fully finalized transaction.

For the Cubs, the motivation is straightforward. They are targeting pitching depth in a left-handed arm, a profile that can be difficult to develop quickly within a single season. Garrett’s value in the reported package is amplified by what MLB Pipeline ranks him as inside the Cubs’ larger prospect picture. In the same report, Long is described as the Cubs’ No. 10 prospect, while Beck is ranked No. 28 on the team’s list, indicating Miami would be receiving players viewed as meaningful pieces of Chicago’s farm system.

The prospect context matters because trades at this point in the season typically reflect a balancing act. Clubs that are aiming to contend often prioritize immediate major-league fit, while rebuilding teams or teams positioned differently in the standings look for controllable, long-horizon talent. With Long and Beck both cited via Chicago’s internal prospect rankings, the reported framework suggests Miami would be buying into the future potential of multiple profiles rather than targeting a single slot.

Braxton Garrett, the player the Cubs would receive, is the element around which the trade construction appears to revolve. Garrett being identified as a left-hander matters for roster construction because left-handed pitching can shape bullpen usage and matchup planning. Even without a detailed stat line in the report, the Cubs’ willingness to package two prospects they rank as top-30 underscores that they are trying to improve the quality and flexibility of their pitching pipeline in the short term.

Still, the transaction’s status is incomplete. ’s report specifically noted that the teams had not confirmed the trade. Until both organizations issue their standard transaction communication, additional reporting could refine the final players involved, or the clubs could decide to hold the deal if negotiations change.

What to watch next is whether official announcements follow and how the Cubs intend to deploy Garrett once he is cleared for the organization. If Chicago confirms the trade, the immediate attention will likely shift to how Garrett fits into the Cubs’ pitching calendar and who, among their existing minor league options, he would challenge for opportunities. On the Marlins side, Long and Beck represent the kind of prospect haul that could accelerate roster planning, particularly if Miami chooses to develop them along a timetable aligned with their broader organizational goals.

In the meantime, this report reflects a common deadline-day dynamic: prospect rankings become leverage, and teams convert internal evaluations into external assets. The Cubs appear to be using Long and Beck, ranked No. 10 and No. 28 respectively in their pipeline, to acquire a left-handed arm they believe can help the organization. With confirmation pending, fans should treat the report as an actionable but not final chapter in the Cubs’ season-building process.
