The Red Sox may need a meaningful infield upgrade, as their depth remains a concern entering the season despite adding Caleb Durbin and Isiah Kiner-Falefa. Durbin has struggled early, Trevor Story has not produced at expected levels, and Marcelo Mayer has spent time at second base but may not be ready for everyday at-bats.

A recent SI.com mock trade from Ethen Hutton envisions a bold move: Boston would acquire Ketel Marte from the Arizona Diamondbacks in exchange for a package centered on pitcher Brayan Bello along with prospects Connelly Early and Justin Gonzalez. Marte, a six-year, $105 million contract player, would address the infield and offense gaps for the Red Sox.

Hutton argues the deal could benefit both teams by filling Arizona’s bullpen depth needs while giving Boston a proven All-Star infielder to stabilize the lineup. The proposed trade would see Bello as the centerpiece sending value from Boston to Arizona, with Early and Gonzalez adding future upside.

However, the trade faces real-world hurdles. Arizona would likely resist moving Marte unless they falter significantly this season, given the Diamondbacks’ competitive window. The Red Sox would have to weigh Bello’s current performance—an ERA over 6.00 through three starts—against Marte’s impact.

If the Diamondbacks stay firm, Boston could still pursue infield help elsewhere, but Marte’s availability appears unlikely in the near term. The proposed package underscores the Red Sox’s obvious need for a reliable, everyday option in the infield and the high value teams place on established performers.

Bottom line: while a Marte-for-Bello type deal would solve several roster questions for Boston, it hinges on Arizona’s willingness to part with a core infielder and on Boston overcoming questions about Bello’s early-season form.
