The Boston Red Sox trading Jarren Duran seems unlikely, but if they do, they might have to get creative to get back what they need.

The Boston Red Sox are reportedly interested in adding Pittsburgh Pirates starting pitcher Mitch Keller, although they have competition from other teams, per Noah Hiles of the Pittsburgh Post-Gazette.

With Duran, Roman Anthony, Ceddanne Rafaela, Wilyer Abreu, Rob Refsnyder, and Masataka Yoshida, the Red Sox have a surplus of major league outfielders, but that logjam has been temporarily alleviated by Rafaela’s move to the infield following an injury to Marcelo Mayer.
