Marcelo Mayer's trip to the IL means Boston might be in the market for a second baseman, while Connor Wong's struggles could lead to a new backup catcher.

After Mayer’s injury, the Red Sox recalled infielder David Hamilton, and though Hamilton will see some time at second, Rafaela’s offense has been too valuable to the lineup. Playing him at second and Duran in center makes the offense stronger. The moving parts have been a challenge for manager Alex Cora much of the season and even more so now.

In an interview with MLB Network Radio on SiriusXM, Breslow described the Red Sox’ deadline needs as “fluid” due to some of the recent individual performances they’ve had at certain positions.
