On Thursday night, the Red Sox found out along with everyone else that first baseman Josh Naylor was traded from the Arizona Diamondbacks to the Seattle Mariners. First base is a position the Red Sox have long hinted they could look to upgrade, and one of the few potential upgrades just went off the board.

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.

MassLive’s Fenway Insider Sean McAdam hosted a live mailbag Thursday and highlighted the upcoming MLB trade deadline. Throughout the mailbag, McAdam and MassLive reporter Lauren Campbell discussed the Boston Red Sox ’ plans, whether trading Jarren Duran makes sense and more.

"We’re approaching the deadline looking for ways to bolster the team given the play over the last month-and-a-half or so.” The post Craig Breslow calls Red Sox’ trade deadline needs ‘fluid,’ plans to ‘bolster’ roster appeared first on Boston.
