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.

The Boston Red Sox need to acquire controllable starting pitching at the trade deadline. A deal with the Pittsburgh Pirates could give them that.

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.
