The Red Sox on Monday signed incumbent first baseman Mitch Moreland to a two-year deal, which means they're very likely moving on from their Eric Hosmer flirtation. That means signing slugger J.D. Martinez is likely priority No. 1 for Dave Dombrowski and company. Boston badly needs more power in the lineup, and that's why Martinez -- caveats and all -- makes a lot of sense for them.

The Sox, though, have a bit of a crowded roster, and absent a related move it's going to be hard to wedge Martinez into the lineup. For a while, the idea of trading Jackie Bradley Jr. has been bandied about, but Bradley of course projects as a useful member of the 2018 team. Since the Sox very much aim to contend next season, trading away a solid defensive center fielder who's going into his age-28 season and forecasts as a bounceback candidate at the plate may be self-defeating.

So keep Bradley and, assuming he's willing, install Martinez as DH? Sure thing, but the problem is that Hanley Ramirez is still around.
