This was a straight up salary dump. If Dombrowski wanted a legitimate prospect, he could have gotten more by paying part or all of Clay's salary.
If the goal was to get below the limit, it makes sense. But it does come at the cost of pitching depth and moves Owens and Johnson one rung further up the ladder. Hopefully some pitching with options better thsn those two can be acquired.
Doubtful the Sox chase Encarnacion, as they appear to be set on staying under. Maybe if Bautista is willing to accept a Nelson Cruz type deal (1yr $8mill) that might happen, but probably not. Although if a one year $1mill player option was added, he would only count as $4.5mill towards the Luxury Tax.
There are still a few out of options relievers fighting for maybe 2 spots in the bullpen - Hembree, Ross, Elias, and Abad. I would expect a deal or two here that can hopefully restore some pitching depth. ...
