If the Sox make moves for starting pitching, leaving Houck as no Whitlock in the bullpen makes even more sense. Whitlock already is the 2 inning lockdown reliever. Houck is probably the best replacement for Barnes we’ll find.
Sale, Pivetta, Eovaldi and Seabold make for an acceptable start to the rotation. Throwing Whitlock into the mix in the rotation is just as questionable as Seabold, and also creates the very opening in the bullpen you say they need. Plus a bullpen with Houck, Barnes, Taylor, Whitlock, and Darwinzon is a really good start. Feltman and Valdez might be in the mix as well.
And if Robles works out, he might be back…
