Lowrey is done for the year. He may be back on the field but no sane person should expect any more offensive production form him than what he has shown to date. I hope he can strengthen his wrist during the off season and come to spring training ready to play.
Gonzalez is a stopgap measure. He is clearly better than Woodward and offers no upgrade over Green offensively. He is here to add depth at middle infield. The Sox are going backwards, and have been since before the all star break. Gonzalez will have little bearing on how the season plays out, nor would any of the likely alternatives.
Taken in that context, I'm ok with the move.
