I say keep him the rest of the year, let's keep the club together and let this play out. the club house seem happy with all the manny stuff behind them. also he might not play all 3 pos well but atleast they are not just throwing someone from AAA or AA out there like the Stinkees.
If Millar goes the media will bring this to the club everyday... I can hear it now "What impact will it have on the team now that Millar is gone", so IMO keep him.
P.S. poor Pedro lose no hitter and lost oh well should have sign with Boston!!!
