Perhaps, but the real inexplicable move was to then allow Uribe to face Will Smith! At that point screw the righty-righty "rule" if your pitcher just doesn't have it. Murph's players bailed him out in the top of the 7th.
Murphy is a great manager but this R-R matchup stuff doesn't mean a thing if your pitcher just doesn't have it. Sometimes I think this R-R/L-L theory isn't always gospel.
