I don't personally focus too much on how many pitches a pitcher has. Hell sometimes you can screw them up by making them throw different pitches. Look at Osuna for the Jays. He basically had one pitch that worked perfect for him and they tried to add in a couple other pitches and he has been horrible since the All Star break. Poms until his last start has been good for us. If a pitcher has one or two good pitches I'm fine with it as long as he plays well.
