Is there any way to increase a pitchers stamina? I currently have a pitcher that has 4 65-80 rated pitches with Stuff, Movement and Control all at 60+. The down side is this pitcher only has a stamina of 35 which is not great for starting. I was wondering if there was any way to increase his stamina or will it go up over a period of time. I am also playing in Challenge mode so editing players is not an option.
