Not sure what age you are, but couple thoughts.
2 pitchers is running thin, be good to have a third most likely. Be great to have three with different styles to change up and throw off offenses. We are blessed with that type rotation and its great when they are all throwing good stuff and we can pitch the different looks if needed. Our pitchers are very receptive to the changes and comfortable as a "staff" and not a #1, #2, etc. We are fortunate to have three that could be number ones on alot of travel teams.
Also, coaches never feel they get enough strikeouts, lol, but its not the pitchers job to strike everyone out. Be great if you were in that rare case where you have a dominate pitcher like that, but even so as they get older the bats will catch up. Pitchers job is to place the ball where it can be fielded for the easiest defensive stop and keep the batter off balance and uncomfortable. My dd is a pitcher and does not have a high number of strikeouts necessarily, but a high winning percentage and low ERA. She keeps it low with a ton of spin and most of the time she gets batters to hit into the dirt, rarely getting hit hard consistently.
As far as playing a defensive spot. Thats obviously depends on your depth. This year we have 3 pitchers who all contribute on defense and batting, and one is also our starting SS. On Sundays we try and keep two of them fresh and focused on pitching only where possible and it seems to be working so far.
Keep in mind we are 13u.
Good luck!
