If a "pitcher" is doing the work outside of regular practice, and has something other than a fastball to work with, being asked to come into a game with only five warmup pitches or some other limited warmup is definitely a challenge but is not "throwing her to the wolves". Even if the coach publishes a pitching lineup, every "pitcher" should expect to be called on at a moment's notice and should do some level of pre-game warmup.
"Throwers" can get away with just firing away because the coach is just expecting speed anyway. But the defense better be on their toes.
