My reference to 45 minutes does not reflect a pitcher that has already gone the distance in her normal routine. Most pitchers that have already thrown some innings can warm up quicker as mentioned in the other quote.
My reference to the 45 minutes does not mean they throw the entire time. They need the time for numerous reasons, both mentally and physically. Our warm up does reflect the warm up used in practice but is a condensed version with certain steps left out. One is the wrist snap that I instruct to the girls is a practice drill---not a warm up drill. However, I do tell the girls if they feel better to start out with snaps it's their warm up not mine. Do what they feel good about to insure they are ready and confident.
During our 45 minutes that I recommend they allow before pitching their first 7 inning game of the day, they stretch their arm, they'll take a break or 2 to drink and discuss any issues with the catcher & coach on what pitches need to be adjusted. The number of pitches thrown during that time will vary but I'm sure it's much less than a couple hundred. For younger girls, some of that time is spent chasing the overthrows. lol. They need about 45 minutes. They do not need 200 practice pitches.
Young ladies are very regimented about their warm up and don't like change any more than they like being rushed. I suggest coaches allow more time to let a girl get ready, even if you think she's slacking off. How many coaches have seen a pitcher start a game and gets slammed her first 2 innings before settling in and taking control? This would be an indicator to me she wasn't game ready when she started and needs more time in the future.
I always warm all pitchers up with the initial warm up drills, then focus on getting the primary pitcher ready. I'll have the second pitcher throw lightly later on, perhaps between innings, to simulate an inning or 2 for her. That way if we need her later, she's nomally within a few pitches of being sharp.
I do agree you should not leave a girl's "A" game in the bullpen. A good coach should be able to tell when a girl is ready or needs a little more time.
