I never did scrimmage games as a part of tryouts. I had too much coaching/teaching to do and so, didn't want to spend my time in that way. We had 3 days of tryouts before 1st cut. Then, typically had to wait a couple of days before basketball players tried out. In Illinois, there is an overlap of those sports seasons. The first Saturday after the team was picked, we had our parent's meeting and then, pretty much concentrated on skills development. Instead of scrimmages, we did live BP where our staff threw and inning or two to hitters who rotated in. Instead of fielding balls from scrimmages, instead we put runners on the bases and one in the left handed batter's box and the pitcher delivered a pitch. I then hit the ball somewhere. I loved situational infield/outfield like this and could get a lot more done than in a scrimmage.
