90 feet from pitcher to batter --> no, it is 90 feet along the base paths, but it is 63.6396 feet from the pitcher's mound to home plate
100 MPH = 146.666667 Feet Per Second
63.6396 ft / 146.6667 ft/s = 0.4339 seconds = time pitched ball to reach batter
so if you factor in that the batter has to first see the ball, detect its a fastball, recognize its location, and if in the strike zone, attempt to hit it (all in less than a second), you can probably agree: "man, these guys are good"
100
No. Only a very few of them can throw 100 mph. They don't exceed 100 mph by much - 101, 102 is tops. Most of them throw a fastball in the 90's, and a few have a fastball in the 80's.
4 seam fastball, 2 seam fastball, split, 12-6 curve-ball and slider
