- Launch angles 8-12 degrees at 90 mph exit velocity = line drives for 90% basehits. 12-15 degrees at less than 90 mph = generally fall for hits. 23-35 degrees at 90 mph exit velocity= HR’s
- Line drives yield the best OPS followed by fly balls and then grounders
- 12 degree launch angle with 80 mph exit velocity produces 80% basehits
- Most balls hit at less than 60 mph exit velocity remain in the infield with a few rolling into the outfield
- Launch angles of 30 degrees will result in 20% HR’s
- Average MLB four seam fastball 93 mph
- Average MLB 2 seam fastball 91 mph
- Average MLB slider 84 mph
- Average MLB changeup 83-84 mph
- Average MLB RHP CB 78 mph
- Every increase in one MPH in bat speed = 8’ more distance of ball flight
- Bat speed is measured at the barrel in MPH- 75-80 is good
- Bat quickness is measured from launch to contact .16/100is good
- Keep head movement on the swing to less than 5”
- The kinetic link disassociation measurement refers to the degrees the lower half leads the upper 25 degrees is average
- QAB = hard hit out, 7 pitch out, hit, BB, HBP, situational execution
- There are about 54 locations in the strikezone
- 90 mph fastballs lose velocity at one mph per seven feet and drop three feet on the way to the plate
- The average MLB exit velocity on a fastball is 88, off speed 85
- MLB hitters batted ball percentages-line drives 21%, groundballs 44%, fly balls 35%, pop ups in the infield 11%
- An increase of one MPH in bat speed will lead to an additional eight feet in distance
- Most MLB hitters have a launch angle close to 13 degrees
- 17% of MLB pitchers average less than 90 mph
- Bat speed is roughly 6X more important to exit velocity than pitch velocity
- 35% of all the balls put in play go up the middle
- 2016 MLB stats: avg-.257, OBP .328, K 20.9%, BB 8.7%
- 25 degree launch angle at 95 mph exit velocity = HR
