1 Bats and a multitude of changes for 2012 By: Me

2 A quick history of bats Wood – Early players used to make their own – 1884 saw Louisville Slugger make a wood bat Metal – First patent for a metal bat was 1924 – First metal bat was made by Worth in 1970

3 A quick history of bats Titanium – 1993: Easton and Worth introduce them – This increased the sweet spot – Z core bats Composite – Made of carbon fiber composite materials – Further increased the sweet spot

4 The Sweet Spot Its all about energy and bat vibration: – The further away from the sweet spot you hit the ball, the more vibration (sting) you have and less power – If you hit the ball perfectly on the sweet spot, you will feel ZERO vibration This is true for ALL BATS All of the energy is directed from the bat to the ball

5 The Sweet Spot Wood Bat – About 3 Metal / Composite Bats – 6 or more BBCOR – Apparently is around 4 – Some claim it is 3

6 Super Bat Trampoline Effect This only exists on a metal or composite bat – High end bats are made of double walled construction The outer wall of the bat compresses as the ball hits it, and then trampolines the ball back – 5 to 7 mph is gained in ball exit speed – For every 1 mph of exit speed off the bat, the ball travels about 4 or 5 feet

7 What was the old bat regulations? Ball Exit Speed Ratio (BESR) – June 2001 – National Federation of State High School Associations (NFHS) – All bats must have a BESR stamp on them to be legal for use in high school starting in 2003

8 BESR – The maximum BESR limit was.728 They used a 70 mph pitch, hit it with a wood bat, 6 from the end of the bat, and came up with the number Huh? – Ratio of the speed at which the ball exits the collision point with the bat, divided by the combined speed of the bat and ball before collision = BESR – Bats also have to be -3 (i.e oz.)

9 Quick visual of -3 bats

10 So why change from BESR to BBCOR? NCAA: – Average home runs per game were close to one per game

11 The fix: BBCOR Batted Ball Coefficient of Restitution (BBCOR): – How its determined: If the ball and bat are moving towards each other at a relative speed of 160 mph (80 mph pitch / 80 mph bat speed), it has to come off the bat after collision at 80 mph MAXIMUM (0.5) – This is the Batted Ball Coefficient of Restitution All bats for 2012 have to have this stamp

12 BBCOR Batted Ball Coefficient of Restitution (BBCOR) – All non-wood bats have to meet BBCOR standard They used to only have to meet the BESR standard – Reasoning: Minimize risk, improve play and increase teaching opportunities Basically, the Gorilla Ball era is OVER

13 BBCOR v. BESR Example of BESR v. BBCOR bats: – Jump up and down on a concrete floor (BBCOR) – Jump up and down on a trampoline (BESR) – Difference in height of the jumps is basically the difference in the design of the bats Trampoline Effect

14 Independent Tee Test Batted ball speed off of a tee: – Wood = 75 mph average – BBCOR = 84 mph average – BESR = 92 mph average – 1 mph = 4 – 5 feet, or so, of distance

15 Why are Composite bats banned? Here is the problem: – Even though they are designed to work like wood and metal bats, they do not – Accelerated Break In (ABI) for these bats actually makes them hotter than anything on the market – IF a composite bat can pass the BBCOR test, it could (key word) be subjected to debate for legal for use

16 Have the BBCOR bats changed the game? NCAA Division I Baseball 2010 and 2011: – Home runs per game =.94 to.47 (exactly ½) – Batting Average =.301 to.279 – ERA = 5.83 to 4.62

17 Offensive Explosion 2011 Team Statistics – Average:.314 – Hits: 212 – 2B: 41 – 3B: 5 – HR: 24 (3 rd Place for single season) – 5 of 9 starters hit over.300
