MLB lowered mound and tightened strike zone and tries an experimental ball 

1969 – In addition to this year’s lower mound and tightened strike zone, Major League Baseball tries an experimental ball with 10% more resiliency for a spring training game between the Mets and Tigers in Lakeland, Florida. It has an all-rubber center instead of a cork and rubber core, and the seams are higher than the regular ball. Mets pitcher Don Cardwell surrenders three home runs in the 4th inning to Dick McAuliffe, Norm Cash, and Gates Brown in the Tigers’ 7 – 4 victory. Tomorrow, in Phoenix, Arizona, the same ball is used in the Giants’ 13 – 1 win over the Angels, with Bobby Bonds hitting the only two homers off George Brunet. The players agree the ball is definitely livelier and sounds louder coming off the bat.
