Announcement
1970: The Worth Bat Co. produced the first aluminum bat to hit the market.
1972: Worth produced its first official one-piece Little League model.
1974: The first official NCAA bat was Worth's "Tennessee Thumper."
1989: NCAA imposed a rule that states the length of bat in inches may not exceed by five units the weight of bat in ounces. For example, a 34-inch bat had to weight at least 29 ounces.
1993: Little League received reports of an average of 145 pitchers hit by line drives per year and introduces a Bat Performance Factor (BPF) rating system measuring the exit speed of a ball off the bat. Since the ruling, reports of pitchers hit by line drives has dropped to 20 to 30 per year. "Considering there are more than a million Little League games played each year, with hundreds of millions of pitches, this safety record is nothing less than outstanding," Little League announced in a 2007 press release.
June 6, 1998: Southern Cal defeated Arizona State in championship game of College World Series, 21-14. The NCAA begun investigating ways to curb the offensive explosion of the game.
August 1998: New NCAA rules shrunk bat barrels to 2 5/8 inches or less in diameter and changed the weight-to-length correlation to three units. The BESR (Ball Exit Speed Ratio) protocol required the exit speed of a ball shot at 70 mph toward a stationary bat to be no greater than 94 mph.
March 14, 2007: The New York City Council voted to ban the use of metal bats in high school games in the city. The Public School Athletic League also adopted a pitch count rule to protect the arms of its pitchers.
Spring 2007: Offensive numbers begin to rise again as college players started swinging high-powered composite bats. By 2010, home runs had increased per team per game by 0.26 and teams averaged 0.88 more runs per game than they did in 2007.
June 2009: Twenty of the 25 game-used bats tested during the NCAA Division I playoffs failed the BESR (Ball Exit Speed Ratio) test the bats had passed immediately following production. NCAA begun investigating the performance of composite bats improving over time.
Sept. 2009: The NCAA placed a moratorium on composite bats until they meet BBCOR (Batted Ball Coefficient of Restitution) standards.
Jan. 1, 2011: The NCAA adopts the BBCOR and ABI (Accelerated Break-In) standards that took into account the inertia provided by a moving bat and the tendency for composite bats to become more powerful after repeated use.

Injury rates
• 78 percent of all high school baseball injuries are suffered at five spots on the diamond. In order: first base, home plate, second base, third base and the outfield. The sixth most common location for injuries is the pitcher's mound.• In competition, base runners are injured more often than pitchers.
• 44 percent of all baseball injuries are specifically to the shoulder, arm, elbow, wrist and/or hand; 23 percent of baseball injuries are to the head and face.
• Little League International has tracked injury statistics since the early 1960s. There have been eight fatalities in Little League from a batted ball and six of those occurred with wood bats. The two non-wood fatalities happened in 1971 and 1973.
