In Major League Baseball, Louisville Slugger bats are used by over 60 percent of all Major League Players, including the game's best hitters like Ken Griffey, Jr., Kevin Youkilis, and Derek Jeter.

Compared to the great sluggers of yesteryear, today's pros use more lightweight bats with thinner handles.  Approximately 40 percent of the players using Louisville Slugger bats have the bats cup balanced, which means up to three-quarters of an ounce of wood is scooped out of the end of the barrel, also making the bat lighter.  Lighter bats help today's pros swing faster and send the ball further.

Most bats today are made from northern white ash, but a growing percentage of professional players, currently about 40 percent, have started requesting bats made out of maple.

The Louisville Slugger is the Official Bat of Major League Baseball.
