Washington, July 8 : Baseball diamonds - the field upon which the game of baseball is played - are a left-hander's best friend, says a new study.
According to David A. Peters, Ph.D., the McDonnell Douglas Professor of Engineering at Washington University in St. Louis and a baseball fan, the game was designed to make a lefty the "Natural".
"Ninety percent of the human population is right-handed, but in baseball 25 percent of the players, both pitchers, and hitters, are left-handed," said Peters.
"There is a premium on lefthanders for a number of reasons. For starters, take seeing the ball.
"A right-handed batter facing a right-handed pitcher actually has to pick up the ball visually as it comes from behind his (the batter's) left shoulder. The left-handed batter facing the right-handed pitcher has the ball coming to him, so he has a much clearer view of pitches," he added.
Then, Peters says, consider the batter's box. After a right-hander connects with a ball, his momentum spins him toward the third-base side and he must regroup to take even his first step toward first base. In contrast, the left-hander's momentum carries him directly toward first.
"The left-handed batter has a five-foot advantage over the right-handed batter. And that means the lefty travels the 90 feet to first roughly one-sixth of a second faster than the righty. That translates to more base hits for the left-hander, whether singles or extra base hits because lefties are getting to the bases more quickly," he added.
The left-handed pitcher generally is much more difficult to steal off, as, from his stretch, he peers directly at the runner; the right-hander must look over his shoulder and wheel to first base, giving the runner more of a warning of the pitcher's intent, says Peters.
Positions advantageous to southpaws are pitching, first base and right field. For the positions, the advantage is the favorable angles lefties get, enabling them to throw the ball more quickly across the diamond to second, third and home. One position a lefty rarely plays is catcher, for the obvious reason that it is difficult for a southpaw catcher to throw over so many right-hand batters.
"It wasn't all that long ago when first basemen were predominantly left-handed and most right fielders were left-handed. That has changed, at least since the late sixties," Peter says.
According to Peters, there's even a bias toward the lefthander in ballpark design. Right field in most parks is usually shorter than left field because of the preponderance of right-handed hitters.
