SwingAway

The Original Swingaway was introduced to the Seattle Mariners in 1995, which created a Buzz with the professional teams and ballplayers. Within a few short years all 30 MLB teams and over 250 MLB Players owned Swingaways. Eventually the top baseball and softball college, high school, and travel programs plus the US Olympic Teams owned Swingaways. The Swingaway continues to be validated at the highest levels of the games of baseball and softball but it's been relatively unknown by the younger teams and players, that included millions of players in the United States alone. The design has been modernized, re-engineered and redesigned the prominent Batting Station for mass production, with a New Patent for the revised design of the original Swingaway Hitting Machine. Today the New Swingaway model is one of the Top-selling and highest rated Hitting – Batting training aids. It's guaranteed to help any player develop proper swing mechanics.
