In an effort to train for this opportunity, he drilled a hole in a baseball, fed his surfboard leash through it, and attached it to a pole. This allowed him to continually work on his swing without chasing down the ball. ​ Since then, SKLZ has grown into the global leader in sport training equipment by offering product solutions for every level of athlete. Innovating equipment across baseball, soccer, golf, basketball, and more, SKLZ products are designed to target specific skill sets to unlock athletes' full potential throughout their athletic journey. ​ From our groundbreaking beginning with the Hit-A-Way Baseball Trainer, to continually evolving to meet the needs of every athlete, SKLZ stays on the cutting edge of training producing products that are made by athletes for athletes. When it comes to choosing your training partner, never settle. Review: Excellent - This is great. No complaints at all.
