Jason Giambi now spends his time taking care of his young children rather than clobbering baseballs. But the former baseball star is keeping his hand in the game through a new virtual reality practice system.
Giambi, 44, gives hitting tips in a training program unveiled last week by Eon Sports VR. Using a virtual reality headset, players simulate at-bats, gauging balls and strikes and pitch delivery.
"You actually feel like you're facing the pitcher. He's going through his windup, he's going through his pitches. You can even pick up seams on the baseball," Giambi told CNBC.
