Zachary struggled to hit home runs over the summer and researched why. He learned that hitting the ball in the "sweet spot" of the bat, with the proper angle and enough speed, transfers maximum energy to the ball. His research showed increasing the mass of the bat or velocity of the swing can boost the distance of a hit. Zachary concluded he had been swinging incorrectly and not making contact in the right part of the bat, resolving to apply what he learned.
