The catcher might disagree but most would say the player has a pretty good swing. One minor thing that would be easy to improve is the bat angle. While not terrible the player is holding the bat a little flat and never gets it in the slot before starting his swing. If you’re not familiar with what I am talking about visualize the bat head being directly above the helmet at the start of the swing and not pointing toward the third base dugout. This may sound minor but it is very important if you want the bat to get to the ball on the most efficient path. While you can find a something different about every major leaguer's stance I think you will find that when they trigger the bat is almost always in the slot and never flat.
