He hasn't played enough to show flaws to work on. Once he is settled in as a major leaguer.. (let's say like 20 games), then maybe start trying to adjust. Right now, it would probably be counter productive. He could be just pressing a little, getting squeezed a little, and finding gloves with hard hit balls. A few of those go on and his approach will reset to his normal approach which he is already quite close to.
