Grandal worked on his swing this offseason with the intention of increasing his launch angle, The Athletic reports.

Grandal is attempting to join the launch angle revolution. Notable success stories among those who have attempted to improve their slugging percentage by hitting more balls in the air include Josh Donaldson, J.D. Martinez, and Grandal's teammate Justin Turner, though not everyone has benefited from changing their swing. Rob Arthur of FiveThirtyEight found that only about half of the hitters who increased their launch angle saw the desired improvements. Don't assume that Grandal will automatically be better this season, but there's at least a chance that he finds some untapped power in 2018.
