The trend in Major League Baseball has been about getting the ball airborne, however the Tampa Bay Rays went the other way in 2018.
The Rays fly ball rate fell from 36.6% to 32.4%. Their line drive rate rose to 22.1% from 20.0% along with a rise in ground ball rate to 45.6% from 43.4%.
Hitting to the opposite field might help, but the biggest factor in BABIP is batted ball type.
