The Tampa Bay Rays starting pitchers induced more fly balls than any other staff in 2016. In fact, their 41.4% FB rate is the highest of any rotation since the 2013 Oakland Athletics, who put up a 41.5% rate. The 2010 San Francisco Giants would be the next team to have a higher fly ball rate at 41.8%.
Luckily for the Rays, those pitchers were able to suppress their cumulative HR/FB rate to one of the lowest in the league at 12.4%. Considering batters tend to hit balls the hardest to their pull side, the Rays were able to keep that HR/FB rate low by allowing the fewest batted balls in the league to the batter's pull side at 37.
