Trevor Story was one of the great surprises of 2016. He continues to be of interest early in 2017.
Story has always been a fly-ball hitter, which is an attractive trait for a player who calls Coors Field home. In his eight minor-league stops, Story hit more fly balls than ground balls six times. As a rookie last season, he posted a 0.62 GB/FB ratio and a 47.1 FB%.
This season?
Story has gone full Schimpf on us. He ranks second only to Schimpf in GB/FB ratio and second in GB/FB ratio (minimum 100 plate appearances) since batted-ball ratios have been recorded.
Story was already an extreme fly-ball hitter. Now he’s even more extreme — nearly the most extreme on record.

Numbers entering play on Thursday.
Story’s proclivity for fly balls doesn’t appear to be the result of fluky, early-season sample size. Consider: his average launch angle is 32 degrees, nearly double his 2016 average (16.7 degrees). A number of batted-ball metrics are near stabilization points. In the majors, Story ranks second only to Schimpf (33.1 degrees) in average launch angle. I haven’t seen any reports on Story’s apparent swing alterations or changes to philosophy early this season, but it appears as though he’s up to something.
We’ve written quite a bit about the uppercut philosophy this spring, and more and more MLB hitters appear to be buying in. The league’s average launch angle has inched up from 10.0 degrees in 2015, to 10.6 degrees in 2016, to 10.9 in 2017.
The question is, when does a hitter become too extreme in approach?
