Todd Frazier has experienced a power explosion this season, but is the surge sustainable?

The Cincinnati Reds third baseman has a 22.4% home run/fly ball rate, which may be primed for regression.

Over the course of his career, Frazier has seen his average fly ball get longer and longer. In 2012, his average fly ball went 280 feet. This season that figure is up to 303.8 feet.

Where his fly balls are going has changed this season as well.

"Frazier has always been a guy who had an even distribution of his home runs across fields, with a slight lean toward right field for his fly balls. Not in 2015," writes Owen Watson. "We can see his propensity to pull the ball has increased dramatically this season, with all but one of his home runs going to left or center field. We’ve seen the kind of power jumps that players can have when they start pulling their fly balls more; couple that tendency with a major increase in fly-ball distance (into top-20-in-the-majors territory), and you have the makings of a big year."
