Potential 2nd Half HR/FB Decliners
For me personally, it feels like offensive surprises and busts are harder to evaluate during the year because we have fewer tools to analyze. Power is one skill that is difficult to decide how real a spike or drop is, but Jeff Zimmerman has been mentioning a tool at Baseball Heat Maps that gives you the distance of a hitter’s batted balls, which may really help in this type of analysis. In the past, I have used the ESPN Home Run Tracker site to help determine how flukey a change in HR/FB ratio is, but I think looking at the raw average distance is a less flawed method. I looked at the five hitters whose HR/FB ratio has increased the most this year and then added their 2011 and 2012 average home run plus fly ball distances to the table.
