This is our sixth annual list of possible breakout players based on Spring Training statistics. We researched the value of Spring Training stats a few years back and it was quite revealing. For the most part, we agree with the common perception that they don't have value. A bad spring training means nothing. An average spring training tells us nothing. Nevertheless, we did find that when a player has an exceptional spring, it does suggest a better than 60% chance they will take their game up a notch. It applies to teams as well.
We define "exceptional spring" as a positive difference between a hitter's spring training slugging percentage and their lifetime slugging percentage of 200 points or more.
We analyzed hitters with both a minimum of 200 career regular season at bats and with a minimum of 40 spring training at bats (through spring training games of Tuesday, March 30) and found the following 18 players.
