With the departure of Billy Hamilton, the Cincinnati Reds outfield defense has gone from one of the best in baseball to one of the worst — at least according to analytics data.
Baseball Savant, a website run by MLB.com. presents data based on some of the newer analytics, including a comparative measure of individual outfielders’ defensive acumen called Outs Above Average.
According to Baseball Savant:
Outs Above Average (OAA) is the cumulative effect of all individual Catch Probability plays a fielder has been credited or debited with, making it a range-based metric of fielding skill that accounts for the number of plays made and the difficulty of them.
