Are you a walking encyclopedia of batting averages, strikeouts and assists? Do you know the difference between RBI, ERA, WAR, and OPS -- or what stats make up a Triple Crown? If so, you might have what it takes to knock it out of the park with this baseball stats quiz!
Unlike many other sports that are slightly more subjective, baseball lends itself well to numbers. Thanks to the ready availability of statistics on everything from individual players and games to teams and leagues, it's pretty easy to determine exactly which player should hold the title of best pitcher of all time or home run king. After all, numbers don't lie.
What's really interesting about baseball stats, however, is the way they allow fans and analysts to look beyond some of the more obvious feats, like homers or strikeouts. Modern baseball statistics are a math of their own, and can be applied to almost any player or action.
That means someone who might not make headlines for consistently knocking it out of the park could still be recognized for his phenomenal shortstop skills or assists. It also means that once overlooked players throughout history are now winning new respect as computers run the numbers on largely forgotten careers.
