WHO HAD A BETTER YEAR, NOMAR GARCIAPARRA OR ICHIRO SUZUKI?
The Runs-Created Approach In 2004 Seattle Mariner outfielder Ichiro Suzuki set the major league record for most hits in a season. In 1997 Boston Red Sox shortstop Nomar Garciaparra had what was considered a good (but not great) year. Their key statistics are presented in table 2.1. (For the sake of simplicity, henceforth Suzuki will be referred to as “Ichiro” or “Ichiro 2004” and Garciaparra will be referred to as “Nomar” or “Nomar 1997.”) Recall that a batter’s slugging percentage is Total Bases (TB)/At Bats (AB) where TB = Singles + 2 × Doubles (2B) + 3 × Triples (3B) + 4 × Home Runs (HR). We see that Ichiro had a higher batting average than Nomar, but because he hit many more doubles, triples, and home runs, Nomar had a much higher slugging percentage. Ichiro walked a few more times than Nomar did. So which player had a better hitting year? When a batter is hitting, he can cause good things (like hits or walks) to happen or cause bad things (outs) to happen. To compare hitters we mu
