In 1938, Johnny Riddle played for the Boston Bees. On Base Percentage (OBP) is considered by many to be a better measure of a great hitter than the Batting Average. It is calculated with the formula (Hits + Walks + Hit by Pitch) / (At Bats + Walks + Hit by Pitch + Sacrifice Flies). In 1938, Johnny Riddle had 57 at bats, 16 hits, 4 walks, and was hit by the pitch 0 times. Sacrifice flies weren't counted before 1954. That gives him an On Base Percentage of .328. Slugging Percentage (SLG) is a popular measure of a batter's power. It is calculated as (Total Bases) / (At Bats). Another way to look at it is (Singles + 2 x Doubles + 3 x Triples + 4 x Home Runs) / (At Bats). In 1938, Johnny Riddle had 57 at bats, and hit 15 singles, 1 double, 0 triples, and 0 home runs, for a .298 slugging percentage. Being able to get on base and to hit for power are two of the most important offensive skills in baseball, so the On Base Percentage and Slugging Percentage are often added together. On-base plus slugging (OPS) is a sabermetric baseball statistic. The best hitters in Major League Baseball can achieve an OPS of .900 or higher. In 1938, Johnny Riddle had a .328 On Base Percentage and a .298 Slugging Percentage for an OPS of .626. Runs Created (RC) is a baseball statistic invented by Bill James to estimate the number of runs a hitter contributes to his team. There are a number of formulas used to calculate it. One of the simplest is (On Base Percentage) × (Total Bases). In 1938, Johnny Riddle had a .328 On Base Percentage and 17 Total Bases for 5.57 Runs Created.
