In baseball statistics, on-base percentage (OBP; sometimes referred to as on-base average/OBA, as the statistic is rarely presented as a true percentage) is a statistic generally measuring how frequently a batter reaches base. Specifically, it records the ratio of the batter's times-on-base (TOB) (the sum of hits, walks, and times hit by pitch) to their number of plate appearances. It first became an official MLB statistic in 1984.
We all know that a .260 batting average is about average while a mark of .200 is quite poor. We know that .300 is a good figure and that .340 will often win the batting title. However, the values of an average, good, or bad OBP are not so ingrained in us. In 2013, the major league OBP was .318. Among players who qualified for the batting title, Detroit's Miguel Cabrera had the highest OBP with a mark of .442. Kansas City's Alcides Escobar posted the lowest figure at .259. Below, I have included a table that shows OBP for various percentiles in 2013. For example, Matt Holliday's OBP of .389 was better than that of 90% of qualified batters in 2013.
Every baseball player would love to be able to hit for power, but not every baseball player is a natural like Bryce Harper. There are a lot of things that go into a powerful baseball swing, and no one swing method or form is the right fit for all hitters. However, there are some "Cream and Clear"-free ways that can help all players add power. With the strategy and preparation, you can develop both your mind and body for power hitting as well as improve your form regardless of your preferred stance or swing.
While batting average is a useful tool for measuring a player's ability at the plate, it isn't all-encompassing. For instance, batting average doesn't take into account the number of times a batter reaches base via walks or hit-by-pitches. And it doesn't take into account hit type (with a double, triple or home run being more valuable than a single).
