Here's a quick example: Ichiro Suzuki had a record 262 hits in 2004. He also walked 49 times and was hit by 4 pitches. The sum is 262 + 49 + 4 = 315. He had 704 at bats, 49 walks, 4 hit by pitches, and 3 sacrifice flies on the year. That sum is 704+49+4+3=760. Dividing 315 by 760 gives the on base percentage of .414. That's not too bad, but it's not much higher than his batting average, which was an impressive .372. By comparison, Jose Bautista had a respectable batting average of .286 in 2014, but still reached base at a very strong .403 clip, helped by 104 walks.
The way you hold the handle of a baseball bat determines the speed and power of your hit. If you choke up on the handle and hold the bat closer to the barrel, you are gaining bat swing speed but losing on the hitting power. If you hold closer to the bottom of the bat, you gain hitting power and momentum but lose on the speed. You should extensively practice with both methods of holding the handle and find the golden mean where you are able to swing quickly and still hit the baseball as far as possible.
Probably very few of you except a few Cincinnati residents saw this one coming. Yes, Michael Lorenzen is the current hitting pitcher batting king, according to OPS. The lion's share of the 25-year-old's at-bats (36) came in his rookie season in 2015 when he tallied 9 hits including a triple. Now that he's moved to the bullpen, the opporunties will be fewer. Last year he homered once in five at-bats and this year he's had just three at-bats so far, but he added another home run as a pinch hitter!! So Lorenzen has joined the holy club of pinch-hitting relief pitchers. Tip of the cap!
The last notable disadvantage of OBP is that it is not park or league adjusted. It is easier for players to post a higher OBP in parks such as Fenway Park or Coors Field than the Oakland Coliseum or Petco Park. Likewise, OBP has fluctuated throughout time. Carl Yastrzemski led the American League with an OBP of .395 in 1965. However, in 2001, Jason Giambi put up the highest mark at .477. There are ways to adjust numbers for park and league context, but we'll save that topic for a later date.
