Just the other day, I posted Part One of my article looking at the players who are affected the most by changing league scoring from Batting Average to On Base Percentage (OBP). Today, Part Two accomplishes that same goal, but looks at each position. Remember, the goal of this article is NOT to rank players based on OBP. The goal of this article is to highlight certain players that substantially benefit or lose value from the switch from Batting Average to On Base Percentage. 



Remember, the switch from Batting Average to OBP changes the value of players by varying degrees. Some players who would have negative value due to their poor Batting Average become positive players (see Dan Uggla). Some players who have above average Batting Averages become less valuable in the OBP setting. The following charts represent the players that gain and lose the most value by switching to the OBP format at each position. (All player data was gathered from Fangraphs.com. I used the past two seasons as a sample size.)
