On-Base Percentage (OBP) is a key baseball stat that reflects how often a player gets to a base safely. OBP is more valuable than batting average because it counts walks and being hit by a pitch, which means a player with a high OBP could have a lower average but still be a valuable offensive player. OBP is also a vital component of the On-base Plus Slugging (OPS) metric, which offers a more complete picture of a player's performance on offense.
