Calculator<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Q1: What is on base percentage?<\/h3>\n\n\n\n<p><strong>A1:<\/strong> It measures how often a player reaches base through hits, walks, or hit by pitch.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Q2: How do you calculate OBP?<\/h3>\n\n\n\n<p><strong>A2:<\/strong> Add hits, walks, and HBP, then divide by total plate appearances.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Q3: What is a good OBP?<\/h3>\n\n\n\n<p><strong>A3:<\/strong> Around .320 is average, while .400+ is considered elite.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Q4: Why is OBP important?<\/h3>\n\n\n\n<p><strong>A4:<\/strong> It shows how often a player avoids making an out and contributes to scoring chances.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Q5: Is OBP better than batting average?<\/h3>\n\n\n\n<p><strong>A5:<\/strong> Yes, because it includes walks and hit-by-pitches, giving a fuller picture.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hits (H)
