Batting va pitching statistikasi
Beysbol statistikasi: AVG, OBP, SLG, OPS, ERA va WHIP
Ko‘p ishlatiladigan batting va pitching rate stats, ularning formulalari va bitta raqam nimalarni ko‘rsatishi yoki ko‘rsata olmasligini tushuntiruvchi amaliy qo‘llanma.
AVG, at-bat va plate appearance
Batting average (AVG) hits sonini at-bats soniga bo‘lish orqali hisoblanadi: AVG = H / AB. At-bat (AB) plate appearance (PA) bilan bir xil emas. Walk, hit-by-pitch va ayrim sacrifice AB qo‘shmasdan PA qo‘shishi mumkin, shuning uchun PA odatda AB dan katta.
OBP, SLG va OPS
On-base percentage (OBP) batter formula hisoblaydigan hit, walk va hit-by-pitch kabi natijalar bilan base-ga qanchalik tez-tez chiqishini ko‘rsatadi. Slugging percentage (SLG) total bases-ni at-bats-ga bo‘ladi va extra-base hits-ga ko‘proq vazn beradi. OPS = OBP + SLG.
ERA va innings pitched
Earned run average (ERA) to‘qqiz innings uchun ruxsat etilgan earned runs sonini ko‘rsatadi: ERA = 9 × ER / IP. Innings pitched outs orqali hisoblanadi; har bir out inning-ning uchdan biri. Odatdagi yozuvda 5.1 IP besh va uchdan bir, 5.2 esa besh va uchdan ikki innings degani, o‘nli kasr emas.
WHIP va statistik kontekst
WHIP = (BB + H) / IP: walks va ruxsat etilgan hits yig‘indisi innings pitched-ga bo‘linadi. Past WHIP odatda shu ikki yo‘l bilan kamroq baserunner berilganini anglatadi. Hit batters, errors va fielder’s choices WHIP-ga kirmaydi, bitta stat batter yoki pitcher-ni to‘liq tushuntirmaydi.
