H AV G = AB Parameters • h (int.) – Hits. • ab (int.) – At bats. Returns float – The batting average. Raises ZeroDivisionError sabermetrics.batting.babip(h, hr, ab, k, sf ) BABIP measures a player’s batting average exclusively on balls hit into the field of play, removing outcomes not affected by the opposing defense (namely home runs and strikeouts). H − HR BABIP = AB − K − HR − SF Parameters • h (int.) – Hits. • hr (int.) – Homeruns. • ab (int.) – At bats. • k (int.) – Strikeouts. • sf (int.) – Sacrifice fly. Returns float – Batting average balls in play..

PO + A FPCT = PO + A + E Parameters • a (int.) – Assists. • po (int.) – Putouts. • e (int.) – Errors. Returns float – The fielding percentage. Raises ZeroDivisionError 1.1.4 sabermetrics.pitching module sabermetrics.pitching.era(er, outs) Represents the number of earned runs a pitcher allows per nine innings – with earned runs being any runs that scored without the aid of an error or a passed ball. 27ER BABIP = Outs Parameters • er (int.) – Earned runs. • outs (int.) – Number of batters and baserunners that are put out while the pitcher is on the mound.
