How to Calculate Homerless Innings

Baseball is obsessed with minutiae and statistics. Some, such as earned run average and slugging percentage, require calculated equations. Others, such as won-loss record, innings pitched and homerless innings, simply track performance. Homerless innings are typically considered in terms of a current streak -- the number of innings a pitcher has gone without allowing a home run, whether it's over the fence or the inside-the-park variety.

      Decide whether to track the homerless streak of an individual pitcher or an entire pitching staff, which includes all the pitchers on a given team. This can also be broken into starting pitchers, meaning only those pitchers that begin each game, or relief pitchers, meaning only those which come in after the starter leaves.

      Track when the pitcher or staff last threw a pitch that ended up as a home run. If the most recent home run occurred with one out in the third inning of a seven-inning performance, that pitcher is currently on a 4-2/3 inning homerless streak. Two-thirds of an inning means that the pitcher recorded two outs of one inning, along with the four complete innings without giving up a home run.

    • 3

      Tally the number of innings that the pitcher or staff goes without allowing a home run. If that same pitcher's next two appearances are each seven complete innings before giving up a home run with no outs in the first inning of his following appearance, the streak lasted 18-2/3 homerless innings. The streak ended as soon as another home run was hit off of that pitcher.
