Conversely, scoring a runner from first base on a single<\/a> is such an exciting yet rare event that it only occurs roughly 20 times per season. A baserunner\u2019s dash from first to third base requires speed, skill, agility, daring and intellect. In a few brief moments the runner decides whether to fully commit to taking the extra base, while processing the distance of the hit, how far the outfielder must travel to retrieve the ball, the strength and accuracy of the outfielder\u2019s throwing arm. The baserunner also needs to make an honest assessment of their skills and determine if the gamble is likely to pay off.\r\n\r\nThe \u201cFirst-to-Third Percentage\u201d is calculated by taking the number of successful events where the baserunner advanced from first base to third base on a clean single with no errors on a play divided by the number of opportunities. Therefore any \u201cfailed\u201d events are essentially noting when the runner exercised caution and remained at second base, with a handful of \u201cput out attempting to advance\u201d events to round out the totals.\r\n\r\n\u201cEvent files for most seasons prior to 1974 are each missing a few games.
