Rookie Status

Leave seasons with default "First" to "Last"
Rookie Explanation

Rookie status has changed over time, but for this output we are using the following standard.

Since 1971, rookies are players who have not reached
130 at bats,
50 innings pitched, or
45 days of service time prior to Sept. 1.

Before 1971, rookies are players who have not reached
90 at bats,
45 innings pitched, or
45 days of service time prior to Sept. 1.

For the service time measure, we are requiring the player did not reach 78 days of service at the end of a season. We have service time data only back to 2009.

The pre-1971 standard is applied to all seasons back to 1871 even though it was not the standard of the time.
