How many at-bats is it requried to be able to be egbile for thre rookie of the year award in The MLB?

A rookie is a player who hasn't accumulated 130 at-bats or 50 innings pitched in previous seasons and hasn't spent 45 or more days on 25-man active rosters, not including times when the active list is expanded to 40.

Copy and pasted from Baseball-Almanac:

Eligibility requirements were set forth in 1971 and a rookie was formally defined as a player with less than one-hundred thirty at-bats, a pitcher with less than fifty innings pitched, or anyone with less than forty-five days on any Major League roster.

I'm pretty sure it only takes one at-bat to qualify...but there's no way you'd get the numbers to win it based on a single at-bat.

It depends..... As many times as you go poopie on the potty each year is how many at bats it takes
