What Determines Rookie Year?

[BKL]

When is a year officially considered the player's rookie year, and also would make them eligible for Rookie of the Year? I wonder because a player in my league won Rookie of the Year, but I noticed last year he also played 20 games in the Majors.

It should be 130 AB, 50 IP, or 45 days on the 25-man roster prior to the expansion of rosters on September 1st. However, OOTP seems to disregard the third standard entirely as I've seen some guys wind up a season with two years and zero days of Major League Service Time and be considered rookies, receiving Rookie of the Month Awards all the way through that second season. This shouldn't be happening, but it may be difficult to code. I don't expand the rosters in September, so I consider any player with 1 year and 45 or more days of service time to be ineligible when I make my three selections for Rookie of the Year.

A player will be considered a rookie unless he has acquired more then 130 at-bats, 50 innings pitched, or more than 45 days of service time during the 25 man roster period. I also believe he can't be older than 27 for ROY eligibility.

Age limit can't be true because the guy who the award is named after won it when he was 28. Also, Kazuhiro Sasaki was 32 when he won it in 2000, so I doubt there is an age limit on ROY.
