Jeff Bianchi had only 26 days on an active roster in 2012 and less than 130 at bats in 2012 so 2013 is considered his one and only rookie year. He has more than enough at bats this year. Tyler Thornburg was only on the active roster for 21 calendar days last year before the 9-1 date but now he has exceeded the innings threshold. This is his one and only rookie year. I won't go into big details, but earlier in the year I added up the service time for Alfredo Figaro and this is his one and only rookie year because he has exceeded the innings threshold. Logan Schafer is a rookie this year only. He never played before Sept 1st on a roster before 2013, and he now has exceeded the at bats requirement for rookie status. Hand is a rookie this year only. He has exceeded 50 innings. Peralta is a rookie this year only. He has exceeded both the innings and service time. Cannot be considered a rookie next year at all. Scooter is a rookie this year and this year only because he has more than 130 at bats. Wow get this... sitting on the fence with Sean Halton. He CANNOT be a rookie in 2014 because according to what I found he spent 46 days on the roster before September 1st this year. Wow. Doug failed on roster manipulation there. So by one day, and not the at bats threshold (cause it is either or,) halton is screwed for rookie status next year. K Davis is a rookie this year only, because he has spent more than 45 days on the active roster before Sept 1st. He is very close to exceeding 130 at bats as well, but it is either or. Caleb Gindl as of this writing has 118 at bats but he has also exceeded the service time limit just like K Davis. I show about 58 days on the roster before 9-1. Segura burnt his rookie year last year in 2012 with 151 at bats, twenty one over the limit. I have conflicting dates as to the amount of time Kintzler spent on a big league roster before this season. If this is indeed considered his rookie year, he is doing well, but you know relief pitchers don't get any love. Jim Henderson- Only accumulated 37 days on the roster last year before Sept 1st and this is his one and only rookie year because he has exceeded 50 innings. Doing well for a rookie year. Blake Lalli of all people has not gotten anywhere close to the at bats threshold, but I show that he was on the Brewers roster long enough this year to make it over 45 days total for his career, and he CANNOT be a rookie next year based on that! Other Random Names that are not rookies: Juan Francisco, Chris Narveson, Mike Fiers, and Marco Estrada Determining rookie status: A player shall be considered a rookie unless, during a previous season or seasons, he has (a) exceeded 130 at-bats or 50 innings pitched in the Major Leagues; or (b) accumulated more than 45 days on the active roster of a Major League club or clubs during the period of 25-player limit (excluding time in the military service and time on the disabled list).
