when are you considered a rookie in mlb
Rookie To qualify as a rookie in Major League Baseball, a player must not have exceeded 130 at bats or fifty innings pitched in the majors, and also fewer than 45 days on the active rosters of major league clubs (excluding time on the disabled list or any time after rosters are expanded on September 1) in their previous seasons.[3] Major League Baseball awards the best rookie with the Major League Baseball Rookie of the Year Award, as voted upon by the Baseball Writers' Association of America.
Aaron Judge The Yankees selected Judge in the first round of the 2013 MLB draft. After making his MLB debut in 2016 and hitting a home run in his first career at bat, Judge went on to have a record-breaking rookie season in 2017. He was named an All-Star and won the Home Run Derby, the first rookie to do so. Judge ended the season with 52 home runs, breaking Mark McGwire's MLB rookie record of 49 and the Yankees' full-season rookie record, previously held by Joe DiMaggio with 29. He also hit 33 home runs at Yankee Stadium, breaking the record of 32 set by Babe Ruth in the Polo Grounds in 1921, and set the record for most walks in a rookie season with 127.[1] He won the American League's (AL) Rookie of the Month Awards for April, May, June and September, as well as the AL's Player of the Month Award for June and September. Judge was unanimously selected as the AL Rookie of the Year for 2017 and placed second, behind José Altuve, for AL Most Valuable Player.[2]
