If it feels to you as though there are more rookies in Major League Baseball than usual, you're not wrong. Between the rules allowing for expanded rosters this year and the need to restock those rosters because of positive COVID-19 tests as well as higher injury rates than normal, teams already have used 231 pitchers and 133 position players who meet the qualifications to be a rookie -- that is, they entered the season with fewer than 130 career at-bats, 50 career innings pitched or 45 career days of service time prior to Sept. 1 in a given season.
