During the 2023 season, MLB pitchers recorded a quality start a little over 34% of the time, with a quality start being identified as at least six innings pitched and three earned runs or less allowed.
Last season the average quality start lasted 6.5 innings and resulted in 1.30 earned runs allowed for an average ERA of 1.80.
Teams that get a quality start won 69% of the time in 2023 and if only one of the two starters in a game registers a quality start that number jumps to 79% for the team with the quality start.
