Quality start
In baseball, a quality start (QS) is a statistic for a starting pitcher defined as a game in which the pitcher completes at least six innings and permits no more than three earned runs. The quality start was developed by sportswriter John Lowe in 1985 while writing for The Philadelphia Inquirer. He wrote that it "shows exactly how many times a baseball pitcher has done his job." The quality start was created to be an accurate measure of a starting pitcher's performance. However, the implied earned run average (ERA) of a minimum quality start has been criticized, with Tim McCarver noting "three runs for six innings ... means the ERA would be 4.50 ... Rubbish."
