What is Checked Swing? When a batter begins to make an offering at a pitch but halts his swing before making a genuine attempt, he is said to have produced a checked swing. If the ball does not arrive in the strike zone during such a swing, the pitch is called a ball.
In baseball statistics, walks hits per inning pitched (WHIP) is a sabermetric measurement of the number of baserunners a pitcher has allowed per inning pitched. WHIP reflects a pitcher's propensity for allowing batters to reach base, therefore a lower WHIP indicates better performance. WHIP is calculated by adding the number of walks and hits allowed and dividing this sum by the number of innings pitched. The stat was invented in 1979 by writer Daniel Okrent, who called the metric innings pitched ratio at the time.
