Since 1900, the highest total in a season has been 30, by Red Ames in 1905. Second place on the season list is held jointly by Tony Mullane and Bill Stemmyer, who threw 63 wild pitches in 18, respectively.

The single-season record for wild pitches is held by Mark Baldwin, who threw 83 in 1889 while pitching in the American Association. After Ryan's 277, the next pitcher on the list is Mickey Welch with 274, followed by Bobby Matthews, who threw 253. However, the all-time record belongs to Tony Mullane, who threw 343 in the early years of the game from 1881 to 1894. He also led his league in the category in six different seasons. Nolan Ryan is the modern-era leader in the wild pitches, throwing 277 over his 27 years in Major League Baseball (MLB). A runner who advances on a wild pitch is not credited with a stolen base unless he breaks before the pitcher begins his delivery.īill Stemmyer threw a National League record 63 wild pitches in one season. A run scored on a wild pitch is recorded as an earned run. If the bases are empty, or if the catcher retrieves the ball quickly and no runner is able to advance, a wild pitch is not charged.

No error shall be charged when a wild pitch or passed ball is scored.Ī wild pitch may only be scored if one or more runners advance. Because the pitcher and catcher handle the ball much more than other fielders, certain misplays on pitched balls are defined in Rule 10.13 as wild pitches and passed balls. If the pitch was so low as to touch the ground, or so high that the catcher has to jump to get to it, or so wide that the catcher has to lunge for it, it is usually ruled a wild pitch and not a passed ball. The benefit of the doubt is usually given to the catcher if there is uncertainty therefore, most of these situations are scored as wild pitches. As with many baseball statistics, whether a pitch that gets away from a catcher is counted as a wild pitch or a passed ball is at the discretion of the official scorer. Sometimes the catcher may block a pitch, and the ball may be nearby, but the catcher has trouble finding the ball, allowing runners to advance.Ī closely related statistic is the passed ball. Ī wild pitch usually passes the catcher behind home plate, often allowing runners on base an easy chance to advance while the catcher chases the ball down.

In baseball, a wild pitch ( WP) is charged against a pitcher when his pitch is too high, too short, or too wide of home plate for the catcher to control with ordinary effort, thereby allowing a baserunner, or the batter (on an uncaught third strike), to advance.
