5 wild pitches in one game.Number of occurrences: 5. Most recently, Freddy García, April 10, 2012. Rick Ankiel of the 2000 St. Louis Cardinals and Bert Cunningham of the 1890 Players' League both threw five wild pitches in a single inning.

Three errors on one play. Number of occurrences: 4. Most recently committed by Los Angeles Dodgers vs San Diego Padres, September 8, 2014. Yasiel Puig bungled a throw to first base. A. J.

^This may seem impossible. However, by definition a perfect game requires more than simply retiring the first 27 batters in order; it also requires that the pitcher's team wins, and that the pitcher completes the entire game. See perfect game for more details.
^These six events may be the only times in the history of baseball when a team has deliberately and with premeditation allowed a run to score by the opposing team for strategic purposes. It is true that there are cases where a particular choice of defensive alignment may make scoring more likely, and there are cases where decisions made in the moment of play allow a run to score in exchange for other strategic purposes, but intentionally walking in a run is clearly in a different class of strategic maneuver. This may also have occurred when a pitcher was instructed to deliberately hit a batter with the bases loaded, but in this case, intention is not provable.
^Baseball Reference lists 6, but Hideki Okajima surrendered a home run on his first pitch April 2, 2007.
^ abThis is possible when a batter who has been struck out reaches first base safely under a dropped third strike. That is, if strike three is recorded on the batter but the catcher does not catch the ball to complete the putout (likely because of a wild pitch or passed ball) and first base is unoccupied, the batter may advance to first; the pitcher is credited with a strikeout, but no out is recorded.
^The Baseball Almanac states that 16 pitchers have accomplished this feat. Of these, all but Chuck Finley have only once struck out 4 batters in a single inning (consecutively or otherwise). Finley however did it 3 times, but the Baseball Almanac does not state how many of those were consecutive strikeouts (i.e., whether it was once, twice, or all 3 times).
^Some sources do not include the two perfect games thrown in the 19th century, because of differences in the rules of play, and thus list only twenty-one perfect games.
