In what two sports can a "perfect game" occur?

The concept of a "perfect game" represents an incredibly rare pinnacle of athletic achievement, a contest where a player or team performs without a single mistake. In baseball, it is a legendary feat of pitching dominance and defensive flawlessness. To achieve it, a pitcher must face the minimum 27 batters over nine innings, retiring every single one without allowing any to reach first base. This is even rarer than a no-hitter, as it means there were no hits, no walks, no hit batters, and not a single defensive error. The immense difficulty is proven by the fact that only a few dozen have ever been recorded in the long history of Major League Baseball.

While baseball’s version requires a total team effort, the other officially recognized perfect game is a feat of individual precision in bowling. A perfect game on the lanes is a score of 300, achieved by bowling 12 consecutive strikes. This requires a bowler to get a strike in each of the first nine frames, and then three more in the tenth and final frame. Though far more common than a perfect game in baseball, a 300 is a celebrated milestone for any bowler, demanding incredible consistency and focus. Both achievements, one collective and one individual, stand as a testament to undisputed mastery in sports.
