Baseball has only been on the official roster of Olympic events since 1992, because the "non-measurable" nature of baseball-the fact that any given pitch alone can't be judged as a winner or loser-made it essentially different from other Olympic events.
棒球運動一直到一九九二年才列入奧運正式比賽，原因就在於其「非量化」（如好、壞球的判定）因素比其他運動比賽來得關鍵。
