That baseball is based on English and Irish games such as cat, cricket, and rounders is difficult to dispute. On the other hand, baseball has many elements that are uniquely American. The earliest published author to muse on the origin of baseball, John Montgomery Ward, was suspicious of the often-parroted claim that rounders is the direct ancestor of baseball, as both were formalized in the same time period.

The only certain thing is that modern cricket is much older than modern baseball, and that cricket was very popular in colonial America and the early United States, fading only with the explosive popularity of New York baseball after the Civil War. There was also "wicket," a countrified form of cricket which retained the old-fashioned wide, low two-stump wicket, and in which the ball was rolled along the ground. Baseball also owes to cricket some adopted terminology, such as "out," "innings" and "umpires." " Wikipedia.
