Other than softball, which was created as an offshoot, the sport most often compared to baseball is typically cricket. They’re both bat-and-ball sports that involve hitting, throwing, catching, fielding, and running to “bases” to score runs. There are definitely differences in techniques in batting and pitching/bowling (as it’s called in cricket), but the comparisons are understandable.
Over the years, there have been plenty of attempts to see if a player could cross over from one sport to the other. The Jon Hamm-led movie “Million Dollar Arm” was based on a true story about a reality show that wanted to see if Indian cricketers could make it in baseball.
