Depends on what type/brand of bat/glove you want.
You need a glove, a bat, and bases.
a bat a helmet a glove and a ball
A ball a bat and a glove
You need the basic stuff for baseball. I suggest the you get a bat, a baseball, and a glove.
I guess they are more heavier than softball bats
Yes, the batter is credited with an at-bat and scored as a fielders choice.
A rotational hitter will hit a baseball harder with a heavier bat. This is because if they have enough bat speed, it will have a greater force pushing the baseball the other way.
If you are talking bout yourself, then a bat, batting gloves, a glove oh, and a baseball.
