premise: One man is tackled by one opponent while trying to touch base. hypothesis: A man is tagging another man on a baseball field.
neutral: There are many sports which involve touching a base and a baseball field is only one of many possible locations where such an action can be performed. If a man is tackled by another opponent, it doesn't necessarily mean that tagging is the intention. The person tackling a man may be a woman and not necessarily another man.
