When to use who vs. which?
When sentence is correct? "teams which are pitching" or "teams who are pitching"
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

According to Grammarbook.com, "that" would be correct because you are introducing an essential clause (one that is necessary for understanding and not separated by commas) meaning you use "that" and "which."
Of course, if you use "that" earlier in the sentence, you can use which. But either way, because you are referring to a team, you do not use "who."

Which is used for aniamls and objects (e.g. The door which opened suddenly, made a creaking sound.)
Who is used for people (e.g. Mary who was hungry, went to the restaurant.)

Actually, now that I think about it, you can avoid the problem all together by saying "pitching teams" instead of "teams that are pitching."
It is a common translation problem.
