WORK AT, WORK IN, WORK FOR? These are not used as phrasal verb but are used in different contexts. For example:
He works at a Bank. ( a large woking place)
He works for M/s ABC company. ( He is contributing to the company hls labour/efforts)
He is presently woking in the garden. ( A small place)

Out of the three sentences I am not sure about the fist one. It can be correct.
Steve is in the baseball team, is correct.

I'm tired after a long trip.-better.
