I like outdoor sports like baseball, tennis, and soccer.

Literal

I [topic-は] baseball [and-や] tennis [and-や] soccer [like-のような] outdoor sports [subject-が] like [is-だ].

や (non-exhaustive list) joins the sports examples. のような ('like, similar to,' the attributive form of ようだ) marks them as examples of a category (outdoor sports). 屋外 ('outdoor'). スポーツ is an English loanword.
