I was wondering if the expression “play spoilsport” is used by native speakers.
It is not used by this native speaker, or by any other native speaker he knows. Until I read your post, I don't think I had seen or heard that "expression" (if it can be called an expression) in my entire life.
"Spoilsport" -- whether spelled that way or as "spoil-sport" or "spoil sport" -- is not very common in American English. In the Corpus of Contemporary American English (COCA), which has over 560 million words, "spoilsport" appears 38 times.

a. We were all psyched about going out in the field and playing soccer, but the rain played spoilsport .
b. We were all psyched about going out in the field and playing soccer, but as soon as we went out to play, the rain became such a spoilsport.
No. To me, they do not sound natural at all.
grammarcrazed posted:If not, what expression do you guys recommend that is commonly used by native-English speakers.
You could say "the rain spoiled our plans."
