Scrapy Run Multiple Spiders in a Single Script Asynchronously

I have a single python file and two spiders inside. I want to run a spider and wait to get the results from it, then run the second spider in my code. I have reviewed the Scrapy docs and couldn't find the solution. There is a way you can run multiple spiders in your code simultaneously but I don't want it. I need to have the return value from the first spider to run the second. I'd be really appreciated it if you have any ideas or suggestions.
