I want to know the answer to the following question:
Who announced on August 22nd they were leaving the Cubs prematurely?
All the background I'm provided with is that "Despite being well out of playoff contention the Cubs went 24–13 under Quade, the best record in baseball during that 37 game stretch, earning Quade to have the interim tag removed on October 19.". Is that enough to answer the question?
Answer: no
