I want to know the answer to the following question:
When did the Cubs announce a move of their top class A affiliate from Daytona to Myrtle Beach?
All the background I'm provided with is that "Two days later, on the 18th, the Cubs signed a 4-year player development contract with the South Bend Silver Hawks of the Midwest League, ending their brief relationship with the Kane County Cougars and shortly thereafter renaming the Silver Hawks the South Bend Cubs.". Is that enough to answer the question?
Answer: no
