I want to know the answer to the following question:
When did Sammy Sosa explode into pursuit of Roger Maris' home run record?
All the background I'm provided with is that "Sosa had his first of four multi-home run games that month on June 1, and went on to break Rudy York's record with 20 home runs in the month, a record that still stands.". Is that enough to answer the question?
Answer: no
