I want to know the answer to the following question:
Who was acquired from the Oakland Athletics in early July?
All the background I'm provided with is that "On September 14, in a game moved to Miller Park due to Hurricane Ike, Zambrano pitched a no-hitter against the Astros, and six days later the team clinched by beating St. Louis at Wrigley.". Is that enough to answer the question?
Answer: no
