Basic factual errors

Question

You need to check your facts. Federer won five US Opens, not four, as you say in your description of his match with Agassi. Also, in your supposed description of the Del Potro match at the French in 2009, you describe Federer's match with Tommy Haas, not Del Potro. You didn't even bother to check if your description of the contest matched the score line.
