A couple of open and shut cases

I read Andre Agassi's Open and I liked it. However, there were a couple of errors.

1. On page 338: "... when a team of landscapers arrive." The subject is team, not landscapers, so arrive should be arrives.
2. On page 357: "Ladies and gentleman, I introduce you to the greatest person I have ever known." This error is more obvious than the previous one - gentleman should be gentlemen.
