After seeing Federer escape Kohli and eventually winning Halle, and Nadal escaping Verdasco and eventually winning Hamburg, it seems odd that the biggest threats some players experience are the 1st Round matches. Dangerous unseeded players do pose a big threat, while top players could be cold yet and is still revving up. What other examples of dangerous first round escapes that eventually proved good as they won the title eventually? If they didn't win the title which ones are examples who at least reached deep (i.e. Semis or Finals)?
