I watched this the other day:
2004 Davis Cup Roddick vs. Nadal
. At the time, Roddick was 22, and the #2 player in the world, and Nadal was an unknown 18-year-old. It was funny to see the commentators saying that Roddick was the favourite. The match was played in Spain, on clay. Although Nadal's serve was very poor at this stage, the results were very predictable.
