pc1, there's no way that Riggs' serve was EVER as big or as good as Budge's. Budge had a "great" serve. Riggs did not. At 59 years old, Budge's serve was bigger than Riggs serve ever was. Riggs had a very good, reliable, second serve. But, he never had much power in any aspect of his game. He was a slicer/dicer who won with mobility, variety and a lot of lobs and drop shots. He couldn't match the power of the big hitters and he knew it.
