here is a nadal FH on a low ball with more than 45 degrees upward swing

and here are higher balls with a flatter swing (more like 25 degree I estimate)

and on chest high balls he will swing probably even flatter. swing trajectory has a Lot to do with strike height.
Subtle difference between the low and high balls...
