I would say SURESH cannot hit a winner like a player a full level above him. But not all tennis players are the same, are they? Some go on to better than 4.0 levels, while other's only reach low 3.5's. Some even get better, at least college level, but are still rec players because they don't make a living from hitting tennis balls. And some guys in the top 300 ATP Pro are not PROS, but guys trying to break into the PRO rankings. A pro makes all his money from tennis.
