Hi, Matt.
If the wide part of the saddle is the correct width, then don't exchange the saddle. It does sound like it's possible you're position on the bike is too stretched out.
With the saddle level, try moving it forward on the rails a little. You want to make these adjustments a little bit at a time and then ride. If you move the saddle forward, you want to watch out for stress on the knees; also, fore/aft adjustments usually mean you also need to make height adjustments to keep the knees extension constant.
Can you ride comfortably on the saddle if you keep your hands only on the tops of the bars? That might tell you something about whether the reach is too long.
If the problem is extreme, a shorter stem might be the answer, or one with more rise.
Were you given a professional fitting session when you bought this bike? You should have been, with a good road bike like this. You might want to discuss this with your fitter, as well. Sometimes road bike shops tend to prosition riders with the bars too low and the position too stretched out, like a racer, when it's not really appropriate for the rider. Proper fit is part of the package when you buy an expensive road bike, or should be.
