As you set up for your return, pick a target on the other side of the net and visualize what that return will look like. Note how Ana mixes up the placement of her returns: first, right at me; next, to my right; and lastly, to my left. Notice how the last cross-court return for a winner does not have to be hit into the far-side doubles alley. Note how the ball crosses the center of the net. It's an effective return because Ana "set it up" by hitting the previous one to my right.
