Touche!
Kyle is almost adopting a fencing pose as he moves forward with his right foot to return serve. Kyle remains balanced and poised even when stretching forward to deal with this good short serve. Notice how his free arm has moved backwards as Kyle turns his shoulders to increase his reach, and how his right foot is well forward, allowing Kyle to push back to his ready position without overbalancing.
