Yes. It affected him, even if only a little. Yukimura scans the court for an opening. Sanada at the net is making that difficult; his range doesn't leave space for a passing shot. In that case, Yukimura lobs high to the baseline behind him, the furthest point away from both Sanada and Aya.

Aya puts forth a dash of speed and manages to return it, but it hits her racket just slightly askew from the scramble, and flies high over the net.

Yukimura, already in place, leaps up and smashes it to the corner Aya just vacated. She managed to cover the distance with the slower speed of a lob, but there's no hope of her reaching this one.

From the sideline, where he watches with his arms casually folded, Marui's brow furrows in confusion. That... should've been Flayn's ball, right? Why didn't she go for it?
