Tsukishima mocks the two while Yamaguchi stands off to the side, smirking along. When Hinata asks about Tsukishima’s height, Yamaguchi answers for him, irritating Tsukishima.

Yamaguchi being consoled and advised by Makoto Shimada after Karasuno's loss at the Interhigh

During a timeout the players who were just on appear incredibly exhausted to Yamaguchi, but he claims to be jealous, and that he's sick of being the only first year who never gets to play. After being convinced by Sugawara and Ukai, Yamaguchi swaps with Hinata to attempt the jump float serve, with the intention of changing the match's momentum. However, he makes an error and the serve goes into the net. This upsets him incredibly as he leaves the court nearly in tears. 

Later, he talks with Makoto Shimada, his unofficial volleyball guide, about the match, who advises him about his choices in volleyball and reveals to him about his own experiences with volleyball. This motivates and determinates Yamaguchi to try harder in volleyball next time.
