Early Baseball Career
Yūsuke started playing softball in 1st grade as both a pitcher and infielder, and continued until junior high. He doubled as a pitcher and infielder for Tsukuba Shuei High, but his team never made it to the national tournaments in Koshien. He hit a total of 27 home runs in high school.
He entered Hakuoh University in Tochigi prefecture, and played solely as 3rd baseman as their team participated in the Kankoshin Student Baseball Federation League. In his 4th year, he batted an average of .417 and set a league record of 8 home runs in a single tournament. He was also awarded for the most runs batted in (20 RBI). In all of his 98 game appearances, he recorded 119 hits and 93 runs, including 16 homeruns.
He was the Tiger's 1st pick at the 2016 NPB Draft. He signed with Hanshin for a contract of 100 million yen, 50 million signing bonus for an estimated annual salary of 15 million. He inherited the jersey number 3, formerly worn by retired infielder Kentaro Sekimoto.
He joined the main squad spring camp training but struggled at the plate as he went hitless for 17 at-bats. Despite batting .333 in 9 appearances during the pre-season games,  he was sent back to the farms as there was a surplus of infielders in the main roster.
He spent the 1st half of the season playing in Western League (farm games), where until June, he averaged .232 and batted in 14 runs (1 HR). Finally on June 23, he was called to pinch hit against the Carps in Mazda Stadium. He ended the season with a .237 average, 7 home runs and 38 RBIs in 198 at bats. He also finished second in the Central League Rookie of the Year voting behind Chunichi Dragons shortstop Yota Kyoda.
