Naomasa Yokawa

When his performance began to improve in 2017, his teammates in the farm noticed his habit of pounding his chest with his palms after he hits a home run, and promptly gave him the nickname "Gorilla". By 2018, his teammates would do the "Gorilla Pose" ("Go-ri-ra Po-su" or ゴリラポーズ) after he hit one home run after another, both in the farm and main squad games. This eventually spread and even the main squad members now call him by this nickname, and greet him with this chest-slapping gesture as he returns to the dugout after a successful run.

Yokawa started playing baseball in 2nd grade as a third baseman for the East Sekime Lions (little league), then he doubled as a pitcher and infielder in junior high. He was converted to a shortstop upon entering Konkōōsaka High School, and experienced playing in the Spring Koshien in his third year. He hit a total of 36 home runs in his high school career.

Before the 2013 draft, he said that he would turn pro only if he was drafted in the 3rd round or earlier, but will play for the industrial leagues otherwise. The Tigers chose him as their 3rd pick, and he accepted their offer. He was assigned the jersey number 55.

He started the year with an impressive performance during the pre-season exhibition games and farm games. By April, he secured the cleanup position, topped the player rankings by hitting 0.347, and got awarded the MVP of the month for 2 consecutive months for scoring 18 RBIs (5 home runs). He got promoted to the main squad during the April 15 match against the Dragons, and recorded his first hit on his first at-bat during the top of the 7th inning. On April 29, his first career home run won the match against the Baystars, and he got to experience his first hero interview with pitcher and fellow 2013 draftee Yuta Iwasada. He then alternated as a 3rd baseman or left outfielder during his next appearances, though mostly as substitute for other starters, until he fell into a slump and was eventually sent back to the farm. While his performance in the main squad games was not the best, he redeemed himself in the minors where he got the triple crown title; he was the batting champion with an average of 0.301, RBI leader with 62 RBIs, and home run leader with 14 home runs (tied with another Softbank player). He also got awarded the 2016 Hanshin Farm MVP.

During the 2009 draft, the Yomiuri Giants chose him as their third pick for the ikusei draft (developmental draft), but he rejected their offer and opted to enroll in Tokyo University of Agriculture instead.

He spent his first year playing in minor league games. In his 98-game appearances, he batted 0.241, recorded 38 RBIs and 6 home runs. Although he alternated playing as 1st and 3rd baseman, he committed 12 errors when he played the latter.
