Career highlights and awards

Yuta Iwasada (岩貞 祐太, Iwasada Yuta, born September 5, 1991 in Kumamoto City, Kumamoto) is a Japanese professional baseball pitcher who currently plays for the Hanshin Tigers of Nippon Professional Baseball.[1]


Early career[edit]

Yuta started his baseball career in 4th grade as an outfielder for the Wakaba Elementary School, and in 6th grade, made it to the semi-finals of a national baseball tournament.[2] He doubled as 1st-base infielder and pitcher for the Kumamoto Hitsuyukan Senior High but his team never made it to nationals.

He entered the Yokohama College of Commerce, and in his sophomore year, was chosen to pitch for the national team for the US-Japan Collegiate Baseball Championships. In his senior year, he was awarded Best Nine in the Kanagawa University Baseball League after winning 6 games in the tournament.[3][4]

Hanshin Tigers[edit]

He was the Tiger's 1st round 3rd alternative pick during the 2013 professional draft (after not winning the lottery for Daichi Ohsera and Yuta Kakita). He signed a 100 million yen contract with Hanshin plus a 50 million yen signing bonus, for an estimated annual salary of 15 million yen. He was assigned the jersey no. 17.[5]

In 2014, he joined the main squad for spring camp training in Okinawa, and started the practice game against the Eagles on Feb 19. After the game, he felt pain in his left ankle resulting from a torn ligament, and was consequently restrained from pitching further until he was fully healed.[6] He resumed pitching in the Western League farm games in July, and finally debuted in his first official start on the August 10 home game against the Carps in Kyocera Dome[7] where he gave up 4 runs in 4 innings. His first win came a week after in a match against the Baystars, where he allowed only two runs over 5⅓ innings.[8] He had four more starts after that, but unfortunately lost all of them. He finished the season with a 1–4 record, and an ERA of 4.60.

In 2015, during spring camp, he competed with fellow lefty Suguru Iwazaki from the same draft year for a spot in the pitching rotation, but in the end, Iwazaki prevailed.[9] Only when Iwazaki fell into a slump mid-season did Iwasada get a chance to make it to the lineup. He started the May 24 match against the Baystars, but pitched poorly and promptly lost the match. He made up for it in his next start against the Marines during the interleague, where he pitched 7 scoreless innings and earned his first and only win for the season, and his first ever victory in Koshien.[10]

During off-season, he was selected to pitch for the national team in the Winter League games in Taiwan. After pitching in 5 games, he received the league's Most Valuable Pitcher award after a 2–0 record and an astounding ERA of 0.53.[11]

He selected 2018 NPB All-Star game [jp].[12]

Playing Style[edit]

Pitch Distribution for Yuta Iwasada

He throws a four-seam fastball as his main pitch (max velocity of 148 km/h), and alternates with a cutter in the mid 130s, a slider in 120s and a change-up with a wide velocity range. Also included in his arsenal are a shuuto, a slow curveball in the low 110s, and occasionally a fork ball.[4][13][14]

In 2016, Tigers ace Atsushi Nohmi started teaching him how to master his specialty pitch, the forkball, as well as tips on how to control his changeup better.[15]
