Yusei Kikuchi (菊池 雄星,Kikuchi Yūsei;Japanese pronunciation:[ki̥kɯtɕijɯꜜːseː], born June 17, 1991) is a Japanese professionalbaseballpitcher for theLos Angeles Angels ofMajor League Baseball (MLB). He has previously played in MLB for theSeattle Mariners,Toronto Blue Jays, andHouston Astros, and inNippon Professional Baseball (NPB) for theSaitama Seibu Lions. Kikuchi has been named anAll-Star in 2021 and 2025.
Kikuchi attendedHanamaki Higashi High School, the same high school thattwo-way playerShohei Ohtani would later attend.[1] As a high school pitcher, Kikuchi had a fastball that was clocked at 154 km/h (96 mph) in 2009.[2][3] In October 2009, Kikuchi sparked controversy when it was announced that he was considering bypassing the amateur draft in Japan for the NPB and signing with an AmericanMajor League Baseball club. Under Major League Baseball's current rules, Kikuchi would not have been subject to the MLB Draft and instead be declared a free agent, free to sign with any American team he wanted.[4][5] TheTexas Rangers were one of several teams interested in signing Kikuchi,[6][7] as well as theBoston Red Sox.[8] Japanese news service reports also identified scouts from theLos Angeles Dodgers,Seattle Mariners,New York Mets,Cleveland Indians,Chicago Cubs,San Francisco Giants,[9]Detroit Tigers,Atlanta Braves andNew York Yankees watching Kikuchi in tournaments.[3] All 12 NPB teams were also reportedly interested in signing him.[8][10]
Hanamaki Higashi manager Hiroshi Sasaki submitted paperwork to the high school baseball federation inIwate Prefecture on Kikuchi's behalf, stating his desire to turn pro. The move opened the way for professional teams to make contact with Kikuchi in a race to secure his services. With the submission of the paperwork, Kikuchi was open to be named in the Japanese baseball draft, which began on October 29, 2009.[11] He was expected to be named as a No. 1 draft pick by several Japanese clubs.[2][4][12][13] NPB had asked that Kikuchi not receive an offer from any major league clubs before Japan's draft,[14][15] in order to even the chances for Japanese teams, who are not allowed to make offers before the draft.[8] Kikuchi helped Hanamaki Higashi to a runner-up finish at the national high school invitational in April and to the semifinals in the national championship in August.[5][16] Kikuchi had reportedly expressed a preference to play in the United States and even visited in October.[17]
Kikuchi would have been the first Japanese high school player to bypass the domestic amateur draft to come to MLB.[4][18] By staying, players lock themselves into nine seasons before they're eligible for free agency.[5] They can leave only if their Japanese team allows them to enter the posting system in which MLB teams can bid for the right to negotiate with them. Furthermore, leaving for an American team bans players from Japanese leagues for three years.[3][13] Kikuchi held talks with the Red Sox, Dodgers, Rangers, and Giants on Monday, October 19, and talks with the Yankees, Mets, and Mariners the following day.[8][19] He decided to stay in Japan and enter the draft instead of playing in the United States.[20]
