Daichi Osera

On October 10, 2018, he was selected at the 2018 MLB Japan All-Star Series.

In 2014, he started the February 22 exhibition game with the Tigers, and pitched 2 scoreless innings. He recorded his first official win on the April 2 game against the Swallows, and along with Allen Kuri, the Carps became the first Central League team to field two first-year rookies that recorded victories in their first career starts in the same season since Yomiuri in 1960 (Ritsuo Horimoto and Hiroaki Aoki). On May 1, he pitched his first complete game against the Hanshin Tigers at Koshien, allowing only eight hits and two walks, while striking out seven, beating fellow rookie Suguru Iwazaki. He extended his personal winning streak to five games on May 16 to become the sixth Hiroshima rookie to win five or more in a row, since Hiroshi Nagadomi won six straight starts in 1985. He also became the fourth pitcher in franchise history to win five or more games before the end of May, and the only one of the four to record all five victories as a starter.

During the 2013 autumn draft, he was chosen as the first pick of three teams: Hiroshima Toyo Carp, Hanshin Tigers, and the Tokyo Yakult Swallows. Hiroshima won the draw and consequent bargaining rights. In November 16, he signed a 100 million yen contract with Hiroshima plus a 50 million yen signing bonus, for an estimated annual salary of 15 million yen. He was given the jersey no. 14.

In November, he became the winning pitcher during the second game of the 2013 Baseball Challenge vs Chinese Taipei held in Taiwan. His jersey was sold for 378,000 yen through a Samurai Japan Charity Auction, where proceeds were given to tsunami relief/reconstruction efforts in the Philippines via the Japan Red Cross Society.

In 2012, he again won the MVP and Best 9 awards, and his team championed again in Fukuoka League's summer and fall tournaments. Then finally, his wish for a rematch came true in June during the quarter-finals of the 61st Japan National Collegiate Baseball Championship. True to his word, he pitched a winning shut-out game, giving up only 3 hits, and delivered eight 151 km/h pitches. They were, however, defeated by Waseda University in the next leg. He was elected as team captain in his senior year. In all his 57 league games, he went 38-5, with an ERA of 1.07.

He was also a member of the national team (Samurai Japan) for the 2012 Asian Baseball Championship Tournament, where Japan triumphed for the fifth consecutive time. He struck out 9 consecutive batters in 3 innings during the second leg match against Pakistan.

In 2011, their team won the Kyushu Tournament championships, but was defeated by Sōka University's Yasuhiro Ogawa in the second round of the Meiji Jingu Tournament, despite Ohsera having delivered 159 pitches in 9 innings and 10 KOs. Later on during the off-season, he was quoted saying he wanted to have a re-match with Ogawa, and that this defeat was his motivation for training harder.

In July 2011, he was selected to participate in the USA College Baseball Championships, where he wore the jersey no. 14 and participated in two games. He was again selected in 2012.

In the Autumn 2010 Fukuoka Big 6 Baseball Tournament, he obtained a 5-0 win-loss record and a 0.63 ERA, which contributed greatly to his team's championship. He was selected as one of the Best 9, and was given the league's Rookie Award. In his sophomore year, he was given the Most Valuable Player Award in the summer tournament, and Best 9 and MVP award again in the autumn. His team won the championship for both seasons.

After graduation, he chose to enter Kyushu Kyoritsu University instead of joining the 2009 draft, wanting to be under the guidance of Coach Sei Nakazato who was responsible for rearing notable NPB pitchers such as Nagisa Arakaki and Takahiro Mahara. He took up sports science, and was tasked to further develop his thin upper-body build. Within four years, he was assigned to do pilates workouts, then moved on to full-fledged weight training, making him gain an additional 14 kg.

He finished the season at 10-8 with a 4.05 ERA and 115 strikeouts in 26 appearances, and became the first rookie in franchise history to win ten or more games in their first year since Toshikazu Sawazaki won twelve in 1997.

Daichi Ohsera (大瀬良 大地 , Ōsera Daichi, born June 17, 1991 in Ōmura, Nagasaki) is a Nippon Professional Baseball pitcher for the Hiroshima Toyo Carp in Japan's Central League. He was the Carp's top pick in the 2013 autumn draft.
