Sakata is from Kanagawa Prefecture. From Yokohama College High School through Hakodate College, I joined Seibu in 4th Draft in 2009.

When I hit eight home runs in 39 games in the second year, I played the most number of 71 matches I played the following year.

However, afterwards he was unfortunate to have a chance to participate in the shoulder injury and so on, so this season has not participated in the 1 army so far.

Seibu is also the 11th year Ryohei Fujiwara pitcher, Takuya Toyoda pitcher and Kentaro Fukuraki together for the fifth year, and Yukinobu Tamamura pitcher for the fourth year together with five people next season I announced that I will not sign a contract.
