The Rakuten Eagles are thinking about using Okajima as an emergency back-up catcher in 2018. Okajima was drafted as a catcher in 2011 and started playing the outfield in 2013. His registered position was changed to outfielder in January 2014.
May 18 vs Softbank at Rakuten Seimei – Okajima recorded the fifth walk-off (including non-hits like sac flies, walks, and ground outs) of his career, first since May 3, 2016.
