The Hanshin Tigers told the media on December 9 that they received a list of unprotected players from the Yokohama Bay Stars. The two teams announced today that the Tigers selected twenty-two-year-old Yuya Onaka as part of their compensation package for losing Yamato to the Bay Stars via free agency.
Yokohama selected Onaka in the sixth round of the 2016 draft out of Hiroshima Keizai University. He pitched in eleven Ichi-gun games this season, all in relief, and allowed sixteen runs (fourteen earned) over 19.1 innings of work. He went 1-1 with a 6.52 ERA and 1.91 WHIP.
[UPDATE 12/18 @ 9:55pm]
The Tigers held a press conference for Onaka today. He was assigned the uniform number 27.
