During his seven seasons in the Nippon Professional Baseball, Yamamoto had a 1.82 ERA with 922 strikeouts over 897 innings. He was a three-time winner of the Eiji Sawamura Award, the Japanese equivalent of the Cy Young Award

“It wasn’t one specific thing, everything was so different, on the field and off the field,’’ Yamamoto said. “But I think I got myself acclimated.

“This is my second year, I’m not a rookie anymore. So I’d like to get better and be a player who can make a contribution to the team a lot more.

“I did feel some responsibility for losing the game, but over the course of the whole season, I learned a lot.”

Roberts, a Japanese native as well, is upbeat on what lies ahead for his right-hander.

“I think Yoshinobu has grown up considerably in one year, I really do,’’ Roberts said. “I think he’ll have a tremendous season.’’

Yamamoto, whose Dodgers’ jersey is second only to Ohtani’s that is being worn by Dodgers boosters in Japan, can push off from the harbor with a strong showing against the Cubs, where he’s not expected to exceed five innings.

“I see it as a lot of support from my fans and I like to turn it into positive energy and carry that to the mound,” Yamamoto said.

What’s certain is this baseball-crazy nation will focus on every pitch at the Tokyo Dome as two of its own look to shine.
