Roki Sasaki

While many highly-regarded prospects get some final polishing in the minors, the first rookie power rankings of the year feature Roki Sasaki, Dylan Crews and the top young talents getting a big-league chance.

It sure looks as if another impressive group of prospects could have a major impact on the majors this year. Baseball s next big star could be part of this year s rookie class.

Also, can Yoshinobu Yamamoto contend for the Cy Young? And when will we see Shohei Ohtani on the mound?

Behind "superhero" Shohei Ohtani, a gem from Yoshinobu Yamamoto and flashes of stardom from Roki Sasaki, the Dodgers' Japanese-born standouts put on a show against the Cubs in Tokyo.

Shohei Ohtani hit a solo homer in his return to the Tokyo Dome, Roki Sasaki threw three eventful innings in his big-league debut and the Dodgers beat the Cubs to sweep the two-game series in Japan.
