Hokkaido Nippon Ham Fighters outfielder Haruki Nishikawa would like to move to the majors as early as the 2021 season, the 27-year-old said Wednesday.

Appearing at the Fighters' team office in Sapporo to sign his contract for next season, Nishikawa is entering the second year of a two-year deal that reportedly pays him ¥200 million ($1.8 million) a year. A move overseas a year from now would require the Fighters to either post him or release him.

The Fighters' second-round pick in Nippon Professional Baseball's 2010 amateur draft, Nishikawa has been a starter for the past six seasons. He will qualify to file for domestic free agency next season but indicated a move overseas via the posting system is also an option.
