Kodai Senga will be baseball’s best buy if he continues anywhere near the level he reached with the Mets this season as a major league rookie.

The Mets shouldn’t count on any such potential bargain if they pursue Japanese right-hander Yoshinobu Yamamoto, who is expected to be posted this offseason by the Orix Buffaloes.

A person connected to the front office of a team that may pursue Yamamoto indicated there’s a good chance the Yamamoto bidding will start somewhere in the $200 million range for six or seven years.

For context, Masahiro Tanaka’s seven-year deal worth $155 million with the Yankees, signed before the 2014 season, is the richest MLB contract received by a pitcher leaving Japan. Last winter, the Mets gave Senga a five-year contract worth $75 million that contains an opt-out after the 2025 season.
