Yoshinobu Yamamoto talks with MLB teams set to start, source says

The negotiating window for major league teams to attempt to acquire Japanese star pitcher Yoshinobu Yamamoto is expected to start Tuesday, a source told ESPN's Buster Olney on Friday.

Yamamoto is expected to be posted Monday, the source said, and the 45-day process for MLB teams to negotiate with Yamamoto will begin the following day.

Yamamoto, 25, is expected to be a top target for MLB teams after starring on the mound for the Orix Buffaloes since 2017, with a 70-29 record in Japanese baseball. His trademark is his wide assortment of breaking pitches, excellent command and a fastball in the mid-90s.

He was 16-6 with a 1.21 ERA and 169 strikeouts in 164 innings in 2023. Yamamoto pitched two games during the Japan Series -- the World Series equivalent for Japanese baseball. He allowed seven earned runs in Game 1 but came back in Game 6 and struck out a series-record 14.
