Shortly after losing Game 7 of the Japan Series to the Hanshin Tigers, the Orix Buffaloes announced this morning that they have approved the posting of ace right-hander Yoshinobu Yamamoto to MLB.
As noted by MLB Network’s Jon Morosi, the next step in the process is the formal declaration of a posting window, which will last 45 days upon being announced. Morosi suggests that the announcement could occur in the coming days. Yamamoto has long been expected to enter MLB free agency via the posting system this offseason, though today’s news marks the first official confirmation from the Buffaloes that Yamamoto will be posted.
Yamamoto, 25, has established himself as the clear best pitcher in Japan in recent years. Since making his NPB debut as an 18-year-old in 2017, Yamamoto has posted a career ERA of just 1.72 with a 26.4% strikeout rate. Incredible as those career numbers are, Yamamoto has been even more impressive over the last three seasons: from 2021-23, Yamamoto has posted an eye-popping 1.42 ERA with a 27.4% strikeout rate against a walk rate of just 5.1% across 557 2/3 innings of work. His most recent performance saw him record 14 strikeouts while allowing one run on nine hits and zero walks in a complete game for the Buffaloes in Game 6 of the Japan Series.
Scouts have widely regarded Yamamoto as a starter with top-of-the-rotation potential in MLB. Prior to the 2023 season, scouts suggested to Joel Sherman of the New York Post that Yamamoto could be considered a “full grade” ahead of right-hander Kodai Senga, who landed with the Mets on a five-year, $75M pact last offseason in his first foray into stateside ball. Senga’s age-30 rookie season in MLB proved to be an excellent one, as he posted a 2.98 ERA and 3.63 FIP while striking out 202 batters in 166 1/3 innings of work. Needless to say, the idea of an ace nearly six years Senga’s junior widely regarded as the better pitcher of the two being available via free agency this offseason has to be nothing short of tantalizing for MLB clubs.
MLBTR contributor Dai Takegami Podziewski took a look at Yamamoto in the latest installment of his NPB Players To Watch series back in September, shortly after Yamamoto threw the second no-hitter of his career in front of several MLB scouts. Yamamoto’s unusual youth for a free agent and incredible upside figure to make him one of the most coveted free agents of the 2023-24 offseason.
In MLBTR’s most recent Free Agent Power Rankings back in August, we had Yamamoto as the third-ranked free agent to be on the board, behind only Shohei Ohtani and Cody Bellinger. The market for Yamamoto is expected to be among the most competitive of the offseason, with the Giants, Mets, and Cardinals among the reported suitors in addition to the Phillies, Cubs, Yankees, Red Sox, Rangers, Dodgers, Tigers, and Diamondbacks, all of whom he’s been publicly connected to on some level or other throughout his final season before moving stateside.
