Regarding pitcher Koyo Aoyagi, who is aiming to transfer to the majors from Hanshin using the posting system, MLB Network reporter Jon Morosi reported on his X on the 4th (5th Japan time), "The Hanshin Tigers have officially announced the posting procedures, and a 45-day period of negotiations with MLB teams has begun."

In response to the reporter's post, the leading major league information site "Trade Rumors" published an article about Aoyagi. "Aoyagi turns 31 next week, and is expected to add depth to the pitching staff. Although he was a starter for the Tigers, sidearm pitchers are often used in the bullpen," the article wrote, suggesting that he is in demand not only as a starter, but also as a relief pitcher. The article described this season, in which he made 12 appearances in the first team and 11 in the second team, as "a lackluster season."

In an analysis of his pitching performance, he was quoted as having an ERA of 3.69 in 61 innings pitched in the first division, with a somewhat harsh assessment that "his strikeout rate relative to the number of batters faced was 13%, which was 10% lower than the MLB average. His walk rate was 7.8%, which showed decent control, but nothing extraordinary." He did not mention his consecutive titles for most wins, highest winning percentage, and best ERA in 2021 and 2022, but said, "His career results are slightly better, with an ERA of 3.08 and a strikeout rate of 17.1%. It's been a decent season for two years in a row."

Aoyagi's total record over nine years in the NPB is 154 starts, with 61 wins and 47 losses, and an ERA of 3.08. "Looking at the numbers, there is a possibility that he will remain on a minor league contract," the site said. Explaining the current posting system, the site also wrote, "It is highly likely that the contract will be for less than 25 million dollars (approximately 3.75 billion yen), in which case the transfer fee (to Hanshin) will be 20% of the total amount." The deadline for negotiations with major league teams is January 17th next year (US time).
