Nippon Ham Fighters manager Shinjo Tsuyoshi voiced the need for institutional supplementation to enter the Major League through posting and then return to Japan immediately to transfer to another team. 

Japanese media Daily Sports said on the 20th, "Coach Nippon Ham Shinjo attended the meeting of coaches of 12 clubs held on the same day. In the discussion on the posting system, the issue of the transfer of Uwasa and Naoyuki to Softbank was raised." 안전놀이터

Usawa is a veteran right-handed pitcher who recorded 70 wins and 62 losses with an ERA of 3.19 in 173 games (1,118 ⅓ innings) in the Japanese pro baseball league. He successfully advanced to the Major League by signing a split contract with Tampa Bay last winter that includes invitation to spring training. However, he only lost one game (nine ⅔ innings) and had an ERA of 13.03 in four exhibition games, before being traded to Boston to start the season with Triple-A of the Minor League.

After staying in the Minor League for a while, Wausawa was called up to the Major League in May last year, but after two games (four innings) with a 2.25 ERA, he went back to the Minor League. Afterwards, he ended the season with a poor performance of 20 games (59 innings) with five wins, four losses and 7.63 ERA in the Minor League without a call-up in the Major League. At the end of the season, he had to end the season early due to injury.

Having failed in the U.S., Wausawa has decided to return to Japan. He moved to the Major League through posting, but signed a four-year contract worth 1 billion yen (or 9.3 billion won) with Softbank, not his original Nippon Ham team. Unlike the KBO League, where he has to return to his original team after entering the Major League through posting, the Japanese pro baseball can return to the team as an FA. The KBO League must play four more years after returning to the Major League to qualify as an FA. 

Shinjo, who seemed to lose his starting pitcher to a rival team in vain, said, "I hope the trend toward Softbank will stop as it has only been a year since I started posting." Wouldn't it be boring if Softbank becomes stronger? Wouldn't it be no fun? I don't think that's a good thing. That's why I said that." Shinjo, who is leading the Nippon Ham, pointed out that the posting system is actually being used as a means to neutralize the FA system. 

Asked what other managers' opinions were, Shinjo replied, "Wouldn't they not really touch on these issues? I just pointed out the bad part of the Japanese professional baseball regardless of what anyone says?" He added, "This trend is not good. Examples include Kohei Arihara (Softbank), Naoyuki Uwasa and others. If players like Aoyagi Koyo (Philadelphia), Shinnosuke Ogasawara (Chunichi), and Roki Sasaki (Dodgers) (who entered the Major League this offseason) get in trouble or are released due to lack of performance, (other clubs) will naturally want to recruit players. If that happens, it will eventually become the trend toward Softbank, which I hope will not do." 

"Shouldn't I play for at least a year (for my original team) when I come back from posting? I think at least a year is necessary," Shin said. "If I go abroad and come back after a year and go straight to another club, I can't help but wonder, 'What is this?'" Shin said, stressing the need to supplement the posting system.
