The article didn't say anything about 'the Twins investigating Giants'. You make that sound like there is an official ongoing investigation when the article you linked said this: "The situation led to discussions between the Twins and Giants to determine what they knew about Dyson’s condition before the deal was made. The Twins have been unable to find any evidence that the Giants had knowledge of an injury. So Dyson and the Twins are bracing for surgery — and the possibility that Dyson, who’s arbitration-eligible for next season, won’t return to the mound until the middle of the 2020 season." So, how is this some major REPORT? It doesn't sound like there is anything more than they made inquiries and found nothing intentional on the Giants' part and are moving on.
