The Blue Jays are conducting an internal investigation after six minor league prospects all tested positive for PEDs within the last week, Sportsnet.ca’s Shi Davidi reports. Thirteen Jays prospects have now been hit with PED test-related violations within the last two years, a stunning increase for an organization that saw just 18 players fail tests from 2005-15. “This situation is very disappointing and disturbing to the organization; disappointing that the players made these choices, but more so disturbing that some failure of our environment allowed this to happen,” Jays GM Ross Atkins said. “It is our responsibility to create an environment and culture where our players know that PED use is not condoned, and to give them resources and education to ensure that they do not make these decisions.”
