MLB Commissioner Rob Manfred announced on Friday that Tatis has been suspended 80 games without pay after testing positive for Clostebol, an illegal substance under MLB's Joint Drug Prevention and Treatment Program.
The suspension is effective immediately.
"We were surprised and extremely disappointed to learn today that Fernando Tatis Jr. tested positive for a performance-enhancing substance in violation of Major League Baseball's Joint Prevention and Treatment Program and subsequently received an 80-game suspension without pay," the Padres said in a statement to MLB Network's Mark Feinsand. "We fully support the Program and are hopeful Fernando will learn from this experience."
The news of Tatis' suspension comes as Juan Soto returns to Washington for the first time since being traded from the Nationals to the Padres earlier this month.
Tatis, who had surgery on his left wrist in March and has yet to play in 2022, signed a $340 million, 14-year contract before the 2021 season.
