With the Major League Baseball season delayed, Masahiro Tanaka has returned to Japan amid concerns about the coronavirus in the United States.

Tanaka, 31, shared his reasoning on Twitter.

"Even after the suspension of the camp, while living in the campground Florida, there was an event that made me feel danger besides the infection with the new coronavirus, so I decided to return home with due care," the New York Yankees pitcher wrote. "We are currently waiting at home for two weeks, as requested by the Japanese government.

"I would like to continue to take responsible actions as an immigrant from abroad."
