Sixty of the 5,754 people in a study of Major League Baseball employees tested positive for coronavirus antibodies, a rate lower than what similar studies run in California found.

"I was expecting a larger number," said Dr. Jay Bhattacharya, a professor of medicine at Stanford University, who ran the study. "It shows the value of doing the science as opposed to guessing."

The results of the study, which was held in mid-April, revealed a prevalence of COVID-19 antibodies in the MLB employee population of 0.7% -- a number adjusted to reflect testing accuracy.

The survey showed that about 70% of those who tested positive for COVID-19 antibodies had been asymptomatic.

After volunteering to participate, MLB was chosen by Stanford to join the study, which will have no bearing on the league's ability to return to play. Twenty-six of the league's 30 teams agreed to participate.
