Yasmani Tomas will work out for multiple clubs at the San Francisco Giants complex in Boca Chica on Sunday and the New York Yankees will be represented.
The 6-foot-1, 240-pound Cuban outfielder has been cleared by Major League Baseball to begin talking to clubs.
Industry sources believe the 23-year-old could command as much as $100 million.
The Boston Red Sox recently gave Cuban outfielder Rusney Castillo a seven-year, $72.5 million deal.
