The Tampa Bay Rays worked out Cuban free agent Yoan Moncada at Tropicana Field this week.

It remains unlikely that they will sign the highly coveted 19-year-old prospect.

Moncada, a switch-hitting infielder, could receive a signing bonus between $30 million and $40 million, a high price for any club but particularly for the Rays.

"We try not to leave any stone unturned, and he's someone who has great intrigue and we're eager to see what he can do," Matt Silverman said on MLB Network Radio. "Given our financial situation, I wouldn't expect us to be the winners of an auction, but that doesn't mean we're not going to do our due diligence, make sure we evaluate the player and put our best foot forward.

"If we happen to be in a position to acquire him, great. But if not, we've done the work and know that we've checked the boxes."
