Manager Ryne Sandberg spoke to general manager Ruben Amaro Jr. about the Cuban slugger this week.
"He thought he was interesting," Sandberg said. "He wasn't sure how things were going to work out ... but there was some interest there."
The bidding for Tomas could be intense. Some have speculated he could fetch more than $100 million, although if he produces like many think it could be a relative bargain, considering he is just 23.
"Another power bat, that would be very good," Sandberg said. "Four or five of them would be ideal."
