The top name that has come up in SF Giants trade rumors as of late is Bryce Eldridge. As the top prospect in the organization, he is the most valuable trade chip but the Giants have another prospect in Josuar Gonzalez who is valuable as well.
Gonzalez is the No. 2 prospect in the organization and is and 18-year-old shortstop from the Dominican Republic. He is seen as one of the top 100 prospects in major league baseball so he has a ton of upside even though there is a long way to go until he would be considered for the big leagues.
