I took this from an SFG tweet:
With Buster Posey opting out of the 2020 season the Giants catching corps will need reinforcements. It seems Chadwick Tromp is making some noise. Tromp is from Aruba, is 25, and has been in pro ball (Reds system) since he was 18 but has no ML time. The right-hander is considered a long shot but that calculation has changed since Posey's announcement. He was a non-roster invitee. Two other NRIs, Rob Brantly and Tyler Heineman, are favored to see the most innings in the early going.
