Given the success of our Latin American program (or lack thereof) in the past decade it is hard to say that our relationships in Venezuela have been a net positive. There are more Dominican than Venezuelan players in MLB (90 vs 53 in a 2022 count). The Phillies typically sign more Venezuelan prospects than Dominican prospects though (sometimes as much as a 2-1 ratio) and many of our high dollar signings (Yhoswar Garcia for instance) are Venezuelan.
It is hard to see any competitive advantage in that data. One might even posit that the Phillies are losing some Dominican signees because the organization is seen as Venezuelan biased (that is speculation, but when most of your mid-level signings are from one country that has a lesser record of producing major leaguers then one has to wonder).
