I see it as a real stretch to blame his problems on Covid. Every team's low-minors players missed a year because of Covid. That is no particular disadvantage for our guys. Yes, Garcia was overmatched in low-A ball as an eighteen-year old. That was a development gamble which the Phillies lost. Garcia did ok repeating low-A as a twenty-year old. Then his bat crashed this season. Perhaps the injury got him off to a bad start; perhaps he played injured all season. Were that the sense that the Phillies have, would they have tried to sneak him through waivers? A constant throughout his minor league career is a disturbingly high K-rate.
The low-minors Phillies 'prospect' legitimately most negatively impacted by Covid was Yhoswar Garcia, because he was a year older than normal for the high-bonus international guy due to his lying about age, and then losing another year because of MLB penalty, before he could be signed. So, already down 2 years, he lost a third to Covid and lost more time to injury this season. So, he is a Latin American player with only 202 AB after his age 20 season. Luis Garcia had over 1000 AB after his age 20 season.
