The San Francisco Giants have already called up a lot of their top prospects this season, and I don’t expect any more to make their debut in 2018. There really isn’t a point to call anyone else up right now with so many young guys already on the roster who need to get playing time.
Chris Shaw and Tyler Beede were the Giants top two prospects at the end of the 2017 season, and both made their major league debuts in 2018.
Austin Slater, Steven Duggar, Aramis Garcia, and Andrew Suarez were also in the top 10 last year and have since been called up to the big leagues.
