Do any Giants prospects deserve an early extension?

Should the San Francisco Giants consider early extensions for any of their top prospects like Joey Bart, Heliot Ramos, and Logan Webb?
It was announced on Friday that the Seattle Mariners and 23-year-old prospect Evan White agreed to terms on a six-year, $24 million contract extension that included three club options. It’s a contract that could indirectly impact all 30 teams, including the San Francisco Giants.
Why is the extension such a big deal?
White, 23, hit .293/.350/.488 with 13 doubles, 18 home runs, 55 RBI and 61 runs scored in 400 plate appearances while spending the bulk of the season at Double-A.
He has three years of experience in the minors since going No. 17 overall in the 2017 draft and he has yet to make his MLB debut.

White, 23, spent last season at Double-A. No player at that level ever has received a long-term extension.
Though the argument can be made that the Mariners are taking a big risk locking someone up who does not have major league experience, the flip side is that the team can bypass the arbitration process and potentially save millions of dollars if the player develops as hoped.
Do the San Francisco Giants have anyone in their farm system that they should consider signing to a similar early extension?
Let’s explore some of the options.
