As we enter the final month of the regular season, Marc Delucchi makes one final update to his San Francisco Giants top prospect rankings.

It’s time to unveil the No. 20 to No. 11 prospects in the San Francisco Giants farm system in our final top 30 prospects update.

If you missed the honorable mentions and No. 30 to No. 21 prospects, you can check those out here.

The 2019 season doesn’t appear likely to end with the San Francisco Giants in the playoffs, but it’s still been a successful year.

When Farhan Zaidi was hired as president of baseball operations last offseason, the organization appeared to be in dire straights. The Giants roster was filled with aging players with bloated contracts, and the minor league ranks boasted one of the worst farm systems in baseball.

While the offseason brought momentary hope when the Giants became finalists for Bryce Harper, they entered spring training with mostly the same roster. However, as the season went on, outside additions like Alex Dickerson, Mike Yastrzemski, and Kevin Pillar began to make an impact.

By the end of July, they looked like a legitimate contender. The trade deadline was no longer an everything must go extravaganza and the new regime keenly balanced buying and selling on the trade market.

At the same time, a number of top prospects had career years, slowly increasing the reputation of the San Francisco Giants farm system. Now, the Giants system ranks among the middle of the pack and it looks primed to join the league’s elite very soon.

With every minor league affiliate’s regular season complete, now is a good time to take one final inventory of the best prospects in the organization.

Prospects are grouped by their grades on the scouting 20-80 grade scale. For those not familiar with the scale, check out this primer. Here’s a quick rundown for reference:

80: Top 5 player in baseball (8+ WAR per season at peak)
70: Top 10 player in the baseball (5-8 WAR)
60: All-Star (3.5-5 WAR)
55: Above-average everyday player (2.5-3.5 WAR)
50: Everyday player (1.5-2.5 WAR)
45: Platoon player (0.5-1.5 WAR)
40: MLB backup (0.2-0.5 WAR)
35: Quad-A player (0-0.2 WAR)
30: Triple-A player
20: Organizational player

Two important notes:

1. The grades next to the players are current expected values, meaning you can think of those grades as the 50% outcome. Obviously, most prospects have a wide range of potential outcomes so those grades are an attempt to quantify the average expected outcome.

2. Some players will have grades with + signs next to them (40+, 45+, etc.). This has to do with the way player grades work. Probably 60-80% of top 30 prospects in each organization fall somewhere from the 40-50 grades. So it can get difficult to differentiate prospect No. 11 from No. 23. Part of this is on purpose, but some 40-grade players are closer to moving up to a 45-grade than others. Hence, the plus. A strong second-half from a 45+ player will almost definitely jump them up to a 50 grade. Same with a 40+ player going to 45. You get the idea.

With that out of the way, let’s kick things off with a few honorable mentions, before taking a closer look at the No. 21-30 prospects in the San Francisco Giants farm system.

Note: These rankings were last updated following the trade deadline, and that list can be found here.
