One of the most often overlooked factors for why a major league club is successful is the success of their minor league affiliates. While it’s not true for every team, it generally is more often than not. Baseball America noted that the three winningest major league teams of the 2010s, the Dodgers, Yankees, and Cardinals, have the third, second, and sixth highest minor league winning percentage respectively.
Conversely the farm systems of the Marlins, Padres, and White Sox, the least successful teams this decade, had the 22nd, 20th, and 24th ranked minor league winning percentages.
The Dodgers have consistently had one of the strongest farm systems for most of the decade, boasting and developing promising young talent such as Cody Bellinger, Gavin Lux, Corey Seager, Dustin May, and Walker Buehler. Their minor league affiliates have been so successful in fact, that two franchises, the Rancho Cucamonga Quakes (Single-A) and Ogden Raptors (Rookie-level) were ranked as top 15 minor league teams of the decade by Baseball America.
Rancho ranked as number 14 on the list. According to Baseball America, the Quakes were the most successful California League team of the 2010s. They have gone 758-640 over the past 10 seasons, capturing California League championships in 2015 and 2018. The Quakes started the decade as affiliates of the Angels, however they have been affiliated with the Dodgers since the 2011 season.
I'm pretty sure the only team that can claim both Cody Bellinger and Mike Trout is the Single-A Rancho Cucamonga Quakes. They'll be giving away a Bellinger/Trout "double MVP bobblehead" at a 2020 home game (date TBA).

The Rookie-level Ogden Raptors came in at number 15. Their 430 wins over the last 10 seasons ties for the most wins by a short-season team this decade. They have played for the Pioneer League championship five times (2010, 2011, 2012, 2017, and 2019), although their only championship win came in 2017. Baseball America noted that the 2012 Raptors team was particularly impactful, as they had both Corey Seager and Ross Stripling, who would both go on to their careers with the major league Dodgers.
