Top prospects thrive at all levels as big club stays aggressive with promotions
Thanks to graduating stars like Ronald Acuna Jr. and Ozzie Albies, the Braves emerged with their first NL East title in five years. While their Minor League teams posted a .457 winning percentage, the system is still loaded with scary arms like Mike Soroka, Touki Toussaint, Kyle Wright and Ian Anderson -- just to name a few. With nine prospects in MLB.com's top 100, this group that has plenty of staying power.
Chicago White Sox
Jimenez, Cease continue making big strides for rebuilding system
A torn UCL in Michael Kopech's right elbow might put a damper on Chicago's rebuild, but there's plenty to like all around the diamond. Eloy Jimenez has the makings of a generational talent, while Dylan Cease broke through on the mound with an incredible season between Winston-Salem and Birmingham. Seven teams within the system reached the postseason, cashing in with one title -- the Great Falls Voyagers in the Pioneer League.
Tampa Bay Rays
Franco, Lowe break through to lead Rays to Minors' best winning percentage
Even with Willy Adames and Jake Bauers graduating, the Rays continued to roll at seemingly every level -- finishing with the best organizational winning percentage at .604 and two championships (Bowling Green and Durham). At 17 years old, Wander Franco hit his way to Appalachian League MVP honors (.351 average), while Nate Lowe crushed his way through three levels with 27 homers and a .985 OPS.
Lewis, Kirilloff pack punch for upstart group that finishes with two titles
The one-two punch of Royce Lewis and Alex Kirilloff was incredible all season, serving as key cogs at the plate in the Midwest League and Florida State League. Although the big league club regressed in 2018, their system finished with a solid .529 winning percentage, three playoff squads and two championships -- Class A Advanced Fort Myers and Rookie-level Elizabethton.
Toronto Blue Jays
Guerrero's transcendent campaign puts charge back into Toronto's system
Toronto's .527 system winning percentage was only part of the story as baseball's top prospect, Vladimir Guerrero Jr., stole the show with a .381 average between Double-A and Triple-A. Aside from Guerrero, the Blue Jays boast four other players in the top 100 prospects -- Bo Bichette, Danny Jansen, Nate Pearson and Anthony Alford (not to mention breakout star Cavan Biggio -- as the team looks to reload for another run that could come sooner rather than later.
Parkinson, four postseason squads highlight resurgent farm system
The rebuilding process is not yet over in Philadelphia, but with plenty of talented players in the pipeline, there's hope that the team will turn the corner soon. Adam Haseley broke through at the dish (.300 average), and David Parkinson stepped onto the scene with the Minors' best ERA at 1.45. With a .539 overall winning percentage and four playoff teams, the Phillies remain on the right path to success.
San Diego Padres
Return of Paddack, addition of Mejia keep San Diego on right path
They might have finished last in an ultra-competitive NL West this year, but the prospect-laden Padres still look like they're on the cusp of something big. Though a thumb injury shut down a promising season for Fernando Tatis Jr. in July, San Diego still has plenty of talent to surround the shortstop. The addition of Francisco Mejia, along with the impressive return of Chris Paddack, keep the Padres among the elite in this category.
2017 World Champions keep on winning with titles in Buies Creek, Tri-City
The reigning World Champions are back in the postseason after another 100-plus win season, and their farm system looked no worse for the wear. Buies Creek and Tri-City claimed their league crowns as five teams reached the playoffs. Kyle Tucker put forth another stellar campaign with Triple-A Fresno, and Yordan Alvarez ascended onto the scene and joined him with the Grizzlies. Corbin Martin and Josh James locked down solid pitching seasons to round out an impressive system that boasted a .562 winning percentage.
St. Louis Cardinals
Memphis rolls to another PCL title before taking Triple-A National Championship
Top prospect Alex Reyes looked poised to make his return to the mound, but a lat injury ended his season prematurely again. However, the Cardinals remained a fearsome bunch and rolled with a .550 winning percentage as Memphis took the Pacific Coast League and Triple-A National Championship. First-rounder Nolan Gorman mashed 17 homers in 63 games, while Dakota Hudson's 2.50 ERA in Triple-A earned him a spot in the big league bullpen down the stretch.
Los Angeles Dodgers
Another successful season culminates in three more league crowns
The Dodgers locked down another NL West title, but they weren't the only ones in the system celebrating. Double-A Tulsa, Class A Advanced Rancho Cucamonga and the Rookie-level Arizona League Dodgers all finished with a championship. Top prospect Alex Verdugo kept on hitting and earned himself some time in the Majors, while 20-year-old backstop Keibert Ruiz impressed in his first year in Double-A. Midseason trades made a small dent in their system, but the Dodgers still finished with a .549 winning percentage.
