Editor’s Note: Corrected story to add that the Twins have had a winning overall record every year since 2014.
Once again, the Rays have the most successful farm system in baseball, as measured by on-field success. The Rays’ .576 winning percentage across all their MiLB affiliates was easily the best in baseball, topping the second-place Rockies by nearly 30 percentage points. The Rays also led the minors in run differential. They outscored their opponents by 572 runs.
Looking only at domestic leagues, the Rays advantage only widened. From the U.S. complex leagues through Triple-A, the Rays had a .604 overall winning percentage. There were only 17 teams among the 154 MiLB teams in the U.S. and Canada that topped a .600 winning percentage. The Rays had three of them.
Baseball America has tracked domestic US MiLB winning percentage for years. This is the fourth consecutive season in which the Rays have topped all 30 MLB teams in MiLB winning percentage for domestic leagues. Tampa Bay’s success at consistently winning minor league games is a notch above any other MLB team. From 2018-2022, the Rays have a winning percentage of .597. No other MLB team has managed to post a .597 overall winning percentage or better in any one of those four seasons. In other words, the average Rays MILB season over the past four years is better than the best season by any of the other 29 MLB teams.
On the other end of the spectrum, the Angels managed to halt a streak. With a .517 winning percentage this year, the Angels have posted their first overall winning record across the domestic minors in at least eight years. From 2014-2021, the Angels best winning percentage was .492 in 2017.
With the Angels climbing above .500, the Mets have the longest streak of not having a winning overall record across the domestic minors. The Mets last were above .500 in 2015. The Twins have also had a winning overall record every year since 2014.
The Rays’ Carolina League-champion Charleston RiverDogs led all full-season clubs with a .667 winning percentage (88-44). The Dominican Summer League’s Pirates Gold team topped all affiliated clubs with a .746 winning percentage (44-15). The Florida Complex League Rays led all domestic teams with a .709 winning percentage (39-16). Thanks to the longer Triple-A season, the Brewers’ Nashville Sounds led all MiLB clubs in wins with 91.
With Sept. 28 marking the end of the Triple-A regular season, and all other MiLB leagues having completed their playoffs, the Rays, Yankees and Giants all are tied for the most MiLB titles this year with two. The Triple-A playoffs give the Rays an opportunity to add a third title as Durham is facing Nashville for the International League title. The Yankees’ and Giants’ Triple-A teams’ seasons have finished.
Here is a look at how all 30 organizations lined up as far as overall MiLB record and run differential in 2022.
And here are the standings for all the domestic US leagues without the Dominican Summer League standings included.
The Dodgers had the most teams above .500. The Athletics are the lone team to not have any MiLB teams with a winning record. Las Vegas (71-79, .473) was the A’s most successful team in 2022.
