Rays, Yankees, Red Sox, Royals Top MiLB Org Standings

Three months into the 2021 minor league season, a look at how Major League Baseball teams’ minor league clubs are faring seems to have a clear American League East slant.

The top team as far as overall full season MiLB winning percentage is the Rays. Right behind them are the Yankees, followed by the Red Sox, who are tied with the Royals for third.

Those three AL East teams have a total of 12 full-season clubs. All 12 of those clubs are above .500 right now.

The Rays actually have the two winningest teams in all of the full-season minor leagues. The Rays High-A Bowling Green affiliate has the best record in the minors (56-23, .709 winning percentage). The Rays Low-A Charleston affiliate has the next best record (54-23, .701 winning percentage).

Here’s a look at the 15 winningest teams in the minors as of Aug. 4.

We did want to add one additional piece of context to our look at minor league organization standings. One thing you often hear from farm directors is how their teams are younger than the competition. It’s true that a younger team may struggle against older opponents, even if they have more long-term potential. So we looked at the average age of rosters (as of Aug. 4) across each organization’s four full-season teams. The average age of a full-season minor leaguer is currently 24.4 years of age. So the teams that are winning with younger than average players are in the top left quadrant of this chart. Those that are losing with older than average players are in the bottom right quadrant.

Here’s a look at the average age of full-season rosters as of Aug. 4.
