Best challenge record in baseball (Stephenson, 83-37) is worth about zero runs once you count the umpire misses never challenged

Payroll tracks talent even more closely over longer stretches: .41 for one season, .51 averaged over 3 years, .56 over 5 (1997-2026).

Check a multi-year sample as a simple proxy for a competence.

Seeing a lot of salary cap charts using raw dollars and W-L. Compare each team’s payroll to that year’s median, and talent (BaseRuns) instead of record: the correlation is .42. Last year’s record vs this year’s: .55. 29 of 31 champions (1995-2025) had an above-median payroll.

The top is back to mid-2010s levels: 2.31x the league median in 2014, 2.06x now. The bottom five fell from 0.71x to 0.49x. MLB’s $171M floor would lift them to 0.81x. 12 teams are under it, including every team still playing.

Talent beyond payroll gets a team to October far more often than money alone (38% vs 12%), but titles mostly go to teams with both. Notice anything about the top four teams on this chart?

How playoff catchers stack up on ABS challenges vs. an average playoff catcher Hicks (TB) +0.22 runs, 3-2 Contreras (MIL) +0.06, 7-7 Bailey (CLE) +0.01, 4-7 Hedges (CLE) −0.39, 2-0 Smith (LAD) −0.48, 2-2 Above the line = better than average

Pitchers went 71-108 on challenges in the regular season. In October they're 1-0

MIL and LAD spread their challenges across hitters and catchers. TB and CLE conserve them for their catchers.

With Tango’s newer method, a lost challenge costs less as the game goes on. On average, a 3-0 challenge only has to be right 1 in 4 times early, 1 in 8 by the 7th, 1 in 20 in the 9th. About half of these calls were wrong. Hitters challenged about 6% of them.

Across every count, 3-0 is the 5th most valuable call for a hitter to challenge, and the least challenged.

A 3-0 challenge isn’t that bad. On average, a missed call at 3-0 is worth as much as 0-2. Hitters challenge it almost 6x less. It’s a terminal count, just like 0-2. Would you let a hitter back into a count up 0-2 or get a K? “Worst case you’re 3-1” is the pitcher’s best case.

Catchers challenge 0-2 almost 5x as often as hitters do at 3-0. Even when the ump misses by more than an inch, hitters at 3-0 challenge just 13% of the time.

From purely a fan perspective, the AFL rules seem good. A rough model projects fewer singles and more extra-base hits. Hitters are rewarded for hard contact. Fielders are forced to field. What am I missing?

Bloops vs hard contact (now / rule with leeway / as photographed): Bloops (<90 mph, landing 150–270 ft), hit rate: .626 / .488 / .420 Hard air contact (95+ mph), extra-base rate: .209 / .293 / .363 Barrels that stay in the park, hit rate: .420 / .580 / .750
