There is no rule in Major League Baseball governing the acceptable tilt of a rookie’s cap, and there didn’t need to be until umpire Doug Eddings decided there was one, ejected St. Louis manager Oli Marmol for questioning it, and then admitted, on the record, that he had invented the whole thing.
The scene was Coors Field on Friday night, Cardinals up 4-1 on the Rockies in the sixth inning, and Hancel Rincón jogging in from the bullpen to make his major league debut. Rockies catcher Hunter Goodman, stepping in to hit, looked at Rincón’s cap and asked Eddings whether that was allowed: a hitter petitioning the home plate umpire for a ruling on the opposing pitcher’s headwear, mid at-bat, on the kid’s first night in the big leagues, and getting one.
Eddings called the hat “really, really crooked” and said nobody was going to wear one like that on his field, a patch of infield dirt he apparently believes comes with title and deed. He had the Cardinals’ catcher relay the correction to Rincón, who straightened it without a word of protest and went back to pitching.
A rookie fixed his hat. That should have been the whole story.
Umpires have always carried a certain landlord energy; they set the property lines of the strike zone, decide who’s trespassing on home plate, and everyone else just pays rent and keeps their mouth shut. But landlords usually need a lease to point to. Eddings needed nothing. He simply declared the premises his and started drafting code between pitches, and the Doug Eddings hat rule was born fully formed, with no committee, no memo, and no prior existence anywhere in the sport’s actual rulebook.
Except a few innings later, Marmol came out for a pitching change and asked Eddings, in front of everyone, what exactly gave him that authority. Eddings answered by tacking a pitch clock violation onto the Cardinals mid-argument and then ejecting Marmol outright, his fourth ejection of the season for anyone keeping a running tally on how often umpires eject him.
Marmol didn’t hide his opinion afterward. “Quite honestly, I thought it was pretty embarrassing on his end,” he told reporters after the game, which is a generous way of putting it. He kept going: “That’s just a power-hungry move, in my opinion,” he said, per Bleacher Report; somewhere between those two quotes, by his own account, he suggested Eddings grow the hell up, phrased with considerably more color in the moment.
Asked directly whether any of this was actually written down anywhere, Eddings gave the answer that turns institutional overreach into comedy: “It’s not [a rule],” he said. “I guess it’s a little unwritten rule.” That’s the entire Doug Eddings unwritten rule laid bare in one sentence: a standard he enforced, ejected a manager over, and then described using the exact language of a thing with no enforcement mechanism attached to it whatsoever.
Eddings tried to justify the standard by naming Dontrelle Willis, CC Sabathia, and Pedro Strop as pitchers who’d worn their hats more tilted than Rincón’s ever was, which undoes his own argument in real time; Sonny Gray still wears his hat crooked today and has pitched under Eddings without incident. Buster Olney flagged the same inconsistency:

So the standard bends for a veteran Eddings already knows and snaps tight for a rookie making his first appearance, which tells you this was never about the cap; it was about who had the standing in that moment to test it, and a debuting reliever had none.
Baseball’s rulebook covers balks, neighborhood plays, and the transfer rule in exhausting detail, and it still leaves enough gaps for an umpire to manufacture jurisdiction on a whim. Eddings found one of those gaps on a rookie’s first night in the majors and used it the way a landlord uses a lease clause nobody bothered to read closely enough to challenge; someone finally did, and got ejected for the trouble.
Baseball has spent this stretch run arguing about far bigger things, this year’s trade deadline chaos among them, and Eddings still found a way to make Friday night about a cap. That says more about the sport’s tolerance for improvised authority than it does about Hancel Rincón’s headwear.
The Cardinals won 7-6 anyway, on Iván Herrera’s go-ahead home run in the ninth, which had nothing to do with anyone’s hat and everything to do with actual baseball happening despite the umpire rather than because of him. Marmol’s ejection stands. Eddings’ office, self-appointed and freshly furnished, stands with it. For the rest of our MLB coverage, you’ll find plenty of chaos this season. None of it is quite this well-adjudicated.
