Since taking over the Diamondbacks in 2010, general manager Kevin Towers has aimed to turn his franchise into the rootinist, tootinist, unwritten rules followingest team in the land. He installed noted red-ass Kirk Gibson in the manager’s seat. He went on the radio  and claimed  that “it’s going to be an eye for an eye, and we’re going to protect one another,” adding that “ if you don’t follow suit or you don’t feel comfortable doing it, you probably don’t belong in a Diamondbacks uniform.”

Well, Randall Delgado belongs in a Diamondbacks uniform. And that’s not necessarily a good thing.

Delgado has barely earned his keep when it comes to good pitching (5.61 ERA over 34 games in relief), but he has to be in Towers’ good graces after Saturday night’s performance. The gap between pleasing one’s superiors and appropriate behavior is where the crux of this story lies.

It started on Friday, when Pirates closer Ernesto Frieri inadvertently hit Arizona’s Paul Goldschmidt on the hand. It was unquestionably a mistake—a fastball that sailed inside and barely clipped the batter, who flinched backward a hair too slowly. If D’Backs brass hadn’t decided to retaliate yet at that point, they probably gained clarity when the diagnosis came in: Goldschmidt’s hand was fractured and he’d miss significant time.

The Pirate to bear the retaliatory target was Andrew McCutchen—you hit our best player, we’ll hit yours—and Delgado drilled him in the ninth, after missing with his first offering (which came up and in, but not up and in enough), then sending a decoy breaking ball away. His third pitch, at 95 mph, hit McCutchen sqare in the spine. The outfielder gave no notice to the macho piece of Code saying that drilled batters should act like it didn’t hurt, instead going down as if he’d been shot. (A heater into the backbone will do that to a guy in ways that being drilled in the thigh will not.) On his way to first, he spiked his bat in anger. (Watch it here, including video of the leadup.)

For those who need further proof of intent, when Towers went on his radio diatribe last year, he specifically called out his team’s lack of response when Goldschmidt was hit: “Goldy gets dinged, and no retaliation. It’s like, ‘Wait a minute.’ If Goldy’s getting hit, it’s an eye for an eye. Somebody’s going down or somebody’s going to get jackknifed.” So there.

(Worth noting: Goldschmidt was hit three times in 2013, all without response, all with Wade Miley on the mound for Arizona. Was Miley talked to? To judge by his egregious use of force this spring, yes.)

After the game, McCutchen took issue less with the drilling itself than with its details. “Retaliation is going to happen in this game, but there is a right way to do it,” he said in an MLB.com report. “They had plenty of chances. First inning, do it. Perfect time: one out, guy on second base. Get it over with. But they wanted to wait it out, wait until the ninth, second and third.”

Indeed, Arizon had first base open with one out and McCutchen at bat in the first inning. It is a tailor-made circumstance for those with pain on their minds. Trouble is, Gibson had a similar situation in June—first base open against the Brewers—and when he used it to drill Ryan Braun, it ended up costing his team the game.

So he waited. Even if Arizona’s need to retaliate is highly questionable, the method of execution Gibson chose is not. The game was tied in every one of McCutchen’s preceding at-bats, when allowing a baserunner in the name of vendetta would not just be wrong, it would have been even stupider than what the D’Backs ended up doing.

Gibson’s act might have played well when he was starring for the Tigers in the 1980s, but the game has changed. That kind of response to a clearly benign situation is no longer acceptable. McCutchen gets huge credit for not charging the mound, but that’s a possibility—if now a downright likelihood, and not just with the Pirates—if Arizona pitchers continue their reckless ways.
