What more fitting place than our nation’s capital for baseball’s latest incident involving high crimes and espionage, which we might as well call Pine Tar-gate right from the start because, well, somebody had to do it.

At one end of last night’s shenanigans was Rays reliever Joel Perralta, supplier of pine tar; at the other was Nationals manager Davey Johnson, who didn’t much care for the extra edge the substance may have afforded the opposing pitcher.

When Peralta came in to pitch the bottom of the eighth, Johnson asked plate ump Tim Tschida to check his glove. And with that, the right-hander was ejected before he even threw a pitch, for what Tschida later said was a “significant amount” of pine tar—a prelude to a likely 10-game suspension. On his way off the field, Peralta tipped his cap toward the visitors’ dugout, a sarcastic display that he later phrased in a Washington Post report as “Good for them.” (Watch it here.)

The moment held intrigue on several levels. One is the fact that the pitcher not only played for the Nationals, but absolutely blossomed for them, as well. At age 34, Peralta went from ERAs of 5.98 (with Kansas City in 2008) and 6.20 (with Colorado in ’09) to a splendid 2.02 mark for Washington in 2010. That season he led the team in WHIP, hits-allowed-per-nine-innings and strikeout-to-walk ratio.

We may now know the reason. Somebody in the Nationals organization obviously had inside information they were willing to share about Peralta’s extracurricular habits; on the coaching staff alone, Nationals bench coach Randy Knorr served as the team’s bullpen coach in 2010, and first base coach Trent Jewett managed Peralta in the minor leagues that same season.

Were either of these people—the Nationals insider who dropped a dime on Peralta, or the manager who was willing to exploit it—playing within the boundaries of the unwritten rules? The short answer is no, but comes with the caveat that Johnson clearly doesn’t care.

For proof of this, look no further than Game 3 of the 1988 National League Championship Series, when Johnson—then managing the Mets—asked the umps to check Dodgers reliever Jay Howell. Like Peralta 24 years later, pine tar was found on the laces of the right-hander’s glove. (Darryl Strawberry said that the extreme break on Howell’s pitches tipped Johnson off, but other sources fingered Mets minor league manager Tucker Ashford, who had played against Howell some years earlier.)

Unlike Tuesday’s game, that move appeared to be tactical; Johnson waited until Howell was trying to protect a 4-3, eighth-inning lead, with a full count on leadoff hitter Kevin McReynolds. Howell was summarily ejected, and his replacement, Alejandro Pena, quickly served up ball four, helping ignite a five-run Mets rally.

The Nationals organization also has a history with the topic. In 2005, then-manager Frank Robinson had umpires—oddly, Tschida was behind the plate in that game, as well—check Angels reliever Brendan Donnelly. He was tipped off by his outfielder, Jose Guillen, who had recently left Anaheim under acrimonious terms.

“There’s etiquette and there’s lack of etiquette,” said Donnely at the time, in a Washington Post report. Robinson’s behavior, he said, was “the latter.” Angels manager Mike Scioscia was furious, and threatened to “undress” Nationals pitchers in response. His reaction was not so far removed from that of Rays skipper Joe Maddon—who happened to be Scioscia’s bench coach at the time.

Maddon was peeved enough yesterday to order a retaliatory examination of his own; at the manager’s request, Tschida checked Washington pitcher Ryan Mattheus a half-inning after tossing Peralta, and found nothing amiss.

“Heads up,” Maddon sarcastically told reporters after the game, according to a MASN report, as he wiped his unblemished desktop with a paper towel. “The desk is a little sticky right there.”

His follow-up comments were pointed.

“Insider trading right there,” he said. “It’s bush. It’s bogus, man. That’s way too easy right there. If you had done some really good police work and noticed something, that’s different. But that’s way too easy. That was set up on a tee for them.”

Much of Madden’s disconcert concerns the substance in question. Pine tar is as benign a material as can be illegally found on a ballfield; it is so common that a bag of its powdered form, rosin, is kept atop every major league mound.

Unlike lubricants such as Vaseline or K-Y Jelly, which increase a pitch’s movement by decreasing friction as the ball rolls off a pitcher’s fingers—in effect, allowing it to squirt out rather than roll, with minimal backspin—pine tar adds tack. It’s primarily used by pitchers to get a feel for the ball on cold, wet nights, but—as may have been the case with Peralta, who was pitching in near-70-degree swelter—it can also add snap to a breaking ball.

Said 1997 AL Cy Young Award winner Jack McDowell: “The only [illegal substance] I ever saw was pine tar, and I guarantee 80 percent of the pitchers still use it.”

Apparently, Maddon agrees.

“You’re going to see brand new gloves throughout the major leagues, starting tomorrow—pitchers on every Major League ballclub,” he said after the game, suggesting that pitchers everywhere will be inspired by Tuesday’s events to lay low for a while.

“It’s kind of a common practice—people have done this for years,” he said. “To point one guy out because he had pitched here a couple of years ago, there was some common knowledge based on that. I thought it was cowardly. . . . It was kind of a (expletive) move. I like that word. (Expletive) move right there.”

Ultimately, Maddon is right: If Johnson wanted to play by the unwritten rules, he would either have ignored the pine tar on Peralta’s glove or handled the situation in a far less obvious manner. It’s a stretch to think that having the pitcher tossed even served to level the playing field, because it’s likely that both teams have one or more pitchers who search beyond the rulebook for a similar edge. (“Before you start throwing rocks,” said Maddon to Johnson, through the press, “understand where you live.”)

The standard bearer for Code-based reactions in this category is Tony La Russa, who, when confronted with the fact that Tigers pitcher Kenny Rogers clearly had a clump of pine tar on his left palm during the 2006 World Series, opted against having the pitcher checked—which would have almost certainly led to ejection and suspension—instead requesting only that the umpires make the pitcher wash his hands.

La Russa’s comment at the time: “I said, ‘I don’t like this stuff, let’s get it fixed. If it gets fixed, let’s play the game.’ . . . I detest any B.S. that gets in the way of competition.”

Johnson nailed his man on Tuesday, but it’s easy to feel like a touch too much of La Russa’s B.S. got in the way of Tampa Bay’s 5-4 victory. Then again, it is Washington D.C., a city whose political culture appears to have been built on the stuff.

Update (6-18): Johnson thinks Maddon is a “weird wuss.”

Update (6-20): Peralta got eight games.
