The brown, sticky pine tar solution has made headlines for decades, and pitchers are usually at the center of the controversy. Hitters get to use it on their bats without much fuss. Pitchers, on the other hand, get ejected and suspended for it.
So why do pitchers reach for pine tar in the first place? Does it actually help them perform better, or is it just a grip crutch that gets guys in trouble?
I dug into the rules, the history, and the current MLB enforcement to answer that. I’ll also cover what pitchers are actually allowed to use on the mound, since there’s a legal option most fans forget about.
If you’re a pitcher, a coach, or just a fan trying to make sense of the “sticky stuff” headlines, this one’s for you.
What Exactly Is Pine Tar?
Pine tar comes from distilling pine wood, and it has a thick, honey-like consistency. Long before pitchers ever touched the stuff, it was used to waterproof ropes and seal wood.
Baseball players discovered it does something else really well: it makes anything you rub it on tacky. That’s why hitters started smearing it on their bat handles for a better grip, and it’s why pitchers eventually started experimenting with it too.
Why Do Pitchers Use It?
Grip is the whole reason. Pine tar is tacky enough that it helps a pitcher hold the ball firmly, even when his hands are sweaty or the weather is cold and dry.
A better grip means more control over the release, and for a lot of pitchers that translates to better spin on breaking balls and more consistent command. That’s the appeal: it’s cheap, it works fast, and it doesn’t require any special equipment.
Here’s the catch, though. Unlike rosin, which is legal, pine tar changes the surface of the baseball itself when a pitcher touches it. That’s the part that gets pitchers in trouble, and it’s the reason MLB treats grip aids for pitchers so differently than grip aids for hitters.
Is Pine Tar Legal for Pitchers? The Real Answer
No, it isn’t. This part trips a lot of fans up because pine tar is completely legal for hitters, so it feels inconsistent that pitchers can’t touch it.
Under MLB’s Official Baseball Rules (Rule 6.02(c), the modern renumbering of what used to be Rules 3.01 and 8.02), a pitcher cannot apply any foreign substance to the ball, and cannot have a foreign substance on his hand, glove, or uniform while he’s on the mound. Pine tar counts as a foreign substance. So does sunscreen mixed with rosin, and so does any other homemade sticky concoction.
The only grip aid pitchers are allowed to use is the rosin bag sitting behind the mound, applied dry to bare skin. That’s it. Combining rosin with anything else, including sunscreen or lotion, is against the rules too.
If an umpire checks a pitcher’s hand, glove, or hat and finds it “unquestionably sticky,” that’s treated as evidence of an illegal substance. The penalty is immediate ejection, plus an automatic suspension under MLB’s enforcement policy. There’s no warning first offense once a check comes back positive.
Does the “Cold Weather Exception” Actually Exist?
You’ll hear this one a lot: “pitchers are allowed to use pine tar when it’s cold out.” I want to be straight with you here, because I don’t want to repeat a myth just because it’s popular.
There is no official cold-weather exception in the rulebook. The rule against foreign substances applies year-round, in every ballpark, at every temperature. What’s true is that pitchers have historically used pine tar in cold weather anyway, betting umpires would look the other way because a frozen baseball really is harder to grip. Michael Pineda did exactly that in an April game at Fenway Park, and he still got ejected and suspended for it once the pine tar on his neck showed up on camera.
So the honest version is this: cold weather is the reason pitchers are tempted to use pine tar, not a rule that makes it legal. If you’re coaching or playing and it’s freezing out, the rosin bag is still your only legal option.
Pine Tar for Pitchers vs. Pine Tar for Hitters
This is where the confusion usually comes from, so let’s separate the two clearly.
Hitters can apply pine tar to their bat handle, but only up to 18 inches from the knob. If a bat goes past that limit, the umpire pulls it from the game, but the batter isn’t called out or ejected over it. That’s why the George Brett ruling in 1983 was such a big deal. Brett’s home run was initially wiped out for a pine tar violation that far exceeded the limit, but the American League president overturned the call, ruling that the excess pine tar didn’t actually affect the outcome of the game.
Pitchers get none of that leniency. There’s no length limit to stay under, because pitchers aren’t allowed to use pine tar at all. Any amount found on a pitcher’s hand, glove, or cap is treated as a violation.
Notable Pine Tar Controversies
Two incidents come up constantly when this topic gets discussed.
The George Brett incident in 1983 is the most famous pine tar moment in baseball history, even though it was about a bat, not a pitcher. It’s still worth knowing because it’s what set the 18-inch standard everyone references today.
On the pitching side, Michael Pineda is the name most fans remember. In 2014, he was caught with pine tar visibly smeared on his neck during a game against the Red Sox, and HD cameras made it impossible to miss. He was ejected and handed a 10-game suspension. It’s the case most people point to when they say pitchers can’t get away with it anymore.
What Pitchers Can Legally Use Instead
If you’re a pitcher looking for a legal grip aid, the rosin bag is it. Applied dry to your hand, wrist, and forearm, it helps manage sweat and gives you a bit more tack without breaking any rules.
It’s not quite as sticky as pine tar, and I won’t pretend otherwise. But it’s legal, it’s available in every dugout, and it won’t get you ejected mid-game. If grip is a constant problem for you, focus on hand strength, ball feel during your bullpen sessions, and consistent rosin use rather than looking for a workaround.
Bottom Line: Is Using Pine Tar Cheating?
For a pitcher, yes. MLB’s rules are clear that pitchers can’t apply any foreign substance, including pine tar, to their hand, glove, or the ball itself. Hitters get a narrow exception for their bat handle, but that exception doesn’t extend to the mound.
With HD cameras and regular in-game hand checks now a normal part of the sport, pitchers who try to use it are far more likely to get caught than they were a generation ago. If you’re pitching at any level, stick to the rosin bag and build your grip the legal way. It’s a lot less risky than betting on an umpire not noticing.
