Cleveland's Trevor Bauer and Houston's Lance McCullers may be the two opposing pitchers that Royals fans dislike the most.
But what if I told you those two were feuding?
The two had a back-and-forth on Twitter that started Tuesday when someone wondered about the increased spin rate of some of the Houston pitchers, specifically Gerrit Cole and Justin Verlander, who both have been with the Astros for less than a year.
Bauer responded: "If only there was just a really quick way to increase spin rate. Like what if you could trade for a player knowing that you could bump his spin rate a couple hundred rpm overnight...imagine the steals you could get on the trade market! If only that existed..."
Bauer said his beef is with Major League Baseball, and it apparently dates back to the 2016 playoffs when he sliced his hand while working on a drone.
Bauer was asked if he prefer that the current rules be followed or if he'd rather they changed to allow for ball doctoring.
His response: "Just pick one But to not let me use non sticky surgical grade glue to reinforce the stitches on the back side of my pinky finger that has no chance to touch the ball while simultaneously allowing people to blatantly use sticky stuff is hypocritical to the max"
Astros pitcher Lance McCullers tweeted at Bauer: "Jealousy isn’t a good look on you my man. You have great stuff and have worked hard for it, like the rest of us, no need for this. I will ask though because my spin rate and spin axis on my 4 seem is a$$."
Bauer responded: "Not jealous my friend. Promise you that. I respect what you all are doing over there. My gripe is with the hypocrisy of @mlb for selectively enforcing rules when it suits them"
Bauer was being asked by Twitter users for evidence and he offered up this: "Spin rate increases about 350 rpm on average in our tests when using pine tar vs no pine tar. That was at 70ish mph. The effect is slightly less pronounced at higher mph, but still between 2 and 3 hundreds rpm increase at about 90mph"
Bauer then added: "Best way to spin a ball is apply force tangential to the ball. In baseball much of the force is applied through the center of mass to generate linear velocity. Entirely possible that pine tar allows the fingers to get closer to tangential -> more spin"
In case you wondered, adding pine tar to a ball is illegal.
Astros manager A.J. Hinch was on MLB Radio and said: "I don't know if it's gamesmanship, or college pranks, or what would make someone have any sort of statement that's without any evidence or anything like that, so it's kind of ridiculous that it's even a topic."
Hinch added that Cole's spin rate could have increased by throwing more four-seam fastballs and by working with pitching coach Brent Strom on other aspects of his game.
