If you read the story, it explains that the umpires never saw anything on the balls that would suggest a substance was used.
He had some good stuff last night. The opposing team tried to throw him off his game. It didn't work.
Considering how long Kenny has been around, it is more likely he did it to throw the opposing batters off their game, worrying about the ball being tampered with. I think Rogers got in their heads.
This is from the ESPN news desk. Facts are FACTS. He is a cheat.
After the substance was noticed, ESPN reviewed tapes of Rogers' pitching performances earlier in the postseason. The tapes revealed that, in starts against both the Yankees and Athletics, a similar-looking brown substance was spotted on Rogers' hand.
I'm not sure how you came to the conclusion that the other team tried to throw him off his game. They purposely did not make an issue out it. He had something suspicious on his hand. If you watched the game, you know that. It didn't cause the Cardinals to loose but it was illegal in baseball.
