The opening weekend of the Monster Energy NASCAR Cup playoffs picked up a little spice at Chicagoland Speedway Friday when championship contenders Brad Keselowski and Kyle Busch engaged in some jousting on Twitter.
After four Toyota drivers, including Busch, who was fastest, led the first Cup practice, Keselowski, a Ford driver, tweeted, “We are all in for a rude awakening. Haven’t seen NASCAR let a manufacturer get this far ahead since the 70s.”
A few minutes later, Busch responded with a “crying” emoji and this: STFU.
Then Keselowski replied: “It’s 2017. When you’re about to lose an argument you call people names rather than face facts.”
In the practice session, Busch ran 184.143 mph. Keselowski was 10th at 181.574.
