Caitlin Clark's fiery temper flared up once more during the Fever vs. Storm game Thursday night ... when she got so mad at Victoria Vivians, she actually got all up in the WNBA star's face on the court.
The incident happened in the second quarter of the sell-out contest at the Gainbridge Fieldhouse ... when Clark banked in a 30-plus footer, despite Vivians' hand in her face.
After the long 3-pointer, Clark had a few words for Vivians ... which clearly ticked off the Storm guard.
