Romney, who is running for Senate in Utah, was shown on camera calling out to Westbrook after the Oklahoma City star picked up his fourth foul of the game late in the first half. Romney held up four fingers toward Westbrook as he walked down the court.

The Senate candidate donned a custom-made Jazz jersey with his name on the back, which he wore over a button-down shirt.

The Jazz defeated the Thunder to take a 3-1 series lead in the opening round of the NBA playoffs.

Romney, who previously served as governor of Massachusetts and was the Republican presidential nominee in 2012, failed to secure the Utah Republican Party's nomination for Senate on Saturday, triggering a June primary.

In the final round of voting at the party's convention, state Rep. Mike Kennedy (R) won 50.88 percent of the vote, with Romney following with 49.12 percent. Because neither candidate secured 60 percent, the two will head to a June statewide Republican primary.
