A trio of "Jeopardy!" contestants clearly needed to brush up on their sports knowledge prior to appearing on the game show Tuesday night ... 'cause they missed on some serious softballs, including one that simply asked them to identify NBA superstar Russell Westbrook.

In one of the first clues, host Ken Jennings asked the three which MLB team won the 2008 World Series.
