Russia has been a popular destination for WNBA players like Brittney Griner over the past two decades because of the money they can make playing there in the winter.

With top players earning more than $1 million — nearly quadruple what they can make as a base salary in the WNBA — Griner, Breanna Stewart, Diana Taurasi, Sue Bird and Jonquel Jones have been willing to spend their offseason playing far from home. It’s tough for WNBA players to turn down that kind of money despite safety concerns and politics in some of the countries where they play.

The 31-year-old Griner, a seven-time All-Star for the Phoenix Mercury, has played in Russia since 2014. She was returning from a break for the FIBA Women’s Basketball World Cup qualifying tournaments when she was arrested at an airport near Moscow last month after Russian authorities said a search of her luggage revealed vape cartridges.

On Saturday, the State Department issued a “do not travel” advisory for Russia because of its invasion of Ukraine and urged all U.S. citizens to depart immediately, citing factors including “the potential for harassment against U.S. citizens by Russian government security officials” and “the Embassy’s limited ability to assist” Americans in Russia.
