Doubles in Fed Cup by nature comes with a high degree of pressure: If the tie is deadlocked at 2-2, the doubles rubber—played as the last match—determines who moves on to the next round.
That being said, the 2018 opening weekend could see some intriguing match-ups.
The U.S., coming off its first championship in more than a decade, welcomes 14-time Grand Slam doubles champs Serena and Venus Williams back to the fold against the Netherlands. It’s unlikely they’ll play doubles against the Dutch team: Rather, it’s expected that 2017 Fed Cup hero CoCo Vandeweghe and Lauren Davis will team up.
