Three current Top 10 players and former World No.1 Caroline Wozniacki will headline next month's regional events for the Billie Jean King Cup by Gainbridge.

World No.8 Zheng Qinwen, No.9 Maria Sakkari, No.10 Jelena Ostapenko and Wozniacki are scheduled to anchor their countries' lineups in Group I action at the prestigious women's tennis team tournament. Group I play will take place at three locations from April 8 to 13.

These Group I events will determine who advances to November's Billie Jean King Cup Play-offs, with potential spots in the 2025 Billie Jean King Cup Qualifiers and Finals on the line.

The Europe/Africa Group I event will take place in Lisbon, Portugal, where Sakkari's Greek squad, Ostapenko's Latvian team and Wozniacki's Danish lineup will be among the 12 contenders. Wozniacki is slated to make her first Billie Jean King Cup appearance since 2015.

The top four teams from Europe/Africa Group I will reach November's Billie Jean King Cup Play-offs.
