The pair celebrated Daniilidou's 31st birthday last Thursday and joined forces to beat Melanie Oudin and Taylor Townsend, 6-4, 7-6 (2), in the Albuquerque final.
“It’s great fun to win any title anywhere and to do it with a friend like Eleni is even better,” Vandeweghe told the Albuquerque Journal.
Daniilidou countered with a laugh.
“We are great friends now,” she said. “To be honest, two years ago we hated each other. Life is strange sometimes.”
Vandweghe, who had lost her first three singles meetings with Daniilidou, beat her doubles partner, 6-0, 6-3, in the Albuquerque singles round of 16.
