(Reuters) - Serena Williams retired from the BNP Paribas Open while trailing Spain’s Garbine Muguruza 6-3 1-0 at Indian Wells on Sunday.
Williams walked to the chair after the first game of the second set and sat down, breathing heavily. She and supervisor Donna Kelso had a discussion and Williams retired.
