England's Charley Hull is playing in the UL International Crown after missing the second session because of asthma and fever.
Hull joined partner Melissa Reid for the start of their match on Saturday against sisters Ariya and Moriya Jutanugarn of Thailand.
The 20-year-old Hull sought medical attention when she arrived at the course Friday. She was hoping to join Reid at some point, but the medical team advised her to rest.
England began Saturday's session on top of Pool B with five points. The top two teams in each pool and the winner of a wild-card playoff between the third-place teams advance to singles matches on Sunday.
