Watson is yet to drop a set in the singles at the Junior Fed Cup

Guernsey's Heather Watson helped Great Britain to their second straight win in the group stages of the Junior Fed Cup singles event in Mexico on Wednesday.

The 16-year-old followed up her straight-sets win over China's Wen Xin on Tuesday with a 6-0, 6-2 victory over Mexico's Karen Hernandez.

Tara Moore won the other singles rubber before Watson and partner Amy Askew beat China in the doubles.

The pair were a set down but went on to beat Xi Bai and Xin Wen 6-7, 6-3, 6-3.

Great Britain, who are top of their group, face Chile on Thursday to decide who ends up in first place.

Chile beat Mexico 2-1 in the other match in their group.
