Guajardo scored in the 49th, 62nd and 75th minutes for the Mexicans, who are undefeated after two matches in the eight-team tournament.

Rosario Saucedo scored in the 21st minute, Marylin Diaz in the 27th, and Jennifer Ruiz in the 38th and 71st.

Mexico wraps up group play against the United States on Tuesday in a game that likely will determine first place in their group.
