Thursday's Monterrey quarterfinal pits Alycia Parks against Ann Li on hard. Ann Li has won 4 of the last 10. Alycia Parks has won 5 of the last 10.

There's a wide gap in our ratings on hard, and our number follows from it. Parks comes in off a compressed schedule. A tiebreak or two would surprise nobody, with Li fractionally more likely to land the big points.
