Ann Li beats Alycia Parks 6-2 6-3 in Monterrey quarterfinals

Ann Li produced a clean, controlled performance to beat fellow American Alycia Parks 6-2, 6-3 in the Monterrey quarterfinals, never allowing the match to tighten. The difference was serving stability: Li landed 61.5 percent of her first serves and won 87.5 percent of those points, adding four aces against a single double fault. Parks, by contrast, found only 48.7 percent of her first deliveries and coughed up 11 double faults, leaving herself exposed on a second serve that yielded just 30.8 percent of points. With 55 percent won behind her own second ball, Li had margin all afternoon and moved into the semifinals.
