MIAMI GARDENS, Fla., March 24 (UPI) -- Coco Gauff lost momentum, but summoned sensational court coverage skills to rally past Belinda Bencic on Tuesday in a Miami Open quarterfinal.

The top-ranked American (No. 4) trailed her No. 12 Swiss counterpart 3-2 in the final set, but went on to sweep the last four games, including two break-point conversions, for the gritty victory in Miami Gardens, Fla.

"It was a tough match physically, I think for both of us," Gauff said on the Tennis Channel broadcast after the 6-3, 1-6, 6-3 triumph. "I don't know how I got through it."

Gauff will continue her deepest run at the tournament with a semifinal meeting with No. 14 Karolina Muchova of Czechia.
