Muchova upsets Barty and will face Brady in Australian semis

MELBOURNE, Australia (AP) — Top-ranked Ash Barty has been upset by No. 25-seeded Karolina Muchova in the quarterfinals at the Australian Open. Muchova earned her first semifinal berth in a Grand Slam with the comeback 1-6, 6-3, 6-2 victory. Muchova’s next opponent will be Jennifer Brady. The 22-seeded Brady reached her second consecutive Grand Slam semifinal by beating fellow American and good friend Jessica Pegula 4-6, 6-2, 6-1. Brady struggled at times and gave her racket an angry toss midway through the second set. The unseeded Pegula had advanced beyond the third round at a major for the first time.
