(Reuters) -Top seed Carlos Alcaraz and Daniil Medvedev booked their spots in the Miami Open semi-finals with wins over American opponents on Thursday, while Elena Rybakina saw off world number three Jessica Pegula to reach the women's final.
Taylor Fritz showed great fight but was unable to match Alcaraz's level, the defending champion taking control with an instant break of serve in each set on the way to a 6-4 6-2 win.
