Emma Raducanu’s run at the Miami Open came to a difficult end in the quarter-finals on Wednesday night as she was toe-to-toe with Jessica Pegula for two and a half hours before being outlasted by one of the best players in the world. After bruising, classy 3 sets under the lights, the fourth seed  maintained an excellent level in the final stages as she closed out the match 6-4, 6-7 (3), 6-2.
