Emma Raducanu’s struggles continue with loss to Katerina Siniakova in Miami

• British 11th seed loses 3-6, 6-4, 7-5 to 25-year-old Czech
• Raducanu served for match and within two points of win

Emma Raducanu's tough education in her maiden WTA Tour season continued on Thursday as she served for the match in her Miami Open debut and stood within two points of victory against Katerina Siniakova but failed to take any of her ample opportunities, eventually suffering a bitter 3-6, 6-4, 7-5 loss in the second round.

As Raducanu stumbled, Heather Watson pieced together one of her biggest wins in many years, grinding through a gruelling third set and demonstrating ample resilience by defeating Elina Svitolina, the 15th seed, 4-6, 6-3, 7-6 (4) to reach the third round.
