Emma Raducanu woes continue as Brit loses Miami Open debut to Katerina Siniakova

Emma Raducanu lost her first match at the Miami Open from a set up to continue her recent run of early losses. The match looked to be virtually over early in the first set when her opponent Katerina Siniakova struggled physically and needed physio treatment multiple times but managed to come back from a break down twice in the final set to close out a 3-6 6-4 7-5 win in two hours and 56 minutes.

Raducanu was making her Miami Open debut, still experiencing her first full year on the pro tour after shooting up the rankings when she won the US Open as the 150th-ranked qualifier in September. The world No 13 is the 11th seed this week and received a bye to the second round, where she faced Katerina Siniakova.

The 19-year-old walked onto court with her left knee taped, having picked up an injury in Mexico last month. She was pushed to deuce in her opening service game but managed to hold on and threatened the doubles No 1's serve as she forced seven break points but was unable to capitalise on any as Siniakova held, with the pair needing 16 minutes to get to 1-1.

But Raducanu then won eight points in a row to find herself 3-1 up with a break as the 25-year-old shouted in frustration and requested the physio for the next changeover. Siniakova was in tears as the physio arrived to the court with the Czech 1-4 down, as she received a medical time-out for what appeared to be a rib injury - the same issue Rafael Nadal picked up in Indian Wells that has forced him out for four to six weeks.
