ROME — Iga Świątek ’s struggles continue, at one of the last places anyone in tennis would have expected. Świątek, a master of clay-court tennis and defending champion at the Italian Open, lost to American Danielle Collins in the second round, falling 6-1, 7-5.

Iga Swiatek suffered a shock elimination from the Italian Open on Saturday as the reigning Rome champion was dumped out by Danielle Collins 6-1, 7-5.
