MADRID, April 27 — Stefanos Tsitsipas suffered a surprise second round exit at the hands of world number 118 Thiago Monteiro in Madrid today, while Iga Swiatek cruised into the last 16 on a rainy day at the Caja Magica.

Tsitsipas, who arrived in the Spanish capital with only one defeat on clay this term, lost 6-4, 6-4 to the Brazilian qualifier in just over 90 minutes.

The Greek world number seven had a first round bye and came into the tournament on the back of a third title triumph in Monte Carlo and a runner-up showing in Barcelona in the previous two weeks.
