Defending champion Carlos Alcaraz reached the last 16 of the Madrid Open as he cruised past Thiago Seyboth Wild.
World number three Alcaraz won 6-3 6-3 against Brazil's Seyboth Wild.
The win continues second seed Alcaraz's dominance at the event, which he won in 2022 and 2023.
"Today was the test of fire, no discomfort, feeling spectacular, from here, we'll be getting better," said Alcaraz, 20.
The Spaniard was again sporting a compression sleeve on his right arm following an injury which caused him to pull out of the Barcelona Open this month, but he showed no signs of discomfort in a straightforward win over his unseeded opponent.
