Fifth seed Dominic Thiem booked his spot in the semi-finals of the Rio Open after cruising past second seed David Ferrer 6-3, 6-2.
Thiem, who is looking to win his second consecutive title after triumphing at the Argentina Open last week, found himself on the back foot early on in the first set as Ferrer broke him to take a 3-1 lead.
However, Thiem fought back and brought himself level at 3-3 by breaking Ferrer in the sixth game. He then went on to take and lead and never looked back as he broke the Spaniard once again prior to clinching the first set.
Thiem maintained his momentum heading into the second set and broke Ferrer twice before converting match point on his first attempt to advance to the last four.
The 22-year-old will face Guido Pella in the semi-finals after the latter came from behind to beat Daniel Gimeno-Traver 5-7, 6-1, 7-5.
Meanwhile, Pablo Cuevas will face top seed Rafael Nadal in the other semi-final after he defeated Federico Delbonis 6-4, 7-6 (4). Nadal progressed to the semi-final via walkover as his opponent, Alexandr Dolgopolov, withdrew due to a shoulder injury.
