Tomas Berdych and Milos Raonic headlined the competitors at the 2014 Portugal Open. They have done their part by advancing to the quarterfinals.
Raonic is looking for his first career title on clay and first title of 2014.
Berdych aims to end his clay-court title drought. He has not won a title on the surface since Munich in 2009.
The other seeds have not fared well, with five out of six going down early. The only other seed remaining in the draw is the Spaniard Marcel Granollers.
None of the men remaining has ever won the Portugal Open. The last remaining past champion, Albert Montanes, was knocked out by Granollers in the last round.
Let's take a look at who will be taking a step closer to winning as well as break down the quarterfinal matchups.
