After a promising start of the season, Jaume Munar lost nine straight matches since Barcelona, losing ground in the rankings and heading to Gstaad motivated to change that. The young Spaniard had to work hard in the first match, defeating Malek Jaziri 5-7, 6-3, 6-4 in two hours and seven minutes to end the losing streak and earn valuable points.
Munar served well and faced only two break points, getting broken once and erasing that deficit with two successful return games in sets two and three that propelled him over the finish line. Jaziri moved ahead in the 11th game of the first set, saving a break point for a 7-5 before Jaume responded with a rock-solid set number two, forging the lead in game six and closing the set with a hold at love at 5-3 to set up a decider.
There, he barely lost a point on serve and delivered the crucial break at 2-2 before two holds at love in games eight and ten that pushed him into the last 16. Making an ATP debut, a qualifier Gian Marco Moroni ousted the Spanish veteran with a wild card Tommy Robredo 6-2, 6-2 in an hour and ten minutes, dropping only 14 points in eight service games and stealing Robredo's serve twice in each set to control the scoreboard all the time.
The 5th seed Joao Sousa needed an hour to oust Steve Darcis 6-4, 6-4 in a close match, fending off both break points he played against and stealing the rival's serve twice for a winning start. Sousa grabbed a break at 3-3 in the opener, repelling two break chances in the next game and closing the set with a hold in game ten.
The Portuguese served well in set number two as well, breaking Darcis at 1-1 to carry the advantage home and stay on the title course. Taro Daniel took down a qualifier Filippo Baldi 6-4, 6-4 in an hour and 14 minutes, controlling the pace in his games with just 15 points handed in ten service games and taking the Italian's serve three times for straight sets triumph, his tenth on the Tour in 2019.
Albert Ramos-Vinolas proved to be too strong for Henri Laaksonen, delivering a 6-0, 6-3 victory in 62 minutes and improving to an 18-17 score this year. Albert was in the right rhythm from the very first ball, dropping only 11 points in his games and saving all four break points to mount the pressure on the other side.
The Swiss gave away almost half of the return points, allowing Ramos-Vinolas to break him four times and march towards the finish line.
