Berdych blasts Gulbis to reach Rotterdam tennis semis
Tomas Berdych of the Czech Republic at a Davis Cup match in Ostrava, Czech Republic, on February 2, 2014 - by Michal Cizek
The Czech third seed will await an opponent for Sunday's final from Croatian Marin Cilic and Igor Sijsling of the Netherlands.
Berdych, who has not lost a set all week, dropped just six points on serve in the 29-minute first set as he quickly took charge against Latvia's Gulbis, who earned his place in the semis after putting out top-seeded holder Juan Martin del Potro.
Berdych is bidding for his first ATP title since October, 2012 and was the only member of the ranking top 10 not to lift a trophy during 2013 despite reaching the quarter-finals or better in 15 of his 23 tournaments.
The Czech, ranked seventh in the world, was satisfied after administering the thrashing to the 24th-ranked Gulbis.
He now leads the series 4-2 after playing Gulbis in each of the past six years.
"It was a tough one," said the winner. "I know his game well and I know how good he can play. I knew I had to bring my best game today.
"I played consistent and solid, that is what it takes. it's a formula that has worked so far for me in my career.
"But no matter whom I play in the final, I will have to lift my level. I'm trying to improve my concentration and not ever get distracted on court. I'm playing well, this was a good win for me."
Berdych took the initiative with a break for 3-1 in the opening set, enough of a margin to win it for a solid early lead.
Gulbis was unable to make inroads in the second set as Berdych tightened his grip, earning a break for 5-2 after saving the only break point he faced in the match in the fourth game.
The Czech then claimed victory from two consecutive unforced errors from Gulbis.
