The 47th-ranked Latvian capitalized on the eighth-seeded Swede's double-faults in the first and the fifth games of the first set, and won four consecutive games in the second. He finished with 11 aces.
"I caught my rhythm from the very beginning," Gulbis said. "I know him well, we practice together. He hasn't played even to 50 percent of his potential today."
The 19-year-old reached the semifinals in his ATP debut in St. Petersburg last season. Johansson won the 2002 Australian Open and here in 2005.
The 27th-ranked Russian traded breaks with Melzer in the first set before heading to the tiebreaker. In the second set, Melzer saved four break points in the 11th game.
"The first match is always difficult," Tursunov said. "It's not easy to play against a left-hander especially on a fast carpet here."
