Janko Tipsarevic suffers first round exit at St Petersburg

Janko Tipsarevic suffered an earlier exit at the St Petersburg Open than his third seeding promised, as he fell to Roberto Bautista Agut of Spain 7-6 (3 ), 6-3 in the first round on Wednesday.

Tipsarevic, who won the decisive third point in Serbia's Davis Cup semifinal win over Canada on Sunday, squandered seven break points in the second set against Bautista Agut, who broke the Serb twice and closed the match with a backhand down the line on his first match point.

Earlier, sixth-seeded Ernests Gulbis of Latvia and seventh-seeded Lukas Rosol of the Czech Republic both advanced to the second round in straight sets.
