Bernard Tomic took a while to warm up before steaming into the final of the Acapulco Open in Mexico with a three-set win over Alexandr Dolgopolov.

The fifth-seeded Australian was sluggish in the opening set but got into a groove to score a 1-6 6-4 6-3 semi-final victory on Friday.

It was Tomic’s second successive triumph over a Ukrainian following a straight-sets win over Illya Marchenko.

The world No.21 will play his fifth career ATP final against the winner of the other semi between Dominic Thiem and Sam Querrey.

Tomic has not played Thiem before and hasn’t lost to Querrey in three encounters.

The 23-year-old Queenslander will be chasing his fourth ATP title to add to crowns won in Sydney (2013) and Bogota (2014 and 2015).
