London, UK, 29 June 2016 | AAP

Rain has stalled Bernard Tomic’s push to join Nick Kyrgios and fellow Australians John Millman, Daria Gavrilova and Sam Stosur in the second round at Wimbledon.

Tomic was all locked up at two sets apiece – 4-6 6-3 6-3 3-6 – with Spaniard Fernando Verdasco when the heavens opened and forced the suspension of play at the All England Club late on Tuesday.

Wimbledon debutant Matt Barton was locked in a first-round dogfight with qualifier Albano Olivetti when rain stopped play.

Barton hasn’t offered up a break point but trails 6-7(7) 6-6 with the pair locked at 5-5 in the second set tiebreak.
