Aberdeen’s run without a victory extended to four games after they were held to a 0-0 draw by Partick Thistle at Firhill.
Both teams cancelled each other out with chances few and far between.
The result leaves the Dons five points adrift of second-place Rangers, while Partick are four points better off than bottom of the league Ross County.
The Dons made two changes from the side that started last week’s 1-1 draw with Kilmarnock in the quarter-finals of the Scottish Cup. Kari Arnason and Adam Rooney dropped out with Andrew Considine, back following suspension, and Dominic Ball both starting.
The incessant rain made conditions difficult for both sets of players but it was the Dons who were first to try their luck with Ball firing wide from 20 yards before Kenny McLean with a curling effort from 15 yards out.
There was a moment of controversy after 24 minutes when Ryan Christie appeared to prevent Jags captain Chris Erskine race through on goal but referee Greg Aitken waved play on.
The Dons should have broken the deadlock after 33 minutes when Christie cut the ball back to the unmarked Graeme Shinnie but the Dons captain’s effort was well saved by Tomas Cerny.
McLean, Aberdeen’s best player in the first half, showed a great turn of pace to create the Dons’ next opening but Stevie May couldn’t convert from close range.
Partick Thistle went close three minutes into the second half when Erskine’s looping header was nodded off the line by May.
The game began to get stretched as both teams pushed forward with McLean unlucky to see his dipping free kick fly just over.
But it was Partick who went closest to a winner with substitute Ryan Edwards drawing a superb save from Woodman.
