Clyde 2-5 Dundee
Fabrizio Ravanelli and Nacho Novo were both on the scoresheet
Substitute Fabrizio Ravanelli opened his Dundee account in stunning fashion with a hat-trick that knocked Clyde out of the CIS Insurance Cup.
The First Division side's hopes of causing a surprise rose after only two minutes, when Pat Keogh opened the scoring at Broadwood.
But Nacho Novo equalised moments later and, although Clyde gave as good as they got until half-time, once Lee Wilkie gave Dundee the lead, the Scottish Premier League side's greater class and fitness began to tell.
Ravanelli grabbed a double before Clyde hit back through Mark Gilhaney, but the veteran former Italian international completed the scoring.
Dundee had gone into the game with serious injury problems and manager Jim Duffy made three changes to the side that drew with rivals Dundee United at Tannadice on Sunday.
Callum McDonald and Craig Burley made their first starts for the club at the expense of injured duo Jonay Hernandez and Gavin Rae, while Juan Sara replaced Ravanelli in attack.
Bully Wee player-manager Alan Kernaghan had to do without on-loan Dunfermline Athletic wing-back Chris McGroarty and dropped John Potter to the bench.
Simon Mensing came into defence, with Stephen McConalogue up front as changes were made to the side that defeated Raith Rovers.
Clyde took the lead after just two minutes of an explosive start to the game.
Jack Ross crossed from the right and unmarked striker Pat Keogh looped a header from 12 yards over goalkeeper Julian Speroni.
But the visitors equalised within two minutes, Nacho Novo stabbing the ball home after Fabian Caballero dispossessed Kernaghan and fed striker Juan Sara, whose shot was headed off the line by Mark McLaughlin.
Clyde goalkeeper Bryn Halliwell did well to deny Novo and Caballero, while Jimmy Gibson forced Speroni into a good save as the match spun from end to end.
But Dundee dominated possession after the break and, with the home side visibly tiring, Dundee went into the lead in the 66th minute.
Fabrizio Ravanelli scored three times within 10 minutes
Scotland defender Lee Wilkie picked up in the centre-circle, strode forward, played a one-two with Caballero and calmly shot past Halliwell from 10 yards.
Ravanelli took centre-stage after replacing Caballero, picking up a pass from Novo after 73 minutes and rattling a left-foot shot past Halliwell for his first-ever goal for Dundee.
The 34-year-old pounced a minute later to score from close range after Halliwell spilled a shot from Sara.
Tenacious Clyde pulled one back in the 78th minute, when substitute Gilhaney shot home from close range.
But Dundee raced up the park a minute later and Sara cleverly fed Ravanelli, who slotted past Halliwell for his hat-trick before being denied a fourth when his shot cannoned off the post.
