Beith eased through against Strathspey Thistle 6-0 at Bellsdale Park after leading 4-0 at half-time.
Darren Christie sent them on their way with an early goal and, before Strathspey had time to recover, David McGowan added a second with a long-range strike.
A double from Kenny McLean – his second from the penalty spot – effectively killed off the tie before half-time.
Beith had the chance to use their bench in the second half and it took them time to add to their tally, Ross McPherson netting the fifth late on.
Nicky Docherty grabbed the sixth to complete the scoring on a miserable afternoon for Strathspey.
A double from Tommy Coyne helped Linlithgow Rose to a 3-0 win at Selkirk, who finished with ten men.
Linlithgow went in front three minutes into the second half when Coyne slammed home a penalty kick.
Coyne added his second seven minutes later and substitute Kevin Kelbie added a third with 14 minutes left.
BSC Glasgow are also in tomorrow’s draw after a 3-1 home win over Rothes with Shaun Bowers, Aidan Ferris and Tom Woods all scoring. Bowers and Ferris scored within a minute of each other early on but Ryan Stuart pulled a goal back to pull Rothes back into the tie.
Both teams had chances in the second half but BSC Glasgow ensured their place in the next round when Woods scored in injury-time.
East Kilbride were top scorers in the round as they thumped Vale of Leithen 9-1 after falling 1-0 behind to an early goal. Joao Victoria scored a hat-trick and 41-year-old player-coach Robbie Winters, pictured below, who has some history in the competition, scored twice – a penalty and a header.
Winters famously played for Aberdeen in the 2000 final against Rangers when an injury to Jim Leighton meant the striker played most of the game in goal, Rangers winning 4-0. There were also two second-half goals from Adam Strachan, sandwiched between a Declan Hughes’ strike.
Gretna 2008 eased into the second round with a 3-0 win at Deveronvale and Preston Athletic won a five-goal thriller at Nairn County, coming through 3-2. Preston led 3-0 at half-time but Nairn hit back through a double from Ross Naismith.
Wick Academy won 3-1 at Dalbeattie Star, who finished the tie with nine men after red cards for Lewis Sloan and Conor Graham.

Civil Service Strollers and Hawick Royal Albert drew 1-1 and Stirling University triumphed 2-1 at Clachnacuddin.
John Hall’s early strike was enough to give Whitehill Welfare a 1-0 win at Edinburgh University, Stuart Knight headed a late equaliser for Forres Mechanics in their 2-2 draw with Lossiemouth and Gala Fairydean Rovers beat Fraserburgh 2-1.
