YORKSHIRE champion Jamie Bower and Selborne Salver winner James Walker were seven shots off the first-round lead in the Lytham Trophy at Royal Lytham & St Annes GC.
Both shot 74 as Sundridge Park's Alfie Plant - the man who beat Bower in a semi-final sudden-death play-off in last year's English men's amateur championship - carded a three-under-par 67 to hit the front.
Hull GC's Steve Robins and Rotherham GC's Jonathan Thomson produced rounds of 76, Lindrick Scratch Open champion Ben Brewster (Wheatley GC) and Bedale GC's Dan Brown are on 79 and England A squad member Will Whiteoak (Shipley GC) 80.
Bower, who won two titles earlier this year while touring South Africa with England Golf's men's squad, suffered a double bogey at five and remained two over through 13 holes, following a bogey at 12 with an immediate birdie. Two shots shed at 16 and 17 led to his 74.
The Oaks GC's Walker sandwiched birdies at seven and 11 with bogeys at four, five, 12, 15 and 16.
Thomson and Robins each had two birdies in their respective rounds, but the latter also incurred two double bogeys.
Brewster looked set for a score similar to that of Bower and Walker only to suffer a quadruple-bogey eight at the 464-yard 15th.
Dutch Junior Open champion Brown was unable to find any birdies, nor Whiteoak, whose equilibrium may have been jolted by being five over after as many holes.
Rotherham GC's Charlie Daughtrey was in second place just two shots off the lead after the first round of the Fairhaven Trophies event at Fairhaven GC.
Daughtrey carded a level-par 72 and was two shots adrift of Cumberwell Park GC's James Cooper.
Other Yorkshire competitors are Fulford GC's Charlie Thornton (75); Wakefield GC's Daniel Bradbury (76); Hallamshire GC's Barclay Brown (79); Hallowes GC's Sam Bairstow and Rotherham's Aaron Nairn (both 80); Howley Hall GC's Tim Seidel (81); Hessle GC's Abigail Smee (83); Hallamshire's Alex Fitzpatrick (84) and Howley Hall's Tom North (85).
