Joining the fray were Spaniard Javier Barcos Garbayo, Samuel Slater and Yannick Malik who joined Bovari in second place at 4-under par.
Slater carded the round of the day on Friday, making two eagles and five birdies on his way to a 66 (-6). The Austrialian nearly signed for a 65, narrowly missing a short birdie putt on the 18th hole.
A total of 13 players are within four shots of the lead, including the World Amateur number No. 3, Ludvig Åberg of Sweden, who sits at -1.
