Hume's boost
The former Scottish Amateur champion, who played on the Asian circuit in 2006 and 2007, fired a five-under 66 and surged up into 12th place with a four-under 138. Hume, 27, heads into the closing two rounds eight shots behind Spanish leader Gabriel Canizares, son of former Ryder Cup player Jose Maria, who hit a 66 for 130.
Musselburgh's Lee Harper, the Scottish Boys' champion in 1999, posted a 71 for 139 to share 15th but Comrie rookie Wallace Booth dropped down to 36th after a two-over 73 left him on 142. Aberdeen's Clarke Lutton missed the halfway cut on 155 after a 79.
