Scott Brown's only goal of the game at home to Cowdenbeath is enough to move Peterhead to the top of League Two - two points above Edinburgh City - as they made full use of their game in hand.

Billy Mckay's hat-trick gives Ross County an impressive win over an Ayr side who started their nearest challengers in League One.

County's win could be significant, especially for Ayr's challenge, as the Dingwall side have a game in hand.
On-loan Aberdeen striker Bruce Anderson's double helped Dunfermline to a 3-0 win over bottom side Partick Thistle that lifts the Pars to within two points of Caley Thistle in the promotion play-off place.

Quote MessageIan McCall can be proud of his players. Some cracking goals. Billy Mckay had a brilliant hat-trick. Sometimes players of his class just know where to be, how to move. But a special mention to Ross Doohan, who pulled off some fantastic saves

Quote MessageIan McCall shuffled the pack and Ayr United came to life. Billy Mckay was exceptional. I have to compliment both sides as they left everything on the pitch, but Ross County for me shaded it. Brilliant entertainment
