Three weeks down, three more to go in the Boylesports Irish Greyhound Derby and, of the first half of the classic, one thing is certain: Ballymac Matt has been dominant.

Outright favourite Ballymac Matt produced another faultless display, when posting the fastest time of the second round of the Boylesports Irish Greyhound Derby on Saturday night at Shelbourne Park.

One hundred and forty-four greyhounds will contest the opening round of the Boylesports Irish Greyhound Derby, following the draw, which took place yesterday morning at Shelbourne Park.
