Joanna Morgan saddled the first two home as Fourpenny Lane wore down San Sicharia in the final furlong of the Listed Cooley Fillies Stakes to give Johnny Murtagh a double at Dundalk.
San Sicharia had hit the lead under two furlongs out but had no answer when tackled by her stable-mate inside the final furlong.
Fourpenny Lane went on to score by half-a-length to justitfy 6/4 favourtism.
"It was a great performance by the both of them. They are two very sweet fillies," said Morgan.
"The other one (San Sicharia) might have needed it as she went home for a while.
"I've always rated her slightly better but the 5lb would have matched them up. I'm delighted with them.
"Paddy Twomey (owner) has been a great supporter of the yard and deserved that. Both are going to the sales so it's job done."
There was a sting in the tail for Murtagh who received a one-day ban for careless riding, concerning an incident early in the straight.
It rules him out of the last day of the season here on November 27th.
