Senado Square repeated his success of 12 months ago in the 47-65 event over six furlongs at Dundalk this evening.
Cian Horgan produced his mount with a well-timed charge to lead passing the furlong pole.
The Andy Slattery-trained gelding held the late charge of I'm Spartacus by a neck to score at odds of 8/1.
It was a fourth career victory for Senado Square, with three coming at this venue.
Assistant trainer Brian Slattery said: "He's a bit frustrating, he's a better horse than what he ever shows.
"When he won in Naas first time out as a three-year-old, we thought he was a good horse. To be honest, he has disappointed us since.
"We thought he was right there about a month ago and that he would win a few races. He hasn't, but he did a good bit of work last week.
"That might be Cian's last ride because he is heading to England. He might have to put it off now until Wednesday because he is in again then.
"Cian gets on very well with him, he is not straightforward in the stalls. To be fair, Cian has done a lot of work with him in the stalls and he has done a great job on him. He has won his three races on him up here."
Horgan told Racing TV that he is set to join David O'Meara's yard in Yorkshire.
