Presenting Mahler was the third winner in-a-row to make all at Galway, as she took the feature Guinness Handicap Chase.

The John Ryan trained nine-year-old was successful at Listowel last month, and she was last seen finishing fourth to Drakaina at Limerick on Sunday.

Turned out again quickly she was went off a 9/1 chance, and was sent straight to the front by Danny Mullins.

She was pressed before the last by Show And Go but pulled out more under pressure on the run-in, going on to score by half a length.

The fast finishing Black Zero finished second under Mark Enright for Michael McDonagh at 14/1, while the aforementioned Show And Go (9/1) was a head away in third, with Phillip Enright in the saddle for Henry De Bromhead.

The well-backed 7/2 favourite (from 9/2) Tesseract finished a disappointing sixth under Barry Geraghty for Joseph O'Brien.

Ryan said of the Patrick McKeon owned chestnut: "She is a smasher and will probably go up in the handicap now and will run in those mares chases.

"She is a fair detail, she's improving, loves the winter ground and can of course go back hurdling as she's rated 106.

"We gave her a run (on Sunday) as she is really stuffy and that run at Limerick must have put her spot on for today. You need to work her hard as she is a stuffy mare but only for her making a mistake at Limerick she would have won that as well."
