Aidan O'Brien has begun the season in fine form and his Hanky Panky will be a popular choice in the Irish Stallion Farms E.B.F. Fillies Maiden, which kicks off Limerick's card at 4.35.

The half-sister to Giant's Causeway showed plenty of ability in all three starts as a juvenile and she has her sights lowered for her seasonal reappearance.

Daymooma and Bronte showed enough in their opening campaigns to suggest they won't go down without a fight, though.

The most valuable race of the evening is the Summer Twilight Nights Race, in which runaway Irish Cesarewitch winner Voleuse De Coeurs makes her comeback.

The Dermot Weld-trained four-year-old could hardly have been more impressive at the Curragh in October, when following up her impressive Galway Festival success, and another big season is on the cards.

However, this return to 1m4f is not certain to help and that could allow El Salvador, who landed a double over the trip at Dundalk in February, and recent Cork scorer Rich Coast to ask her a few serious questions.

After finishing second and third respectively at Cork recently, Amazing Star and Jackemill do battle again in the www.limerickraces.ie Online Special Packages Handicap.

A length and a half separated the pair that day but John Walsh's representative is 4lb better off this time around and can close the deficit.

They aren't the only ones in with a big shout in this wide-open event, with Treasure The Ridge and Fairylike obvious contenders for powerful yards, and Danzerini entitled to go well on the back of an encouraging Dundalk third.

Silver Lightening made a debut full of promise when narrowly held at the Curragh and the Verglas gelding has a good opportunity to go one better in the UL Racing Society (C & G) Median Auction Maiden, while the O'Brien-trained Marchese Marconi can make it third-time lucky in the Festival Of Speed Maiden.
