Sunday tips: Angus McNae's best bets including the Irish Derby

Alpha shaped with a good deal of promise on her debut at Leopardstown, running on takingly under a considerate ride to finish second. 

It was surely significant that she was well backed that day and she has a fine pedigree being by Sea the Stars out of the Group One-winning mare Alpha Centauri. 

She looks certain to take a big step forward with Ryan Moore taking over in the irons. 

Issac Newton got his act together when winning a Listed race at Navan last time out and can take another step forward today. 

He overcame plenty of trouble in running that day utilising a sharp turn of foot and having just had seven career starts he is open to plenty of improvement. 

He was Group One-placed as a two-year-old and I expect him to be good enough to land this strong Group Three contest. 

It should not be underestimated just how heavy the conditions were at Epsom for the Derby and although Benvenuto Cellini was declared a non runner he clearly did not give his running under those conditions. 

He is much better judged by his Chester Vase success where he won by 4 ½ lengths in a fast time. 

He has a long stride and a low cadence which means he should be ideally suited to a mile and a half, but most importantly he moves like a horse who needs fast ground to give of his best and conditions today will suit ideally. 

Rolltight makes his handicap debut off a mark of 88 and that could be a generous rating given that the form of his maiden win at Gowran Park last time out got a boost on Friday when the runner-up Loughrea won at the Curragh. 

He steps up a furlong in trip which looks sure to suit and although this is a competitive handicap he is one of the least exposed runners with plenty more to give.
