4 To Win is Betway's free-to-play prediction game, with a £1,000 prize on offer every single day and an increased jackpot of £10,000 for all ITV meetings.

Simply guess the winner of four chosen races for your chance to claim the cash. Here are Alan Alger's top tips for Saturday at the Doncaster St Leger...

13:50 DONCASTER

TOP PICK: GOLDEN APOLLO

Second choice: Marnie James

We have a tough sprint handicap to open up with.

It looked as though the far side of the track was favoured in midweek with low to middle numbers dominating the Weatherby’s Bank two-year-old race.

Sometimes, though, it’s the positioning of the pace in the race that counts.

Course winner GOLDEN APOLLO was a beaten favourite last time out when he was probably hindered by the draw at Ripon.

But he's progressive and can win at this level, as evidenced at Ascot last summer.

14:25 DONCASTER

TOP PICK: OH THIS IS US

Second choice: Mustashry

This is an open Group 2 despite the small field.

The last five renewals of this race have produced winners under 5/1, although only one of those was a clear favourite.

OH THIS IS US won well at Chester last time and can follow up over a course and distance where he has already been a winner.

15:00 DONCASTER

TOP PICK: TOO DARN HOT

Second choice: Bye Bye Hong Kong

TOO DARN HOT can justify favouritism for next year’s Derby by taking this Group 2 contest.

This is an unusually simple odds-on selection in a 4 To Win Saturday race.

15:35 DONCASTER

TOP PICK: KEW GARDENS

Second choice: Dee Ex Bee

The fifth and final Classic of the flat racing season and, historically, the oldest one of all.

Lah Ti Dar is three from three after missing her juvenile season and appearing for a debut at Newbury back in April.

She’s very impressive but hasn’t tackled any Group company yet. She is therefore opposable.

I’m going for proven stayer KEW GARDENS, whose win in the Queen’s Vase has set him up nicely for this.
