THERE'S no second prize on offer for this week's semi-finals, but if you can pick the best combination of seven players from either game, a $10,000 prize could well be heading your way with NAB AFL Fantasy Match Day. 

Starting on Friday night, the Crows head back to the MCG seeking revenge for their 2012 preliminary final loss to Hawthorn.

Ball-magnets like Luke Hodge, Patrick Dangerfield and Jordan Lewis pick themselves for Fantasy Match Day.

Hodge finished fourth in the home and away season for average Fantasy points (111.1) and Lewis sixth (110.7).

The Hawks don't have a dominant ruckman like Adelaide's Sam Jacobs, so it makes sense to slot big Sauce into that spot.

Up forward, consider Crow Tom Lynch for a slot in your side. The Hawks are likely to keep the focus on Taylor Walker and Eddie Betts after they torched the Bulldogs last week, and Lynch is set to benefit.

The tall redhead has averaged just under 90 this year and topped the century mark in three of his final six home and away games.

On Saturday night the Roos head to ANZ Stadium to face the depleted Swans with a preliminary final berth at stake.

The Swans have had plenty of Fantasy gold in their midfield this season, and players like Dan Hannebery, Josh Kennedy and Tom Mitchell must be considered.

Fantasy's second-best average in the home and away season belonged to Todd Goldstein, so he goes straight into the ruck slot.

If Brent Harvey can repeat his 101-point effort from last Sunday against the Tigers, the veteran has to come into consideration for your forward line.

You could even punt on Jarrad Waite playing another corker – the former Blue's seven tackles against Richmond, along with four goals, boosted his Fantasy score to a game-high 123.

Make sure you pick your team of seven before the first siren in each game, and you could be heading into preliminary final week with $10,000 sitting snuggly in your bank account.
