Looks like they recently changed the rules on them.
I've had winners voided in the past because the game was not complete (SF/Colorado, I had both pitchers under in Ks), but yesterday I bet Kershaw under and it was graded a loss, and now when I check the props they don't mention 9 innings being necessary.
* Game Note: Spread and Total Strikeouts by the 2 starting pitchers. Pitchers must start for action.
