The 20-cent Rainbow 6 wager is up next here at Gulfstream with Race 7, with the track guaranteeing a pool of $1.25M for a solo-sweep windfall. At least in terms of the large fields, it looks like a pretty tough sequence, although it'd take a few blow-up prices for somebody to take the whole thing down.

With 6 of the 12 races in the books, it's been a pretty chalky day here so far, with the notable exception of race 2, when a pair of 25-1 shots combined for an exacta (6-8) that returned more than $1,300 for a deuce.

Also worth noting that a $250k guarantee is in effect for the late pick-5 (R8-12) and $300k for the late pick-4 (R9-12).
