Three of the day's five grass races were won by an early leader, but we also had a mid-pack stalker in a turf sprint, and a deep closer in a turf route. So, no bias. Mid-card rain added more moisture to a course already labeled "good," but Sweet Relish, pressing winner of race 9, just went a mile in aout 1:37.60, so the turf clearly does not have much give in it.
Obviously, with all this grass racing we have little to report Polytrack wise. From the three races on the main track, it appears the Poly has no bias and is producing times in an average range.
Nothing bias wise all week in terms of Polytrack. Neither has the speed of the surface varied all that much, especially when laid next to that week.
