CHICAGO - It wasn't a week ago that trainer Chris Block was mildly bemoaning the way things hadn't quite fallen into place for him at this Hawthorne meet, a stark contrast to last fall, when Block caught breaks, had nothing but live horses, and won a bunch of races. Then came Wednesday. Block won early on the card with a first-time starter in a maiden claimer, but that was only a warm-up. Mystery Giver, the old warrior, called forth his best form from three and four seasons ago, winning a stakes-class turf allowance race by 3 1/2 lengths.
