Fascinatin’ Rhythm was no match for either Five Diamonds or Sweet Goodbye when they met two months ago in the six-furlong What a Summer. But after turning in one of the fastest races of her career in last month’s Grade 2 Barbara Fritchie Handicap, followed by a bullet four-furlong workout last week, the 6-year-old Fascinatin’ Rhythm was in peak form for Saturday’s $75,000 Conniver Stakes at Laurel Park.
