J J Grey (Street Boss), who was riding a two-race winning streak heading into Saturday's Iowa Derby at Prairie Meadows, recorded the hattrick when wiring his rivals in the 8 1/2-furlong sophomore contest.Fleet-footed at the start, the grey broke on top and despite losing the advantage for a brief moment, he regained the lead by the time the field it the first turn. Completing a quarter in :23.84, J J Grey continued to show the way through a :47.95 as favored Desert Gate (Omaha Beach) stalked a couple of lengths behind the pace. Starting to get some pressure from Bricklin (Nyquist) as Desert gate found clear running and took off after the front-running pair.Still in front straightening for home, J J Grey spurted clear as The Hell We Did (Authentic) launched his rally along the inside. Despite The Hell We Did's best effort to reel in the front runner, the grey had enough left to hold that rival off by 1 3/4 lengths at the wire. Maximum Effort took the show spot. The 6-5 choice Desert Gate tired to fourth.A debut winner at Colonial last summer, J J Grey failed to hit the board in three subsequent tries during his juvenile campaign. A winner at the Fair Grounds in March, he was sixth on the synthetic in Turfway's Mar. 21 Rushaway Stakes before coming home seventh in a Keeneland turf allowance on Apr. 10. Blasting home a 5-length winner in an Oaklawn optional claimer on May 2, J J Grey added another confident score in the Prairie Mile Stakes on June 13.This is the family of SW and GISP and Mid-Atlantic leading sire Great Notion (Elusive Quality).Click for the Equibase.com chart or VIDEO, sponsored by FanDuel TV.
