Indiana Sire Stakes action got underway during a spectacular 15-race Memorial Day card on Monday (May 25) at Harrah's Hoosier Park. The headline was the sophomore debut of world champion Odds On Mr Mamba, who returned with a 1:49 first-over score in the $96,000 3-year-old colt and gelding pace with Dexter Dunn aboard. Leaving from post two in the full field of 10, Dunn floated the 1-9 favorite into fourth on the first turn while Dancingdreamer (Aaron Stutzman) blitzed to the lead around What Nooo Waaay (John De Long) to reach the opening station in 26 2/5. Dancingdreamer kept the throttle down to the half in 54 2/5 before Dunn began to angle Odds On Mr Mamba off the cones. The field scorched into the final turn, with Dancingdreamer continuing to lead the way to the three-quarter pole in 1:22 2/5 while Odds On Mr Mamba powered alongside What Nooo Waaay before setting his sights on the leader. Dunn began to call on Odds On Mr Mamba at the head of the lane, with the world champion responding and powering clear of Dancingdreamer. Strong through the wire, Odds On Mr Mamba paced his final panel in 26 1/5 en route to a 2 1/4 length score in his 1:49 clocking. What Nooo Waaay edged out a hard-charging Swiss Lights (Trace Tetrick) for the place position.  The victorious Odds On Racing homebred gelded son of Odds On Equuleus-Honky Tonk Woman has now won eight straight dating back to last season, with his lone defeat coming in his career debut. Trained by Melanie Wrenn, Odds On Mr Mamba now boasts a career bankroll of $362,405. Far from the only star on the Monday card, the Hoosier State's best put on a show, with all other sophomore divisions offering a pair of splits for their first leg of Indiana Sire Stakes. The Sire Stakes action kicked off with a bang, as Somemore Blue (Marcus Miller) took the lid-lifter in a career-best 1:50 in the $48,500 first division for sophomore pacing fillies. The 1-9 post time favorite out of post two, Somemore Blue eased through the gate to the rail behind Klorox Queen (Trace Tetrick). Klorox Queen led the field early to the first quarter turn in 27 1/5 contested by Somemore Blue. The six-horse field entered the backstretch single-file led by Klorox Queen, and the field remained unchanged to the halfway point in 56 1/5. The pattern continued to three-quarters as Klorox Queen was followed tightly by Somemore Blue. Transitioning into the stretch, Somemore Blue sprung to life along the outside of Klorox Queen, taking flight in 25 3/5 to better that foe by two lengths, while Keeps Miss Dixie (Brandon Bates) rallied for third at 42-1. Somemore Blue is owned by Douglas Overhiser, Kenneth Duffy, Lava Java Stable, and Never 2 Late Stable and trained by Erv Miller. The Rockin Image-Misssomebeach Blue filly was bred by Lavon Miller.
