Ravin Maniac shook free in the stretch of the sixth race on Sunday at Arlington Park to post a 1 1/4-length win under Tim Thornton and become the first career winner for classic-placed freshman sire Scrimshaw.

After a third-place finish in her career debut on April 30 at Hollywood Park, Ravin Maniac pressed the pace in the 4 1/2-furlong maiden special weight race and seized command on the turn en route to a victory in :52.27 for trainer Larry Rivelli, who co-owns the dark bay or brown filly with Richard Ravin. Ravin Maniac is out of the winning Boston Harbor mare Radcliffe Yard.

Scrimshaw, an eight-year-old by Gulch out of the winning Sham mare Rogue Girl, stands for $3,500 at Millennium Farms in Lexington. A half brother to stakes winner Vogue Girl, Scrimshaw has 76 two-year-olds in his first crop.

Scrimshaw won four of 13 career starts and earned $461,842 in three seasons. He won the Coolmore Lexington Stakes (G2) at Keeneland Race Course in 2003 and finished third that year in the Preakness Stakes (G1).
