Arella Rockstar pulled away in the late stage of a six-furlong maiden race Wednesday at Saratoga to win her debut by 2 3/4-lengths to give Taylor Made freshman sire Astrology his seventh winner. Astrology ranks in the top 10 on the First-Crop Sire list by both winners and progeny earnings.

Arella Rockstar battled through the first half-mile with the 7-5 favorite Jax, then put away the favorite at the top of the stretch for the win.

The winner was bred in Kentucky by Machmer Hall and is the first foal out of Story Untold, who is a half-sister to multiple graded stakes winner Feline Story.
