A filly from the first crop of Stonewall Ocala stallion Da Stoops showed off her talent during the first session of the Apr. 13 under tack show for the OBS spring sale of 2-year-olds in training. She worked the fastest quarter mile of the day, getting the distance in :20 2/5 seconds. Watch the workout video.

The bay filly is out of the unraced Montbrook mare Magical Promise and is a half-sister to the winner Magical Tiger. Other stakes winners on the filly's distaff side include Belmont (G1) hero Da' Tara and Grade 3 winner Denis of Cork.

The filly's consignor is Blue River Bloodstock, agent. Cataloged as Hip No. 88, she will sell on day one of the four-day sale, which runs Apr. 19-22.

Da Stoops has had three juvenile sell at auction thus far in 2010, for an average of $63,000, which is 18 times his stud fee.
