STILLETO BOY (g, 5, Shackleford–Rosie’s Ransom, by Marquetry), on the board in five prior Grade I events for these connections, scored a breakthrough success in Saturday’s GI Santa Anita H. as he ran down pacesetting favorite Defunded (Dialed In) and held off GISW Proxy (Tapit) to post a 13-1 upset in 2:01.96. Acquired for $420,000 at the Fasig-Tipton July HRA sale in 2021 off a win in the Iowa Derby, the chestnut has racked up nearly $1.5 million since then. Third in last year’s running of this race, he annexed the GII Californian S. next out, and was most recently third–one slot behind Defunded–in the GI Pegasus World Cup Invitational S. Jan. 28. Sales history: $420,000 HRA FTKJUL ’21. O-Steve Moger. B-John & Iveta Kerber (KY). T-Ed Moger, Jr.
