Bob,
Rich's settings may differ slightly, but the auto-paceline selector (Best of last 3 comparable distance/surface) chose the sprint. If you chose the 'extracted sprint' from either of its last 2 routes the horse ranks even higher on BL or Rx rankings.
The horse ticked all the other boxes on impactful rankings: consistency of Speed (CSR) and other external rankings non-correlated to speed/pace/deceleration - namely Morning Line, ProfitLine, Prime Power. If you use either of its last 2 routes, it also rates rank 1 or 2 in all 'Sartin' ratings. From a 'story-line' analysis, it had been off for 2 years (likely injury in Jan 2016), now returning slowly and trying to find a competitive level, also proper distance for whatever it has still got to give. Hard to eliminate it, and the Exacta with the #8 was just a gift from the racing gods!
