Which jockeys and trainers at Parx Racing have been hot? Funny you should ask: we wondered the same thing.

So we created a quick-and-dirty metric for the handicappers among us. The metric includes wins, win percentage, and wagering return on investment in one number. To limit it to who’s hot, we’ve included data from just the past 50 or so days — since January 1, 2021.


Ruben Silvera, the wins leader with 19, also tops our list with a score of 102. That’s just ahead of Angel Castillo (101), with Silvestre Gonzalez and Edwin Rivera not far behind.

Castillo has the highest wagering ROI thus far +23%), while Rivera also is on the plus side of that ledger. Gonzalez, winning at a 20% clip, is tops among the leading riders in that category.

The average score of all riders at Parx was 50.8.


While Jamie Ness is once again leading Parx Racing by wins with 15, he stands just sixth on the list of hottest trainers with a still-solid score of 102. The bettors — not surprisingly, given his high win percentage in recent years — are on to him, and his wagering ROI is -41%.

Three trainers — Daniel Velazquez, Howard Brown, and James Noble — top the 120 mark, with Velazquez (129) narrowly in front. His 7-for-20 record gives him a 35% strike rate (best among trainers with more than two starts). And for good measure, he has a +42% wagering ROI.

That latter number is great — but it pales next to Brown’s +227%. Brown’s four winners this year have gone off at 5-2, 18-1, 9-1, and 7-1, which is a pretty nice wave to ride.

The average score for Parx trainers was 45.5.
