Russell Baze reads the Form. Russell looks at videos of past races. He sizes up his horse and the competition in each race and puts his horse where it has the best chance to win. He is sharp jockey and would make a great trainer. I don't have any numbers, but it seems to me his horses survive an high percentage of speed duels. He is good guy and good for horse racing. He would win on anybody's horses.
Jockey ROI is not a sufficient or necessary measure of jockey talent. Some jockey/trainer ROIs are interesting, but that's about it. Check out these numbers compiled in October 2011 for the previous 36 months at Santa Anita:
Jockey %ROI Win/%ROI Place/%ROI Place
SprintsBejarano 89/87/88
Garrett 94/85/89
Talamo 57/74/88
Agapito 101/95/74
Court 24/46/72
RoutesBejarano 79/80/86
Garrett 96/88/87
Jon Court 13/38/46
Kayla Stra 273/87/84
All have losing ROIs except Kayla (56 starts/4wins) and Agapito. Agapito would only have to lose another race or two to go into the red. Kayla the kind of jockey you'll have to play to make this angle work -- hope she brings home a big longshot once a year or so. Court must not get the horses. Garrett is a bit worse than a slot machine: it will take longer than most jockeys to lose your money betting him every race.
