Project for anyone with a database I will do the UK trainers later, but for now here is how the top Irish trainers have done at start of flat season with horses returning from a lay off. Data is for all races in March, April & May over last 5 seasons for horses that were returning after an absence of between 5 to 10 months.
1. Willie McCreery - 73 bets, 12 wins, 17 places, LSP = +20.30, A/E = 1.44
2. Mrs John Harrington - 110 bets, 17 wins, 19 places, LSP = +63.58, A/E = 1.42
3. Joseph O’Brien - 55 bets, 7 wins, 16 places, LSP = +43.00, A/E = 1.06
4. Ger Lyons - 123 bets, 20 wins, 22 places, LSP = +15.11, A/E = 1.04
5. Dermot Weld -138 bets, 37 wins, 30 places, LSP = +24.99, A/E = 0.99
6. Aidan O’Brien - 197 bets, 33 wins, 47 places, LSP = -63.15, A/E = 0.72
7. Jim Bolger - 154 bets, 12 wins, 29 places, LSP = -30.60, A/E = 0.61
8. Johnny Murtagh - 53 bets, 2 wins, 9 places, LSP = -43.40, A/E = 0.39
9. Mick Halford - 74 bets, 3 wins, 15 places, LSP = -64.10, A/E = 0.33
Top 5, especially 2, are worth following. Others should be avoided it seems. If you want to know about any other trainer not in list, let me know.
