AT Doncaster the big one, the Group 1 St Leger, is over an extended 1m6f at 3.35pm.
Logician is a strong favourite and rightly so on form, plus he has the added advantage of being in the care of Johnny G Gosden.
The main man has landed the feature four times with Masked Marvel, Arctic Cosmos, Lucarno and Shantou.
Unbeaten, Logician powered to a near two length success in the Group 2 Voltigeur at York last time, and the winning margin could easily have been extended.
Stamina should be no issue and he could be a proper top class performer in 2020. He has to be a Nap!
