Ironman Jon

[FantasticDan]

4yo by Mineshaft won easily first time out in February and toyed with the field before winning for fun in a 51K Allowance yesterday at AQU. An "impressive and intriguing NY Bred" (as NYRA's Jason Blewitt put it) to say the least..

Anyone know why he didn't start as a 2 or 3yo?
