Have you guys read the selection criteria, only first and second matter coming third and fourth mean nothing. The selection committee will go back and look at the times Milburn and Wroe have run and pick from there, coming third does not = a single spot. Have a look at the times and the A qualifiers each has done.
400m
A (45.65) 44.86 Ben Offereins (W) Sydney AUS 27/02/10
[45.32 Offereins (W) Canberra AUS 30/01/10]
[45.53 Offereins (W) Perth AUS 15/01/10]
45.28 John Steffensen (N) Rome ITA 10/07/09
[45.37 Steffensen (N) Berlin GER 18/08/09]
45.31 Sean Wroe (V) Berlin GER 18/08/09
[45.40 Wroe (V) Sydney AUS 27/02/10]
[45.63 Wroe (V) London GBR 25/07/09]
45.56 Joel Milburn (N) Berlin GER 18/08/09
Based on performance I would pick Wroe ahead of Milburn and I think the selectors will do the same, nothing to do with Hollingsworth.
