Wariner failed to improve on his Drake result of 45.35, where he lost to Santos, by losing to Bingham in an even worse time of 45.39
Meanwhile, Merritt was already at 44-mid in Shanghai, where James was already at 44-flat.
Not only is Wariner not showing improvement, he's not even winning.
I'm calling it official now--Wariner is done. Finished in the 400m. He's had more than enough time, and not enough time remains.
