The men's 200 free will be a "mouth watering"

(sorry about that) affair. According to Billy Hill, the 400m freestyle winner Sun Yang is an 11-10 chance, as against Agnel's 2-1 and Lochte's 5-2. The really interesting thing about the clash is the path taken into the race by the swimmers. Yang has to step back from the 400, while Agnel and Lochte will step up from the 100 relay. I think Lochte showed in the relay that he's more a 400 man. He was run down by Agnel in the relay but was outstanding in the 400 IM. Maybe the 200 will suit him tonight, but I'm not too sure about Yang. So for what it's worth, I think Agnel is easily the best of the three at 100m, but can he match it with the "stayers" over a grueling 200? I'd be prepared to take the punt and say yes.
Out on a limb time. Yannick Agnel.
