Entry lists for the Rabat Diamond League meet are up, and they include this fascinating matchup between Olympic champions. Who do you think has the advantage? Miller-Uibo's PR is a full second faster, but as we all know, Semenya appears to always put forth the minimum effort necessary to win. The way she runs this race should be a good indicator of whether or not she actually can challenge the 800 record should she attempt it. It's also interesting to see her in a situation where she is likely the underdog, given all the controversy. Also, we shouldn't forget about Quanera Hayes in this one, who has the fastest SB in the field.
Prediction: Miller-Uibo 49.5, Semenya 49.6, Hayes also sub-50.
