Flying yes. And it's not just Yearwood who is denying girls the chance to compete fairly & win college scholarships. Another male now competing & dominating in Connecticut girls track is Terry Miller, who went from running on the boys team one semester to running on the girls team the next without any observable transition other than hair extensions.
In the CT state championships in June, Miller & Yearwood dominated, taking 1st & 2nd place in their respective events as well as overall. This meant that at the final awards ceremony, instead of three girl state champions on one podium & three boy state champions on the other, there were five male state champions & only one female. So in a very short time of two years, girls in CT track have been all but entirely eclipsed.
I've read in the local press that high school girl runners in CT are now hurriedly scrambling to switch to different track & field events where boys will be less likely to infiltrate & defeat girls so handily. Some girls are abandoning track & field entirely, again seeking sports less likely to be so easily infiltrated & dominated by male colonizers.
Sorry to link to a Daily Mail article, but it contains illuminating videos showing Miller & Yearwood in action that I couldn't copy from elsewhere.
