Transgender University of Pennsylvania swimmer Lia Thomas was crushed twice in a women's swim meet by another transgender competitor who is transitioning from female to male - first in the 100-yard freestyle, where she placed fifth, and then again in the 400-yard freestyle relay.   

Competing against Ivy League rivals Dartmouth and Yale, Thomas won the first of her four races by just two seconds - one month after she shattered two women's records with a 38-second margin against her closest competitor. She also narrowly won the 500-yard freestyle by a second, with bystanders telling DailyMail.com that she seemed to be 'coasting' and 'barely trying'. 

But stunned parents at the meet held at UPenn's pool in Philadelphia gasped as Yale swimmer Iszac Henig easily beat out his opponents in the women's 100-yard freestyle with a time of 49.57 seconds. Thomas finished fifth with a time of 52.84 seconds. 

Henig, a 20-year-old from Palo Alto, California, has delayed hormone treatments to finish his career on Yale's women's team as he transitions from female to male. 

In the women's 400-yard freestyle relay, Henig again crushed Thomas and his other competitors, finishing in 50.45 seconds to power Yale to victory in the meet. Thomas finished her leg of the race in 51.94 seconds. 

Henig also finished first in the 50-yard freestyle in a time of 22.76. After the race, Henig, who has had surgery to remove his breasts, pulled down the top of his swimsuit, shocking some parents at the meet. 

'I wasn't prepared for that. Everything is messed up. I can't wrap my head around this. The NCAA needs to do something about this. They need to put science into the decision and discussion,' a UPenn parent, who wanted to remain anonymous, told DailyMail.com.
