The Ducks came up big this evening, with both Makenzie Dunmore and Elexis Guster advancing to the Semi-Final round of the 400 meters at the USATF Championships. Makenzie just continues to get faster as the season progresses. She came to Oregon all the way from Georgia, where her best high school time was an eye-popping 52.52 seconds. In a season of new Personal Bests, she got another today with an impressive 51.42. Her teammate, Guster, was just slightly off that mark, with her own 51.56. Interestingly, Dunmore was not a member of the Women's 4 X 400 team that broke the all time Collegiate Record at the NCAA championships. I think it is safe to say that, with Guster graduating, Dunmore is going to fill those shoes nicely next season.
