Her best outing came in the hurdlers, where her 14.68 mark in the 100mH gave her 884 points. She also landed a solid mark in the long jump at 5.11m and went 1.55m in the high jump. Her second-place effort in the 800m at 2:22.35 also gave her 792 points. Lailah Green was second with 2,731 points and Gabrielle Davis was third with 2,632.

Pentathlon 13yo Boys: Sugar Land, Houston-based athlete Graylen Houston landed a big win after five events, totaling 2,584 points.

Day 2 of the AAU Junior Olympic Games will bring more race walk finals in the older age groups -- 13 yo to 17-18 -- while the multis will finish up their competitions across the board. In the women's 17-18 heptathlon, Parkview Baptist (LA) graduate Ariel Pedigo is aiming for 5,500 points as she looks to finish her high school career with a top 5 performance all-time in high school history. The decathlon features four athletes within 150 points of one another on the final day of action. For coverage of the AAU Junior Olympics, MileSplit and FloTrack will have live streaming video of the event.
