Incoming freshman Shayla Sanders (Lauderdale Lakes, Fla.) brought home the Gold as a member of the U.S. women’s 4x100-meter relay on the fifth day of the 2012 IAAF World Junior Track & Field Championships at Montjuïc Olympic Stadium.

Sanders, the Gatorade Florida Girls’ Track and Field Athlete of the Year, ran the anchor leg of the race and crossed the finish in a world-junior-leading 43.89.

The Red, White and Blue bested their semifinal time of 43.95 to help the U.S. women win their fifth straight gold medal and 12th medal out of 14 possible in World Junior Championships history.

Incoming freshman Arman Hall (Pembroke Pines, Fla.), who already captured silver in the men’s 400 meters Thursday, ran the anchor leg for the U.S. men’s 4x400-meter relay in the heats of the event on Saturday.

Hall and the men’s 4x400-meter relay won their heat and finished first overall in 3:06.26, a new season’s best, and advanced to Sunday’s final at 2:10 p.m. ET. The U.S. men’s 4x400 has won the last five and all but two golds in World Junior Championships history.

Incoming freshman Robin Reynolds (Miami, Fla.) will participate in a runoff as a member of the women’s 4x400-meter relay. The U.S. women were originally named the winners of the first heat in 3:34.12 and then were disqualified and called for a violation of IAAF rule 170.7 (exchanging outside of zone), as were the Romanian women.

Both teams filed a protest because the track officials placed the second-leg runners, which was Reynolds for the U.S., in the wrong position, near the end of the exchange zone.

After both teams’ protests were denied, both the U.S. and Romanian squads appealed their decision and the jury offered them both an opportunity for a rerun. Romania rejected the offer, but the U.S. will go ahead with the race that is slated for 5 a.m. ET. Should the U.S. run 3:39.44, they will advance to Sunday’s final at 1:45 p.m. ET.

Sunday is the final day of competition at the World Junior Championships in Barcelona. Montjuïc Olympic Stadium in Barcelona was the site of the 1992 Olympic Games, where Team USA brought home 32 medals in track & field, the second-most in American history.
