DAEGU, South Korea - Fatigued, Allyson Felix faltered down the stretch in her bid for a fourth straight 200-meter world title.
Energized, LaShawn Merritt rallied on the last turn in the 1,600-meter relay to win the gold medal, avoiding an embarrassing loss.
It was that kind of night Friday for the United States at the world championships: highs (long jumper Dwight Phillips winning a fourth title) and lows (the mighty shot putters shut out of a medal). There was also Carmelita Jeter adding a silver medal in the 200 to her gold in the 100 earlier in the week.
