Usain Bolt on cruise control in 100-meter heat at world championships

After Day 1 in Moscow, Usain Bolt is on track to recapture the 100-meter gold medal he lost at the last world championships. 

Even if a false start in Bolt's heat was reminiscent of the one that disqualified him in the 2011 final, it was the runner next to him who was sent packing Saturday. On the second attempt, Bolt cruised to a time of 10.07 seconds. Americans Mike Rodgers (9.98) and Justin Gatlin (9.99) had the top times.

In the men's 10,000, double Olympic long-distance champion Mo Farah fought off Ibrahim Jeilan over the last 150 meters, winning in 27 minutes, 21.72 seconds. Jeilan was timed in 27:22.23.

Defending champion Edna Kiplagat won the women's marathon in 2 hours, 25 minutes, 44 seconds. She beat Valeria Straneo by 14 seconds. In sweltering heat only 46 of 70 entrants finished.

In the decathlon, Olympic champion Ashton Eaton led after five events -- 4,502-4,493 over U.S. teammate Gunnar Nixon.
