The story of men's sprints this year reads pretty much the way it's read for the past few years, at least in the short sprints, as Usain Bolt again dominated the 100- and 200-meter events. Bolt posted his best times at the World Championships, where he won the 100 in 9.77 seconds and the 200 in a world-leading 19.66. He also anchored Jamaica's victorious 4 x 100-meter relay squad and had three of the world's top five times. Tyson Gay posted the best 100-meter time of 2013, winning the U.S. Championships in 9.75 seconds, but he failed a drug test shortly afterward, ending his season and making his world-leading time suspect.
Justin Gatlin had another solid year at age 31, running the world's fifth-best time of 9.85 while earning silver medals in the 100 and the 4 x 100 in Moscow. Gatlin also won three Diamond League races and the overall season title. Nesta Carter and Asafa Powell - another runner who was sidelined by a positive drug test - each posted a top-10 time in 2013, while Carter took the World Championship bronze medal.
Bolt owned three of the year's top four 200-meter times. Gay was third after running 19.74 at the U.S. Championships. Warren Weir tied Bolt for fourth by running 19.79 twice, including his silver medal performance at the World Championships. American Curtis Mitchell gained the bronze medal in Moscow. Weir had five times in the world's top 10, while Isiah Young was seventh overall. Weir won three Diamond League 200-meter races and earned the season championship.
LaShawn Merritt and Kirani James dominated the 400 this year, with Merritt earning the biggest prizes. The pair co-owned the world top 10 list, with Merritt holding six spots. Merritt ran a world-leading 43.74 in the Moscow final, which was James' low point of the year as he faded to seventh. Tony McQuay took the silver medal in Moscow while Luguelin Santos earned the bronze. McQuay then teamed with Merritt to lead the U.S. to a decisive victory in the World Championship 4 x 400-meter relay final. James ran a season-best 43.96 in Paris in July to finish second on the 2013 list. Fittingly, Merritt and James won three Diamond League races apiece, but 2013 was Merritt's year. He won the Diamond Race final in Zurich and captured the overall championship.
