Now that he’s healthy again, LaShawn Merritt of Suffolk is righting the ship for the U.S. track team at the 400-meter distance.

Days after winning the individual 400-meter world title, Merritt helped the 4×400-meter relay team rebound from its first Olympic loss since 1972. He ran the anchor leg in a strong win at the 14th International Association of Athletics Federations World Championships on Friday in Moscow.

The team, including David Verburg, Tony McQuay and Arman Hall, finished with a time of 2:58.71, well ahead of Jamaica, which had a second-place time of 2:59.88.

After re-aggravating a left hamstring injury at the 2012 London Olympic Games, Merritt was unable to run with the U.S. 4×400-meter relay team, which settled for silver.
