BEIJING -- Usain Bolt did Sunday night what Usain Bolt does best, winning the men's 100 meters at the 2015 world track and field championships, crossing just one-hundredth of a second in front of Justin Gatlin.

This was not, for the record, a morality play. This was, simply, an excellent race.

For any and all worried about the future of track and field or who believed that the men's 100 final at the Bird's Nest made for a referendum on sport or life itself, be assured -- the sun was going to come up Monday morning all over the world, whether Bolt or Gatlin prevailed. All is not right, or wrong, because of one-hundredth of a second.

And now we all have the delicious anticipation of a year-long build-up to the men's 100 at the Rio 2016 Olympics. Not to mention the 200 here later this week.

This is all to the good for track and field. Indeed, it's awesome. The race Sunday drew worldwide attention.

As Gatlin's agent, Renaldo Nehemiah, would say late Sunday night, "It's what our sport sorely needs. A sport needs a rivalry. A photo finish like that is great for the sport.

"It elevates Bolt even more," Nehemiah said, adding with emphasis, "It elevates Gatlin even more."
