A Bolt of lightning

In perhaps the best Olympic performance since Michael Phelps swam to eight gold medals the week before, Jamaica’s Usain Bolt bolted his way to history in the 100- and 200-meter sprints, setting new world records in each event. After dominating the 100-meter race earlier in the week with a world-record time of 9.69 seconds his encore was even more impressive. Absolutely burning up the track, Bolt beat former 200-meter world-record holder Michael Johnson’s record by turning in a time of 19.30. He is the first man since Carl Lewis of the United States to sweep the two events.

Griffey makes history

For the first time since 1999, Ken Griffey Jr. hit a home run for an American League team. The blast that came against his former team, the Seattle Mariners, tied him for fifth all-time in that category with 609 career jacks. After being traded to the Reds, Griffey endured several injury-plagued seasons that may have kept him from becoming the greatest home-run hitter ever.
