Track and field is a revolving door of young and old. Last Saturday afternoon Hayward Field shook as Matthew Centrowitz, 21, a rising senior at Oregon, held off American record holder Bernard Lagat to win the 1,500 meters in 3:47.63. Centrowitz, the son of two-time Olympian Matt Centrowitz, still needs a qualifying time of 3:35.00 by Aug. 15 to run at Daegu and will pursue it in European meets. And rising Florida junior Tony McQuay, 21, took the 400 meters in 44.68 to stun struggling Olympic medalist Jeremy Wariner.
At the other end of the spectrum, shot-putter Adam Nelson, 35, winner of two Olympic medals, won with a throw of 72' 5¾", his longest since '08. A father of two with an M.B.A., Nelson says, "It's really about the passion, and I've found that again."
