Four years ago, Michael Phelps collected the second of his record haul of eight gold medals with one of the most tense and memorable races in Olympic history.
His Phelps's teammate on the 4x100 relay, anchor Jason Lezak, caught France's Alain Bernard in the final 50 meters and beat him to the wall by a fingertip. It was instant Olympic lore, enhanced by what was at stake.
While the stakes were not quite so high Sunday night at London's Aquatic Center, France exacted its revenge in similar fashion. And while the manner in which their swimmers might have imagined payback playing out probably involved catching Phelps or the veteran Lezak on the last leg, the reality was even more shocking:
They caught Ryan Lochte.
Specifically, it was Yannick Agnel who caught Lochte, the gold medalist in the 400 individual medley Sunday night and one of the marquee stars of the sport. He did so on the final leg, making up a 0.55-second deficit after three legs to overtake Lochte over the last 50 meters to claim gold -- and yes, revenge -- in an overall time of 3 minutes 9.93 seconds.
"I'm kinda bummed," said Lochte in the mixed zone afterward. "When we go up on the blocks, we want to win."
The US, which led after each of the first three legs, swum by Nathan Adrian, Phelps, and Cullen Jones, took silver (3:10.38). Russia won the bronze (3:11.41).
The medal is the 17th of Phelps's career, and his first silver, to go with 14 golds and two bronzes.

2:15 p.m. We've got the first bit of news from the Aquatic Centre, at which four swimming medals are at stake Sunday night.
Ryan Lochte and Michael Phelps will swim during the 4x100 meter relay tonight, along with teammates Cullen Jones and Nathan Adrian.
None of the four swam during qualifying earlier in the day. It was believed, though not certain, that Lochte and Phelps, who went head-to-head in the 400 individual medley Saturday night, would compete tonight, but the confirmation just came a few minutes ago.
The race will give Phelps a chance to collect his first medal of these Olympics and his 17th overall. Lochte will be going for his second medal in London after winning gold in the 400 IM while Phelps finished a stunning fourth.
Lezak, who anchored the US's gold-medal winning 4x100 relay in Beijing, isn't one of the four chosen for the final, but as one of the swimmers who participated in prelims, he will receive a medal should the US make the podium.
The other medal events tonight are the women's 100-meter butterfly, women's 400-meter freestyle, and men's 100-meter breaststroke.
