Olympic Results 2012: Breaking Down Best Medal-Winning Performances from Day 15

The number of events has lessened considerably compared to earlier in the Games, but Day 15 of the London 2012 Olympics has certainly produced some great moments.

It has been a particularly big day for the United States and China atop the standings, but other countries have been able to have their day in the sun, too.

Some of the Olympics' marquee events took place on Saturday, and there were some exciting performances to witness. There is a lot to love about the Olympics, but watching the best athletes in the world come through when the pressure is at its highest point is truly special.

Here are the three top medal-winning performances from Day 15 of the Olympics, as the 2012 Summer Games wind to a close.

Mexico (Men's Soccer)

Brazil entered the men's soccer final as a heavy favorite to take gold, thanks to a star-studded roster featuring the likes of Neymar, Hulk, Marcelo and others.

Mexico looked impressive throughout the tournament and had a strong lineup in its own right, but few gave the Mexicans much of a chance.

They shocked Brazil by a score of 2-1, however, and stopped Brazil from winning its first Olympic gold.

Mexico took away Brazil's confidence from the very start, as veteran Oribe Peralta scored in the first minute of the match. Mexico held that lead until Peralta put it away in the 75th minute.

Hulk scored in stoppage time, and Brazil had a chance to tie it on an open header, but the ball sailed over the net, and Mexico preserved the victory.

The Mexicans have been edging closer to being an international power in recent years, and this win has to give their fans a lot of hope for the future.

Australia (Women's Basketball)

The Australian women's basketball team has lost to the United States in the gold-medal match in the past three Olympics, but a slip up in pool play this year meant that they had to deal with the Americans in the semis.

Team USA vanquished the Opals yet again, and Australia could have very easily pouted and put forth a poor effort in the bronze-medal game.

But the Australians decided to show up, play hard and ultimately win the game. Russia gave Australia all it could muster, but Australia had too much firepower, winning 83-74.

It should come as no surprise that veteran center Lauren Jackson led the way in what could conceivably be her final Olympics. Jackson paced the Aussies with 25 points and 11 rebounds as the Russians didn't have an answer inside.

After yet another frustrating performance against the United States, Australia's perseverance was very impressive.

United States (Women's 4x400-Meter Relay)

The women's 4x400-meter relay is an event that has been dominated by the United States over the years, and that domination continued on Saturday, as Team USA blew away the field to win gold.

The team of DeeDee Trotter, Allyson Felix, Francena McCorory and Sanya Richards-Ross was in control from the start and finished just shy of a world record. American women have had quite a haul on the track in London, and this team capped it.

Watching individual track events is exciting, but there is something special about watching a team get the job done in a relay. There are so many things that can go wrong, from dropping the baton to running into other runners, so having four women execute to perfection is no small feat.

Excellence on the track is nothing new for Team USA, but the women's roster in London may rival that of pretty much any other in recent memory.

The Americans may very well have had the four best overall runners in the race, and that isn't something that happens very often.
