Breeders' Cup 2015 Results: Twitter Reacts to Thrilling Classic Race

American Pharoah capped off a legendary career on Saturday with a dominating victory at the Breeders' Cup Classic from Keeneland in Lexington, Kentucky.

Here is the replay of the race, where it is clearly apparent how much this horse means to those involved with the sport:

It was a wire-to-wire victory for Pharoah, breezing to a 6.5-length win. Here are the full results from the entire field:

Finish	Horse	Lengths Behind Winner
1	American Pharoah	-
2	Effinex	6.5
3	Honor Code	11
4	Keen Ice	12.5
5	Tonalist	12.5
6	Hard Aces	12.5
7	Frosted	12.5
8	Gleneagles	25.5
9	Smooth Roller	Scratched
10	Beholder	Scratched

It was horse racing's last big race of the season, and it was a sentimental one, too. The sport was saying goodbye to the Triple Crown and now Breeders' Cup victor, the first-ever Grand Slam winner in horse racing.

NBC Sports sent out this congratulatory tweet:

Not only was it history-making that American Pharoah won a Grand Slam, but he also set a new record at Keeneland, per WDRB's Eric Crawford:

After the race, those in attendance were given one last chance to show their appreciation for American Pharoah, as shown by the Champions Series:

Fresh off of a Travers Stakes loss at the end of August to fellow Breeders' Cup opponent Keen Ice, Pharoah was back with a vengeance and ended his career with a bang. 

For Sports Illustrated's Richard Deitsch, his authoritative win is deserving of an award:

It was a win fitting for such a champion as American Pharoah thrust horse racing back into the homes of sports fans around the world in 2015. Many took to Twitter to express their appreciation. 

USA Today Sports' Jeff Gluck, like many, was overcome seeing him finish his final race:

A man who has seen plenty of horses in his lifetime, trainer Johnny Murtagh knew he was watching a once-in-a-lifetime winner:

TVG's Nick Hines-Sarge was just as impressed:

So was NBC's Bruce Beck:

Former NHL goaltender Kevin Weekes kept it short and sweet:

As did former NFL linebacker Lance Briggs:

"

American Pharoah is the .

Winning a ninth race in 11 tries, American Pharoah won an estimated $2.75 million on his final go around. That's not too shabby a pay day for a horse that has now earned around $8.65 million in his career, per Associated Press Sports.

For one of the most dominant horses the sport has ever seen, American Pharoah certainly belongs in the upper echelon of horse racing's best, and he gave spectators one final glimpse of his sheer power and speed on Saturday afternoon in Kentucky.
