Hamilton hit four home runs and a double in leading the Rangers to a 10-3 victory over the Orioles. When it was over, his teammates were in awe of what Hamilton had accomplished.
"The best individual performance I have ever seen," infielder Michael Young said in the visiting clubhouse. "I've never seen anything like. It was fun to be a part of. He's an incredible player."
"What a night. ... Amazing," manager Ron Washington said. "A perfect night for Hamilton and a perfect night for the Texas Rangers."
Hamilton's night has earned him a Greatness in Baseball Yearly Award for the MLB Hitting Performance of the Year.
"Obviously, other than the World Series, it's the highlight of my big league career," Hamilton said afterward. "I never hit three before in a game. When I did that, it was like what a blessing. To hit four is an awesome feeling."
Hamilton was the 16th player in Major League history to hit four home runs and the seventh to hit five extra-base hits. The 18 total bases set an American League record.
"You don't go out and try to do that," Hamilton said. "You just try to do the best you can, and if you break a record, great. You don't try to do that, you try to be the best player you can be for yourself and your team."
