It was something that his father, Gary Matthews Sr., never did in his 16-year big league career.
"So I now have something else on him now," Matthews said with a smile. "I definitely expected to have a good year, but it's been so much more than I ever thought it would be. To go out and have a day like this one is just the icing on the cake. The only thing that would make it better is having my family here, but I'm sure they're watching at home on television."
Matthews Jr. is hitting .314 with 18 homers this season and made his first All-Star appearance after an excellent first half.
His accomplishments thus far have certainly made his father, currently a coach for the Chicago Cubs, very proud.
"I'm proud of him for doing the things he has and the way he's played for them," the elder Matthews said. "He has a 'never give up' attitude. Any time you hit for the cycle -- and more importantly, win -- it makes it sweet."
Matthews became the 14th Major Leaguer to hit for the cycle in "natural order," singling in the first inning, doubling in the second, tripling in the fourth and homering in the sixth. He is also the fourth Major Leaguer to hit for the cycle this season.
Kansas City Royals Esteban German (.481, five doubles and eight RBIs) and Ryan Shealy (.318, three homers and 12 RBIs) were also up for the award.
