The three errors tied the club record for the most by any player in a game.
"It's one of those games where it kind of got away from me, but today's a new day," said Dominguez, who also drove in three runs. "I'll try to move on from it and learn from it and just go on."
Dominguez entered Thursday leading all Major League third basemen with a .990 fielding percentage. Astros manager Bo Porter, who was with the Marlins when Dominguez was beginning his professional career in Florida, has no doubt Dominguez will rebound.
"I was joking with Matty," Porter said. "I told him when I pulled out of the parking garage last night to drive home that it was snowing outside. I told him the odds of me pulling out of the parking garage and it snowing are just as good as the odds of you making three errors in one game. It was part of the game and it can happen to the best of them. It's a prime example of no matter how good you are, you can make errors."
