PHOENIX -- Opening day was a memorable one for the Rockies on Monday.
Rookie shortstop Trevor Story became the first player to hit two home runs in his first major league game on opening day as the Rockies opened the season with a 10-5 win over the Arizona Diamondbacks at Chase Field.
Story hit a three-run homer off the Diamondbacks' Zack Greinke, who had won his past six starts at Chase Field, in the third inning. Story hit another homer in the fourth inning.
Story became only the sixth player in major league history to hit two home runs in his debut. He also became only the third player to hit two homers off Greinke, who was making his Arizona debut, in the same game.
The Rockies have two more games against the Diamondbacks before returning to Denver for their home opener against the San Diego Padres on Friday afternoon.
