If nothing else, Trevor Story will have something to tell his grandkids about.
The Rockies rookie shortstop hit a pair of home runs against Diamondbacks starter Zack Greinke in his major league debut to propel the Rockies to a 10-5 win.
Story was 2-for-6 in the Rockies' opener with the two home runs and four runs driven in. He was hardly alone in providing the Rockies' offensive output as Carlos Gonzalez and Nolan Arenado each contributed a home run and Gerardo Parra added three doubles in his Rockies debut.
Arizona got on the board first in the bottom of the second when a two-out RBI single from Greinke, of all people, brought home David Peralta, giving the Diamondbacks a 1-0 lead.
However, the Rockies answered in a big way in the third. DJ LeMahieu and Jorge De La Rosa opened the inning with back-to-back singles before Charlie Blackmon tied the game with an RBI double, setting the stage for Story to give the Rockies the lead with his first career home run, a three-run shot to the opposite field. Gonzalez followed Story's homer with an absolute bullet that cleared the pool beyond the right-center field fence, extending the Colorado lead to 5-1. The Rockies tacked on a sixth run in the inning when Parra scored on a LeMahieu base hit.
One home run against Greinke was not enough for Story as he came to bat in the fourth and hit an absolute no-doubter to left, becoming the first Rockies player (and fifth player in MLB history) to hit two home runs in his big league debut.
Greinke did not come out to the mound for the fifth, having allowed seven earned runs on nine hits in his four innings of work, walking one and striking out two.
Arizona did not go quietly, though, as they clawed back a pair of runs in the fourth on a home run from Jake Lamb and got two more in the fifth on a two-out, two-run single from Yasmany Tomas to cut the Rockies' lead to 7-5.
Tomas' single chased De La Rosa from the game; he ended the night with 4⅔ innings, allowing five runs on eight hits with a pair of walks and eight strikeouts, failing to qualify for a win. However, four Rockies relievers combined to pitch 4⅓ shutout innings, holding the Diamondbacks at bat.
The bullpens kept the score quiet from the fifth until the eighth when the Rockies added some insurance on a three-run home run from Nolan Arenado against Diamondbacks reliever Silvino Bracho to extend the lead to a 10-5 margin.
The Rockies will look to take a series win tomorrow with Chad Bettis on the mound against Arizona's Shelby Miller.
