Trevor Story, Rockies ruin Zack Greinke's Diamondbacks debut

PHOENIX -- The Colorado Rockies put on an offensive clinic and laid waste to the highly anticipated debut of Zack Greinke on Opening Day as they defeated the Arizona Diamondbacks 10-5. Greinke allowed as many runs Monday night as he did in all of April last year, surrendering seven runs in four innings of work.

Turning point: Things unraveled for Greinke in the third when opposing pitcher Jorge De La Rosa came to the plate after a leadoff single from DJ LeMahieu. After two unsuccessful bunt attempts, De La Rosa sent a chopper arcing over the head of third baseman Jake Lamb for a single. The inning spiraled into oblivion thereafter; seven hits (two of them homers), a walk, six earned runs and 48,000 silent paying customers.

Story-book beginning: Rockies shortstop Trevor Story had quite a major league debut. The post-hype breakout candidate was hot this spring, and if Story and his natural opposite-field power are for real, the Rockies may have found a serviceable replacement at shortstop less than a year since parting ways with franchise cornerstone Troy Tulowitzki. Story became the first player in major league history to hit two home runs in an Opening Day debut, poking a Greinke fastball out to right field in the third inning and golfing a Greinke slider out to left field in the fourth.

Bright side for D-Backs: Though notably awful, Greinke’s outing is probably nothing more than a nauseating blip on what will otherwise be a fine season. There was some silver lining for Arizona. Utility man Chris Owings started in center field for injured star A.J. Pollock and scouts clocked Owings’ run times to first base at just less than four seconds. Those are 80-grade run times on the 20-80 scouting scale, clear evidence that Owings has more than enough speed to play center field (which, before Monday night, he hadn’t done since high school) and might be able to provide something approaching Pollock’s Gold Glove season of 2015.

What's next: Arizona hopes for a better result Tuesday as another of their splashy offseason acquisitions, Shelby Miller, takes the ball in opposition of Rockies righty Chad Bettis. Colorado hopes to continue an offensive onslaught that was spearheaded on Opening Day by Story, Gerardo Parra (three doubles), Nolan Arenado and Carlos Gonzalez (each 2-5 with a home run).
