Was Greinke's poor performance due to illness?

By the fourth inning of the Arizona Diamondbacks' 10-5 Opening Day loss to the Colorado Rockies on Monday night, some D-backs fans were in full panic mode.

Zack Greinke, aka the man the D-backs signed to a $206 million contract in December, was getting shelled.

The 32-year-old allowed seven runs in a game for the first time in four years and three home runs in a game for the first time in seven seasons. Trevor Story, who was playing in his first-ever Major League Baseball game, hit two dingers off last year's MLB ERA leader.

But for those fans who think the D-backs' mega investment in Greinke is already a bust, consider this from MLB insider Ken Rosenthal.

If true, credit to Greinke for toughing it out despite being under the weather. He also drove in the D-backs' first run of the season on an infield single in the second inning.

Also, remember that Greinke had a stellar spring: He posted a 1.88 ERA in 14 1/3 innings pitched.

Feel better, D-backs fans? Well, regardless, let's hope Greinke's feeling better in time for his next start, which comes Saturday at home against the Chicago Cubs.
