Martin Prado has a Grade 1 right hamstring strain and a slight upper right calf strain, and the Marlins' third baseman does not anticipate being ready for Opening Day.

As discouraged as Prado is about not being ready for the regular season, he's also relieved by the results of his MRI, because he feared the worst.

"Best scenario now, is not Opening Day," Prado said on Sunday morning. "I'm just hoping we can get fixed and not worry about feeling this during the regular season."

Prado was injured on Wednesday in Venezuela's 4-2 loss to Team USA in the World Baseball Classic at Petco Park in San Diego. On Saturday, he had an MRI taken in South Florida.

"I was worried, yeah," Prado said. "I didn't know what it was. I didn't know exactly what was going on with my leg. After I talked to the doctor, I was just concerned and disappointed that I let my teammates down. I let the Marlins down because I was not able to come back here healthy."

Playing for his country, Prado was running to first base after hitting a ground ball, but he pulled up as he approached the bag. The Venezuelan medical staff tended to him as he left the game.
