Outfielder Justin Ruggiano said he had an MRI yesterday on his sore lower back and is waiting for the results.
Ruggiano, who came into camp as the front runner to start in center field, said the back was still tight today.

The Marlins open their Grapefruit League action on Saturday. Now, Gorkys Hernandez and Bryan Petersen figure to get action in center field along with prospects such as Christian Yelich.
Hernandez led the Venezuelan Winter League with a .367 batting average in 226 at-bats. He batted .212 with three home runs and five stolen bases in 45 games for the Marlins after being traded by Pittsburgh for Gaby Sanchez.
“This is a really, really big camp,” said Hernandez, who is out of options.
Hernandez said has felt more comfortable since making a mental adjustment to his appraoch when batting.
“When I get to home plate I know exactly what I have to do, I am focused for one pitch. That’s what I did in Venezuela and it was working for me,” he said.
