Quintero, who had his 11-game hitting streak snapped in Monday's 4-3 loss to the Cubs, underwent an MRI on his knees and back on Tuesday and was given a green light to play. He said the tests showed that a disk in his back was inflamed, and he's scheduled to have a cortisone injection after Wednesday's game.
"Everything is fine," said Quintero, typically downplaying his lingering health concerns.
Quintero entered Tuesday having hit safely in 16 of his past 18 games with an at-bat. It would have been difficult to keep him out of the starting lineup, considering he's had a terrific working relationship the past two years with starter Brett Myers.
