SAN FRANCISCO -- Edinson Volquez, who last month tossed the Marlins' sixth no-hitter in franchise history, was placed on the 10-day disabled list Friday with left knee tendinitis.
Still, the Marlins don't expect Volquez to miss his spot in the rotation because of the All-Star break. Miami manager Don Mattingly said the 34-year-old will start July 16 when the Dodgers visit Marlins Park.
"We're looking at Game 3 [of that series]," Mattingly said. "We want him to be able to throw a bullpen and make sure everything's going to be good. We'd feel more comfortable -- and he'd be more comfortable -- being able to throw that bullpen on Friday. He always throws it two days before."
Volquez -- Miami's Opening Day starter -- exited his Wednesday start after four innings. Initially, Mattingly wasn't sure if Volquez would land on the DL. He went on the DL in May with a blister.
In a corresponding roster move, the Marlins purchased the contract of Chris O'Grady from Triple-A New Orleans to start Saturday's game against the Giants. The game -- which will be O'Grady's MLB debut -- was Jeff Locke's spot in the rotation. The Marlins designated Locke for assignment Tuesday, a day after he allowed 11 runs in a loss to the Cardinals.
"Right now it's everything I expected and then some," O'Grady said Friday. "I can only imagine what it will be like 24 hours from now. No matter what happens, it's going to be great. ... It will be a dream come true."
O'Grady has a 3-5 record with a 3.29 ERA this season for New Orleans. He's started nine of his 12 games and pitched 54 2/3 innings.
Over his last five starts, O'Grady allowed five runs (three earned). News of his Triple-A success made its way to Mattingly, who called O'Grady the "right guy for the start" Saturday.
"He's a guy with good command and pretty good pitch ability," Mattingly said. "He's competitive. ... We'll have a good chance to see him tomorrow with everybody else."
O'Grady, who received news of his promotion Wednesday night, said his newfound ability to throw an elusive changeup has allowed him to take the next step.
"My cut fastball, which has always been great -- and now I have a changeup going in the opposite direction," O'Grady said. "It's just been all the difference."
