Miller, 35, appeared in 108 games for the Marlins in 2007 and '08, going 9-2 with a 3.90 ERA. He last pitched in the majors in 2010 with the Dodgers. In seven major league seasons, Miller went 24-14 with a 4.82 ERA.
Miller was perhaps best known for his tattoos. He had so many of them that in 2004 Major League Baseball required him to wear long sleeves after hitters complained his tattoos were a distraction to them.
Chris Coghlan says he'll be returning to Texas on Monday to be re-examined by Dr. Drew Dossett, a spine specialist. Coghlan has been on the disabled list since June 9 with what is being described as "right calf nerve irritation."
Coghlan has already visited Dossett once before and is continuing to rehab, but hasn't been cleared to resume baseball activities. He said his return status remains uncertain.
The 2009 Rookie of the Year for the Marlins was starting to show improvement at the plate when he landed on the DL. After a slow April in which he hit .180 and drove in only one run, Coghlan warmed up in May and June, hitting .338 with nine RBI.
"It involves the nerves," Coghlan said. "I thought I had blown out my calf. I didn't know what the heck it was."
