The 23-year-old was a centerpiece of a trade made in July 2012 that sent Anibal Sanchez and Omar Infante to the Tigers.
At the time, the Marlins were hopeful Turner would be a big part of their rotation for years to come. It didn't work out.
Miami's front office has shown it will be patient to a point. But if something makes sense, the club will react and turn the page, if necessary. Last week, the Marlins showed that by trading prospects Jake Marisnick and Colin Moran to the Astros for right-hander Jarred Cosart and infielder Enrique Hernandez.
"Bottom line is we're trying to win games here," president of baseball operations Michael Hill said. "We're trying to make decisions that will allow us to win games, not only now but into the future."
Marisnick, an athletic outfielder, was a big piece of the November 2012 trade with the Blue Jays. And Moran, the sixth overall pick in the 2013 First-Year Player Draft, was initially projected as the third baseman of the future.
Marisnick, however, was blocked by Christian Yelich, Marcell Ozuna and Giancarlo Stanton in the outfield. Moran wasn't projected to be part of the plans in 2015, either. The team hopes to sign third baseman Casey McGehee, who is arbitration-eligible next year, to an extension.
"Every circumstance is different," Hill said. "If you don't feel like you have a chance to win, then to be reckless with your inventory is just reckless. But if you have a plan and you're trying to execute a plan, we work through a myriad of scenarios with this ballclub and what we want to get accomplished."
