Carlos Marmol's agent, Paul Kinzer, told CBS Sports' Jon Heyman via text message that he's not sure if his client will pitch again this season. Marmol, who signed a minor league deal with the Reds in late May, was placed on the restricted list at Triple-A Louisville last week after leaving the team without permission. "A lot has happened in the past year and he decided to go to the Dominican," wrote Kinzer. "We aren't sure when or if he will return this year." Kinzer didn't specify why Marmol left the team, but he indicated that there were "personal" reasons behind it and that he wants to "take a mental break."
