NL Central Notes: Brewers, Rodriguez, Cubs, Marmol

Yesterday, we learned that the Brewers offered a contract extension to Jean Segura about a month ago, but no deal is close between the two sides at this time.  The 23-year-old has just 81 big league games under his belt and there's not a great deal of precedent in place to work out a new deal as only two position players with less than one year of service (Evan Longoria and Salvador Perez) have inked extensions.  Still, Milwaukee would love to lock up their young standout to a team-friendly deal as the Cubs did earlier this week.  Here's more out of the NL Central..

• Today was Francisco Rodriguez's opt-out date with the Brewers and the club decided to call him up to the big league roster, tweets Jon Heyman of CBSSports.com.  Now that he has been promoted to the varsity squad, K-Rod's deal calls for him to earn roughly $2MM for the 2013 season.  Milwaukee had 30 days to evaluate Rodriguez before making their determination today.
• Despite his struggles, Carlos Marmol firmly denied a rumor that he wants out of Chicago in order to get a fresh start, writes Carrie Muskat of MLB.com.  “I’m not going nowhere,” Marmol said. “I’m very happy here. I can’t wait until they do something so I can stay here. I always talk about how I love Chicago, I love being here, I love my teammates, I love everybody here.”  The pitcher met with agent Paul Kinzer earlier today but Marmol says they weren't talking about moving on from the Cubs.  
• In his latest mailbag, a reader asks Paul Sullivan of the Chicago Tribune if the club could get Marmol back on track by moving him to the starting rotation.  Sullivan notes that the reliever began as a starter in 2006 and didn't succeed and opines that a trade is the only solution.
