Some links from baseball's Central Divisions for your Sunday reading…
- New Astros general manager Jeff Luhnow has the right outlook, but very few pieces to work with, writes Jon Heyman of CBS Sports. One scout told Heyman that aside from Carlos Lee, only two players in the Astros' projected lineup have a chance to be even league-average hitters: Jason Castro and Chris Johnson.
- Corey Hart has torn cartilage in his knee that will require arthroscopic surgery and sideline him for three-to-four weeks, writes Tom Haudricourt of the Milwaukee Journal-Sentinel. Brewers manager Ron Roenicke said they won't rush Hart back like they did from an oblique injury that cost him his 2011 Spring Training, and that Hart will likely open the season on the disabled list.
- MLBPA executive director Michael Weiner told Haudricourt that the leak in Ryan Braun's positive drug test was an isolated, case-specific incident and that the process doesn't have a confidentiality problem.
- Joel Zumaya has opted for Tommy John surgery, writes MLB.com's Rhett Bollinger. Dr James Andrews will perform the operation at the end of March, and the Twins have yet to decide if they'll place Zumaya on the 60-day DL or release him, assistant GM Rob Antony told Bollinger.
