CHICAGO — First-time manager Rick Renteria’s challenge goes beyond trying to bring a winning team to Wrigley Field.

The development of young ballplayers has been labeled as one of his strengths.

And with Starlin Castro and Anthony Rizzo needing help, Renteria – former manager of the Portland Sea Dogs – has got lots of work ahead of him with the Chicago Cubs after being hired on Thursday.

Renteria is another unproven hired by team president Theo Epstein and the Cubs after the struggling organization was rebuffed by New York Yankees Manager Joe Girardi.

The Cubs are relying on Renteria to improve on a 127-197 record during Dale Sveum’s two years as manager. With 30 years of pro baseball experience, Renteria is the latest manager hoping to bring the Cubs their first World Series title since 1908.

The Cubs went 66-96 this season and finished in last place in the NL Central for the first time in seven years.
