According to two sources close to Jayson Stark of ESPN.com, the Chicago Cubs and Washington Nationals are no longer in the running for pitcher Brandon Webb. Webb is now choosing between the Texas Rangers and a mystery team from the National League Central. Sources close to FOXSports’ Ken Rosenthal say the Reds are the principal challengers to the Rangers.

Jerry Crasnick of ESPN was the first to report an interest by the mystery team last week.

One source says that Webb is “closing in” on the decision, and he’s considering offers from both remaining teams.

Webb is seeking a one-year deal with a significant guarantee plus incentives. He’d like to build value in 2011 with the hopes of securing a multi-year deal after the season.

The identified NL Central has not been confirmed. The Milwaukee Brewers are the only team to have denied any interest in the right-hander. Stark speculates that the St. Louis Cardinals or the Pittsburgh Pirates as the only logical candidates for Webb’s services.
