Shortstop Starlin Castro could be a long-term Chicago Cub soon.
The Cubs are discussing a contract extension with Castro that will run six or seven years, according to major-league sources.
The deal, sources said, also will include a club option for an additional year.
Talks continue to progress, and a deal could be reached early next week, if not sooner, sources said.
Castro, a two-time All-Star at 22, entered Friday night's play batting .276 with a .729 OPS, 12 home runs and 58 RBIs.
His deal would cover all four years of arbitration, plus two or three free agent years.
Castro, as a Super Two player, qualified for an extra year of arbitration.
