Cubs shortstop Starlin Castro is expected to sign a new seven-year, $60 million contract as early as Tuesday that would lock the 22-year-old up as a key part of the team's future under Theo Epstein.
Sources confirmed Monday that Castro, already a two-time All-Star in only his third major league season, will likely make the deal final by Tuesday.
The Cubs and Castro had acknowledged that a deal was in the works, but indications are that the final details were worked out Monday.
It is said to call for a seven-year deal at $59 million with an eighth year club option containing a $1 million buyout. The deal is not believed to contain no-trade provisions.
