Sporting Kansas City took the final step toward retaining the core of its club on Monday, when it locked up midfielders Soni Mustivar and Paulo Nagamura to new contracts.
The terms of the two deals were not disclosed.
After re-signing the two midfielders, Sporting KC is set to return all 13 players who appeared in at least 17 games last season. It has also added attacking options Justin Mapp and Brad Davis during the offseason.
Mustivar, a defensive midfielder and Haiti national team player, started 20 games last year, his first MLS season. His insertion into the starting lineup revitalized a Sporting KC defense.
