Cubs star Stroman pushing for extension as trade deadline looms; Front office remains silent

Marcus Stroman seeks a long-term contract with the Chicago Cubs but the team has shown no interest in negotiating.
Stroman and his agent have approached the Cubs multiple times about an extension but the team has not engaged in any talks.
Stroman has publicly expressed his desire to remain with the Cubs long-term but the feeling is not mutual based on the team's lack of response.
With an opt-out clause after this season, Stroman could become a free agent if the Cubs don't come to the table.
The Cubs' history of trading impending free agents who can't reach a deal suggests Stroman may be wearing another uniform soon if something doesn't change.
