Cubs Open to Keeping or Trading Pitcher Marcus Stroman, Unlikely to Extend Before Deadline

Sources say the Chicago Cubs are unlikely to extend pitcher Marcus Stroman's contract before the trade deadline.
The Cubs want to see how they play over the next month before deciding whether to buy or sell at the deadline.
Stroman can opt out of his contract after this season and may be traded or remain a key player for the Cubs.
Stroman has expressed interest in possibly re-signing with the Cubs in free agency.
The Cubs could revisit extending Stroman in September if they don't trade him this summer.
