"The Cubs desperately want another starter at the deadline, targeting Mitch Keller of the Pirates, and would include outfield prospect Owen Caissie to make it work," Nightengale wrote on Sunday. Keller has previously been an All Star, and he would be a boost near the front of the Cubs' rotation.

Although it was expected they would trade him to free up payroll space, new reports suggest they might keep him. With the trade deadline approaching, this decision could impact the team's future.
