Only the Los Angeles Dodgers and San Diego Padres' starters have recorded worse ERAs than Chicago's rotation among National League playoff contenders. Gore would bring a much-needed swing-and-miss element to the Cubs rotation, and would immediately slot in as the club's third starter behind Shota Imanaga and Matthew Boyd.

"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.

The MLB trade deadline is just a few days away, and the Chicago Cubs are reportedly pursuing starting pitching help.
