The Cubs are aiming to upgrade their rotation this offseason, and they've often been connected in free-agent rumors to right-hander Alex Cobb, who played for Chicago manager Joe Maddon on the Rays.
According to NBC Sports Chicago's David Kaplan, however, Cobb has already rejected the Cubs' offer, valued at $42 million over three years.
Cobb, 30, went 12-10 with a 3.66 ERA in 29 starts with the Rays last year, his sixth in the big leagues. He's also been recently linked to another National League Central club, the Brewers.
The Cubs signed one of Cobb's former Rays teammates, Drew Smyly, to a two-year deal last month. While Smyly is unlikely to pitch in 2018 after undergoing Tommy John surgery last July, he touted a potential reunion with Cobb in Chicago.
"I think any team would be pumped to have Alex Cobb. I would love for him to sign with Chicago. [Since] I became a Ray, he's been one of my better friends. We just hit it off and connected. I know he's going through the free-agent process now. Who knows where he'll land? It's a pretty crazy game. I can only imagine how he feels -- I was a little overwhelmed and I was kind of at the bottom of the barrel in the free-agent market, and he can kind of pick and choose where he wants to go. I'm sure a lot of teams are fighting for him. Wherever he lands, he's definitely going to help that team out. I'll be anxious to see where all these pitchers sign in the next coming weeks."
