Though the Cubs just won their first World Series in 108 years, there is still a glaring weakness on the team; back-end starters.

Jon Lester, Kyle Hendricks and Jake Arrieta have been impressive the past two seasons, but after that, the back-end of the rotation is a liability.

Former San Diego SP Tyson Ross would make sense for the Cubs here.

Ross is coming off of a tough season, pitching only 5.1 innings, while battling injuries throughout the season. Ross had to undergo surgery for thoracic outlet syndrome, which happens when nerves or blood vessels are compressed. His expected recovery time is between February and April.

Ross would be a very cheap buy and a low-risk, high-reward kind of player. Signing him to a one year prove-it contract would make sense.

The Cubs would hope that he could return to his previous form, posting a 3.03 ERA across 64 starts from 2014-2015.

The Cubs are in dire need of a fifth starter, and Ross could just be their solution.
