5 starting pitchers the Cubs probably regret not signing in the offseason

3. Zach Eflin

Who else but the Tampa Bay Rays could have transformed Zach Eflin from an unreliable back-of-the-rotation guy in Philadelphia to a solid middle-of-the-rotation arm. Although he still struggles to keep the ball in the yard at times, having given up 8 home runs on the year so far, Eflin is providing better-than-average value in the Rays rotation.

With a 3.45 ERA and a WHIP sitting at 1.00, the 29-year-old is earning his $11 million paycheck this year. Which by the way makes him the highest-paid player on the Rays this year even though that is a very team-friendly contract. But without a proven track record, I can understand why the Cubs passed on Eflin.
