The Red Sox received Joe Kelly (along with Allen Craig) in 2014 after they traded John Lackey to the Cardinals. Even though expectations were low for Kelly entering the 2015 season, he mentioned his plans on winning the Cy Young back in February.
The RHP had the worst season of his career, posting a career-high 4.82 ERA. However, the sole highlight of his season came in August, when he had a stretch of 8-0 posting a 2.59 ERA. This was not the first time the pitcher had accomplished a record like that, since in 2013 he won eight consecutive decisions in ten starts.
