Chicago Cubs: Is Tyler Chatwood a rotation option for 2018?

Up-and-down career

Chatwood broke into the majors in 2011 at the age of 21 with the Los Angeles Angels. In 27 games (25 starts), Chatwood went 6-11 with a 4.75 ERA. Along with that, the right-hander struck out just 74 batters in 142 innings pitched.

Following a rocky rookie campaign, Chatwood was traded to the Colorado Rockies. As a member of the 2012 Rockies, Chatwood appeared in just 19 games (12 starts), and logged just 64 2/3 innings pitched. In that time, Chatwood went 5-6 with a lofty 5.43 ERA and a 1.66 WHIP.

Despite having a horrid 2012 season, Chatwood rebounded nicely the following year. In 2013, Chatwood posted a career-best 3.15 ERA and eight wins in 20 starts for Colorado. The 23-year-old Chatwood also struck out 66 batters and walked 41 in 111 1/3 innings pitched. Even though he posted only a 1.61 strikeout-to-walk ratio, Chatwood logged a 142 ERA+ in 2013, the best mark of his career.

Injury plagued seasons

After starting just four games in 2014, Chatwood went down with an injury that would eventually require Tommy John surgery. The surgery kept Chatwood off a major league mound for the entirety of the 2015 season.
