Tyler Chatwood: Starting Pitcher Points: 69 Highest Rank: 9 Lowest:15

Chatwood was initially acquired from the Angels for Chris Iannetta in 2011, the same season he made his major league debut. He has been very solid for the Rockies ever since but has struggled to stay healthy. He started only four games in 2014 before suffering an UCL injury requiring Tommy John surgery. It was the second time Chatwood underwent the major surgery, the first being as a 16 year-old high school student. After missing the entire 2015 season, Chatwood was eager to return to the rotation in 2016 and had a very successful season.

Over 158 innings, Chatwood boasted an ERA of 3.87, going 12-9 in 27 starts. Chatwood’s elbow seems to be a non-problem with a quick stint on the 15-day DL secondary to back pain being his only injury in 2016.

Chatwood, more than any other Rockies’ pitcher, showed a dramatic split at Coors Field. In 14 starts at home, Chatwood struggled his way to a 6.12 ERA and a WHIP of 1.641. Chatwood dominated on the road, owning a miniscule ERA of 1.69 and a WHIP of 1.13. The difference came entirely from hits as Chatwood had nearly identical BB/9, K/9 and K:BB stats regardless of where the start was located.

Chatwood is one of the most volatile pitchers in the 2017 rotation, secondary to his injury history as well as the dramatic splits in 2016. Hopefully he will be able to normalize his performance at Coors Field while staying healthy this season.
