Fun with small samples: in nearly the same number of innings, Marquez's home ERA was 4.59 compared to 4.19 away from Coors Field, which makes sense. However, a 1.26 home WHIP versus 1.49 away is curious until you see Marquez's road BABIP was a bloated .331. Skills-wise, Marquez fanned more and walked fewer at home, though he predictably surrendered more homers in Coors. The message isn't Marquez is a better pitcher at home, but rather if he can improve his performance on the road, which he should, he can be a useful starter. In his favor is a low walk rate (2.7 BB/9) and a groundball tilt (45.2 percent) to help combat the long ball. Colorado did an excellent job managing his innings, limiting the righty to 29 starts spanning 162 frames. Marquez should eclipse that total in 2018, but not by much as the Rockies look to protect their still just 23-year-old arm. Read Past Outlooks
