Grading the Pirates’ season: Rotation

The Pirates used only seven starting pitchers in 2017. I’ll list them all here, even though Steven Brault made more relief appearances than starts.

Gerrit Cole: 33 starts, 12-12, 4.26 ERA, 3.81 xFIP, 3.1 fWAR
Ivan Nova: 31 starts, 11-14, 4.14 ERA, 4.19 xFIP, 1.9 fWAR
Chad Kuhl: 31 starts, 8-11, 4.35 ERA, 4.61 xFIP, 1.9 fWAR
Trevor Williams: 25 starts, 7-9, 401 ERA, 4.49 xFIP, 2.2 fWAR
Jameson Taillon, 25 starts, 8-7, 4.44 ERA, 3.89 xFIP, 2.9 fWAR
Tyler Glasnow, 13 starts, 2-7, 7.69 ERA, 5.64 xFIP, -0.6 fWAR
Steven Brault, 4 starts, 1-0-1, 4.67 ERA, 5.58 xFIP, 0.2 fWAR
