Sean Marshall cannot pitch in Colorado. Career numbers at Coors: 5 G, 2 GS, 8.1 IP, 16 H, 3 BB, 11 ER, 11.88 ERA, 2.28 WHIP He had a "meh" start in his first appearance at Coors (5 IP 3 R, 6 H, 2 BB), and since then his other 4 appearances (including another start last year) 3.1 IP 8 ER, 10 H, 1 BB, 21.60 ERA, 3.55 WHIP. His breaking ball just doesn't break here. No excuses for giving up 5 runs in an inning that eventually plated 12 but still.
