Quantrill is coming off a strong start at Philadelphia, where he allowed one run on four hits and two walks with one strikeout over six innings. It was the right-hander’s second consecutive quality start and the first time he allowed three or fewer runs this season. He’s pitched against the Mariners four times (three starts), going 0-1 with a 5.65 ERA. Quantrill is still trying to find his footing at Coors Field, where he is 0-2 with a 6.20 ERA in six games (three starts).

Kirby has faced Colorado once in his career, earning the victory and allowing two runs on 6 1/3 innings. He’s never pitched at Coors Field. Last Monday, he notched a win over Cincinnati, allowing two runs on five hits and no walks while striking out six in six innings.

Lambert will make his first start this season, replacing left-hander Kyle Freeland in the rotation. Freeland went on the 15-day injured list Friday with a left elbow strain. Lambert was reliable in his role as Colorado’s long reliever. He has never faced Seattle.

Hancock is facing the Rockies for the first time. In his last start, Hancock lost to the Cubs but surrendered just two runs on four hits over six innings. He issued no walks and struck out four during his first quality start of the season. It significantly improved over his previous outing vs. Milwaukee when he got rocked for eight runs over 3 1/3 innings.
