Right-handed pitcher David Colvin of the High Desert Mavericks has been place on the disabled list by the parent Seattle Mariners.

Colvin, 24, had appeared in 31 games, 30 of those out of the bullpen. He had a 5-0 record and 2.38 ERA in 56 2/3 innings. Those are pretty impressive numbers given the hitter-friendly California League venue in which he pitches.

Colvin has not pitched since July 27 but was only recently placed on the disabled list.

Colvin was a 27th round draft pick by the Mariners in 2011.

His loss is big for the Mavericks who are trying to hold off Rancho Cucamonga and Lake Elsinore for the final South Division playoff spot with the season over in less than two weeks.
