DENVER (AP) — Colorado right-hander German Marquez homered against Arizona infielder Daniel Descalso, helping the Rockies pound the Diamondbacks 19-2 on Wednesday night.
Marquez (8-8) pitched six innings of two-run ball. He connected for his first career homer in the fifth.
Marquez's drive to center was the first homer by a pitcher off a position player since Mike LaCoss went deep for the Giants against San Diego's Dane Iorg on June 23, 1986, according to STATS.
Carlos Gonzalez homered twice for the Rockies and drove in six runs. Charlie Blackmon and Ian Desmond also went deep.
