Rockies Minor League outfielder Tyler Massey hit an opposite-way home run to right field in the sixth.
The teams each played their hands closely. Lohse will not start during the three-game series with the Rockies to start the season. Meanwhile, the Rockies put lefty Jorge De La Rosa -- who is expected to start Tuesday in the second game of the year -- in a Minor League game against the D-backs.
De La Rosa, who missed his last start with left forearm tightness, went six innings and gave up one earned run on three hits, which included a home run, with four strikeouts and two walks. The D-backs squad included Major Leaguers Jason Kubel and Miguel Montero.
Up next: Done with Cactus League play, the Rockies will be off Friday but will meet the Mariners in an exhibition game in Salt Lake City on Saturday at 1:05 p.m. MT. Lefty Jeff Francis, who will start next Friday's home opener, will start for the Rockies. On Friday, righty Juan Nicasio will do his work in a Minor League game.
