Diamondbacks pitcher Dontrelle Willis was victorious in his first start for the team on Saturday.

Willis pitched six scoreless innings and scored a run as Arizona held on for a 4-3 win over Colorado.

The Diamondbacks acquired Willis from the Tigers on Tuesday and he gave up five hits, walked four and hit a batter, but the Rockies were 0-for-10 with runners in scoring position.
