Nelson is slated to start Monday's game against the Pirates at Chase Field.
Eduardo Rodriguez (shoulder) has resumed throwing but isn't eligible to return from the 15-day injured list until next weekend, so Nelson will make a second straight turn through the Arizona rotation in his place. In his most recent start this past Tuesday, Nelson took a no-decision despite limiting a tough Dodgers lineup to one run on three hits and one walk. A home matchup with the 19-35 Pirates represents a more favorable spot for Nelson to claim his second win of the season.
