Diamondbacks' Kyle Nelson: Will serve as opener Saturday

Nelson will serve as the Diamondbacks' opener Saturday versus the Pirates, Theo Mackie of The Arizona Republic reports.

It'll be his first appearance in that role this year. Nelson has registered a strong 2.76 ERA with 42 strikeouts over 32.2 innings of relief this season with Arizona, but he'll probably only be asked to handle a frame or two Saturday against Pittsburgh and offers little fantasy appeal.
