Diamondbacks Select Scott McGough, Option Yilber Diaz

The Arizona Diamondbacks made several bullpen-related roster moves ahead of Sunday's game against the Atlanta Braves, selecting Scott McGough's contract from Triple-A Reno. In corresponding moves, top pitching prospect Yilber Diaz was optioned back to Reno and reliever J.P. Feyereisen was designated for assignment to clear a 40-man roster spot for McGough. McGough, who previously pitched for Arizona and signed a minor league deal in February after free agency, had a 5.23 ERA with strong strikeout-to-walk numbers in Reno despite not allowing any home runs. Diaz was called up recently to provide bullpen coverage but is now poised to resume starting in the minors, while Feyereisen, who struggled in his most recent appearance, loses his roster spot after limited action this season. These changes come as Arizona seeks to stabilize its bullpen following a blown lead and extra-inning loss on Saturday. The moves reflect the team's immediate need for fresh arms and roster flexibility.
