What happened: The Diamondbacks designated Paul Sewald for assignment earlier this week. A corresponding roster move placed a recalled right-hander on the 60-day injured list.
Why it matters: The claim keeps Sewald in the majors without Arizona receiving a trade return. His new club adds an experienced relief option for the final weeks of the regular season.
By the numbers: Sewald recorded his 21st save with a perfect ninth on July 10, just over a month before Arizona removed him from its bullpen.
What to watch: His first bullpen assignment will clarify how quickly he enters the relief mix.
