Diamondbacks selected the contracts of RHP Jonathan Loáisiga, RHP Joe Ross and INF Ildemaro Vargas.

Loáisiga looked like one of Arizona’s best relievers this spring, and he should be a part of the eighth- or ninth-inning mix right away. If he can just stay healthy, he might wind up leading the team in saves. Still, we’re talking about a 31-year-old who has only once topped 50 innings in the majors. He hasn’t made more than 30 appearances since 2022.
