Speier was awarded a spot on the Opening Day roster, Anne Rogers of MLB.com reports.
Speier finished 2021 well with a 1.17 ERA and 1.30 WHIP across 7.2 innings after spending the bulk of the season with Triple-A Omaha. The southpaw saw mainly low-leverage work, and with plenty of bullpen arms ahead of him, Speier should expect to see most of his time in the middle innings in 2022.
