Rasmussen will serve as the Rays' opener for Saturday's game versus the Guardians, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

Rasmussen has put up a 2.79 ERA and 1.09 WHIP across 19.1 innings this season, and he'll now be entrusted with at least the first three batters of Saturday's contest, though most of his appearances this season have lasted two full innings. Tyler Alexander is expected to handle bulk-relief duties once Rasmussen exits.
