The Rays optioned Waguespack to Triple-A Durham on Saturday.
Waguespack will be squeezed off the active roster as Tyler Alexander returns from the bereavement list Saturday. The 30-year-old right-hander posted a 5.40 ERA and 2.30 WHIP across 10 innings through four appearances and may return to Tampa Bay later this season should the Rays' pitching depth be tested again.
