Clayton Mortensen is still a member of the Red Sox organization.
Mortensen, who was designated for assignment Saturday, has cleared waivers. The right-hander has been outrighted to Triple-A Pawtucket, according to multiple reports.
The Red Sox knew when they designated Mortensen for assignment that there was a chance they could lose the reliever. However, no teams put in a claim, and he will remain the Red Sox’ property, which could become important at some point this season.
Mortensen has had a rocky campaign, going 1-2 with a 5.34 ERA in 30 1/3 innings over 24 appearances. The 28-year-old former first-round pick pitched well for Boston last season, though, going 1-1 with a 3.21 ERA in 42 innings over 26 appearances.
Mortensen, who was out of options, was designated for assignment Saturday so that the Red Sox could make room for infielder Jonathan Diaz. The Sox wanted to add an infielder in the wake of Stephen Drew suffering a hamstring injury.
