Venditte was designated for assignment by the Mariners on Wednesday.
The switch-pitcher was the odd man out following the team's trade that added three players Wednesday evening. Venditte has plenty of team control remaining, but serves generally as a middle reliever and is unlikely to find a high-leverage situation elsewhere. Still, it's possible another team will take a shot at him in the waivers. If not, it's possible he will be attend Mariners spring training as a non-roster invitee.
