Before last night’s game against the Rangers, the Mariners announced they were placing right-hander Erik Swanson on the 10-day injured list due to a right groin strain. Reliever Will Vest was reinstated from the COVID-19 injured list to replace Swanson on the active roster. To create 40-man roster space for Vest’s return, righty Casey Sadler was transferred from the 10-day IL to the 60-day IL.
Swanson, who was acquired from the Yankees as part of the 2018 James Paxton deal, has gotten off to a nice start for Seattle this year. He’s pitched in nine games (including two brief starts) and combined for thirteen innings of one-run ball, striking out fourteen while issuing six walks. He won’t continue to strand every baserunner that reaches against him (the only run allowed came on a Joey Gallo homer) or benefit from a .115 opponents’ batting average on balls in play. However, Swanson has generated swings and misses on a strong 13% of his offerings and was once a decently-regarded prospect, so he looks like a solid middle innings option once he returns to health.
Vest went on the COVID IL alongside a few other Seattle relievers on May 21. He’s pitched 21 1/3 innings of 4.22 ERA/4.93 SIERA ball this season. As a Rule 5 draftee, Vest must remain on the Mariners active roster all year if Seattle wishes to keep his contractual rights long-term.
Sadler went on the IL on May 1 with an impingement in his throwing shoulder. Yesterday’s transfer means he can’t return for at least 60 days from the date of his initial IL placement, so he’ll be out through the end of June at a minimum.
