Swanson was optioned to the Mariners' alternate training site Saturday.

EDGE Analysis

Swanson cruised to a 2.84 ERA and 0.63 WHIP in 6.1 spring innings, but that evidently wasn't enough to earn an Opening Day roster spot. With a career 6.58 ERA in 65.2 major-league innings, Swanson will presumably fill a low-leverage role if and when he returns to the majors.

Swanson (forearm) was reinstated from the 10-day injured list Monday.

EDGE Analysis

Swanson will wind up missing just shy of a month with a strained right forearm. He hadn't pitched well in six appearances prior to the injury, allowing nine runs in 5.1 innings of work, though that did at least come with a 7:1 K:BB. Aaron Fletcher was optioned in a corresponding move.

Swanson (forearm) continues to throw at the Mariners' alternate training site in Tacoma with an eye on returning before the end of the season, Greg Johns of MLB.com reports.

EDGE Analysis

Swanson was scheduled to throw in an intrasquad game Friday that was ultimately cancelled due to poor air quality stemming from wildfires on the West Coast. Swanson has been on the injured list since Aug. 20, and he now has just over two weeks of time remaining to get some regular-season action in.

Swanson (forearm) worked out with the team Thursday and could be activated from the injured list in the near future, Greg Johns of MLB.com reports.

EDGE Analysis

Swanson was placed on the injured list Aug. 20 with a forearm strain. No exact timetable has been established for when the right-hander could be activated, but it sounds like sometime within the next week is not out of the question. The 27-year-old has struggled in six appearances this season, allowing nine runs in just 5.1 innings.

Swanson was placed on the 10-day injured list with a right forearm strain, retroactive to Aug. 17.

EDGE Analysis

Swanson has labored through his past two appearances as he's given up six runs on four hits while hitting two batters and striking out two over one inning. His injury could help provide an explanation behind his back-to-back losing efforts. The exact severity of the issue isn't known, and it's unclear how much time he'll miss as a result of the injury.

Swanson (0-1) was tagged with the loss and a blown save Wednesday against the Rangers after giving up five runs on three hits while striking out one in two-thirds of an inning. He also hit two batters.

EDGE Analysis

Swanson was all over the place Wednesday and gave the game away in the bottom of the eighth -- the Mariners had a 4-2 lead when Swanson entered the contest and were down 6-4 when he left. He kicked things off striking out Nick Solak, but then Swanson allowed four straight batters to reach base with a single, a double, a hit by pitch and an RBI single. He was able to record the second out on a sac fly from Shin-Soo Choo that scored Elvis Andrus, and Swanson also hit Isiah Kiner-Falefa before departing the contest. This is an outing the 26-year-old right-hander will try to forget as soon as possible.

Swanson struck out two in a clean ninth inning in a loss to the Athletics on Sunday.

EDGE Analysis

Just recalled from the Mariners' alternate training site earlier in the day, Swanson was put right to work by manager Scott Servais, and the right-hander needed just nine pitches to get through the trio of Austin Allen, Tony Kemp and Marcus Semien. Swanson was deployed as both a starter and reliever during his rookie 2019 campaign, finishing with a 5.74 ERA and 1.17 WHIP over 27 appearances (eight starts). The 26-year-old will aim to do a better job of keeping the ball in the park -- something he never had trouble with during his minor-league career -- after surrendering a bloated 2.6 HR/9 across his 58 innings last season.

The Mariners recalled Swanson from their alternate training site prior to Sunday's game against the Athletics.

EDGE Analysis

Swanson missed out on a spot on the Mariners' season-opening 30-man roster, but he'll now move up to the big club to reinforce the bullpen in the short term. Third catcher Joe Odom was optioned to the Mariners' alternate camp in a corresponding move.

Swanson, who entered spring camp with a back issue, is now fully healthy according to pitching coach Pete Woodworth, Greg Johns of MLB.com reports.

EDGE Analysis

Swanson was able to log three Cactus League appearances as he worked through the final stages of his back strain before spring training was suspended, generating a 3.00 ERA across three innings. The 26-year-old right-hander is looking to bounce back from a 2019 rookie campaign during which he put up a 1-5 record and 5.74 ERA across 27 appearances (eight starts). Swanson is expected to work exclusively out of the bullpen whenever the regular season begins, with the possible exception being if multiple injuries were to strike the starting rotation.

Swanson, who was previously struggling with a back injury, emerged from his Cactus League debut Monday without any issues, Greg Johns of MLB.com reports.

EDGE Analysis

The right-hander allowed an earned run on two hits during his one inning against the Rockies, but he also recorded a pair of strikeouts. The fact Swanson didn't suffer any setbacks is certainly encouraging, as is manager Scott Servais' observation that the reliever improved the more his outing progressed Monday.
