Swanson (0-2) lost Tuesday's 5-4 affair with the Rangers, allowing two runs (one earned) on two hits with a strikeout in one inning.

EDGE Analysis

Swanson entered a tie game in the 10th and recorded two outs before surrendering two singles to suffer the defeat. The 27-year-old righty is in the midst of a breakout season, though he has two losses and two blown saves in his last four appearances, causing his ERA to spike from 0.47 to 2.01.

Swanson (0-1) was charged with the loss in a defeat at the hands of the Rangers on Sunday, allowing three earned runs on three hits without recording an out in the ninth inning.

EDGE Analysis

Asked to preserve a 3-1 lead when presented with only his second save opportunity of the season, Swanson immediately encountered trouble by allowing Nathaniel Lowe to reach on a single and then surrendered back-to-back home runs Andy Ibanez and Jonah Heim, the latter a game-winning blast. The stumble was highly uncharacteristic of Swanson, who'd last allowed a run May 8, a span of 12.2 innings across 12 appearances.

Swanson fired two scoreless innings in a win over the Astros on Monday, allowing no hits and one walk.

EDGE Analysis

Swanson's pair of strong frames ended up being integral to the comeback win, as he bought the Mariners some time after the Astros had racked up eight runs through the first five innings. The 27-year-old has been dominant when called upon this season, with Tuesday's effort whittling his ERA and WHIP down to tiny 0.49 and 0.82 figures, respectively, across 14 appearances.

Swanson fired a scoreless two-thirds of an inning during which he allowed a hit in a loss to the Angels on Sunday, his first appearance since being activated from the injured list Wednesday.

EDGE Analysis

The right-hander was sidelined for what amounted to nearly a month and a half with a groin injury, but he was able to pick up right where he left off in his return Sunday. Swanson now has seven consecutive scoreless efforts dating back to May 13, lowering his ERA and WHIP to an elite 0.66 and 0.80, respectively.

The Mariners activated Swanson (groin) from the 10-day injured list Wednesday, Ryan Divish of The Seattle Times reports.

EDGE Analysis

The righty made two rehab appearances with Triple-A Tacoma, allowing a solo homer and striking out one in two innings of work. Before a right groin strain sent Swanson to the IL on May 29, he posted a 0.69 ERA with 14 strikeouts and six walks in 13 innings. He made nine appearances, two of which were starts.

Swanson (groin) fired a scoreless sixth inning in Triple-A Tacoma's loss to Reno on Saturday, allowing one hit.

EDGE Analysis

Swanson was originally scheduled to kick off his rehab assignment with the Rainiers last Monday, but some back soreness following a tune-up bullpen session during the preceding weekend put a hold on those plans. However, the right-handed reliever encouragingly was able to tolerate a solid 20-pitch workload over his one frame Saturday, and he'll likely make at least one more rehab appearance before activation is considered.

Swanson (groin) did not make a scheduled rehab appearance with Triple-A Tacoma on Monday due to back soreness, the Associated Press reports.

EDGE Analysis

The right-hander was slated to officially begin his rehab assignment Monday after throwing a bullpen session over the weekend, but back soreness apparently stemming from that activity put a damper on that plan. Assuming the issue doesn't develop into anything more debilitating, Swanson will likely be cleared to make his debut with the Rainiers at some point in the coming days.

Swanson (groin) has joined Triple-A Tacoma on its current road trip and will throw a bullpen session before officially jumping into a rehab assignment, the team's official site reports.

EDGE Analysis

The right-hander got through a bullpen session earlier this week without any apparent setbacks, and he's now on the verge of his first taste of game action since May 28. Upon rejoining the big-league club Swanson may be inserted into some high-leverage scenarios fairly quickly, as he boasted an 0.69 ERA and 0.77 WHIP across 13.0 innings prior to the injury.

Swanson (groin) will throw a bullpen session Monday and is likely headed to a rehab assignment with Triple-A Tacoma shortly thereafter, the Associated Press reports.

EDGE Analysis

The 27-year-old was projected for an extended absence when first placed on the injured list May 29, and although he's still expected to be on the shelf into July, he appears to be making steady progress. If all goes well with Sunday's session, Swanson could potentially embark on his rehab assignment before the coming week is out.

Manager Scott Servais said Swanson (groin) is expected to be sidelined for an extended period, Ryan Divish of The Seattle Times reports.

EDGE Analysis

The 27-year-old doesn't have an official timeline for his return after landing on the injured list with a strained right groin Saturday, but he can be ruled out indefinitely for now. Swanson was pitching well prior to the injury with a 0.69 ERA, 0.77 WHIP and 14:6 K:BB across 13 innings.
