Swanson served as the opener in Wednesday's loss to the Athletics and allowed two earned runs on two hits and a walk across two innings. He also recorded two strikeouts and did not factor into the decision.

EDGE Analysis

Just recalled from Triple-A Tacoma on Tuesday, Swanson was able to consume a couple of frames for manager Scott Servais, but he wasn't particularly effective. The right-hander labored through 48 pitches during that modest span, particularly running into trouble in the second when he allowed a two-run home run to Jurickson Profar. Swanson has struggled at both the Triple-A and big-league levels this season, and it remains to be seen how long his current stint with the Mariners will last.

Swanson will work as the opener Wednesday against the A's.

EDGE Analysis

Tommy Milone will pitch the bulk of the innings for Seattle in this contest, per Greg Johns of MLB.com. After failing as a big-league starter earlier in the season, Swanson has pitched three or fewer innings in each of his last nine appearances at Triple-A, but he has not had much success in that role either (6.98 ERA, 1.76 WHIP, 20 strikeouts in 19.1 innings).

Swanson was recalled by the Mariners on Tuesday, Greg Johns of MLB.com reports.

EDGE Analysis

In seven appearances (six starts) with the major-league club through early May, Swanson recorded an ERA of 8.04, but he had decent command with a 24:5 K:BB. Since then, he's only managed an ERA of 6.98 and a 20:12 K:BB with Triple-A Tacoma. While the right-hander was mostly used as a starter during his previous stint in Seattle, it seems likely that he will pitch primarily in relief for the time being. Outfielder Mac Williamson was designated for assignment in a corresponding move.

Swanson was optioned to Triple-A Tacoma on Friday.

EDGE Analysis

Swanson was knocked around in his last start against the Twins, allowing eight runs and striking out three over just three frames, so his time in the big leagues has come to an end for now. Matt Festa was recalled from Triple-A in a corresponding move.

Swanson (1-5) gave up eight earned runs on nine hits over just three innings in a loss to the Twins on Thursday. He struck out three with no walks.

EDGE Analysis

The right-hander was absolutely lit up for the third time in four starts, as the Twins touched him up for four long balls before chasing him from the contest after just three frames and 64 pitches. It's been tough sledding so far for Swanson, who sees his ERA rise to 8.04 and his WHIP to 1.44 through six starts.

Swanson (1-4) took the loss after giving up seven runs on seven hits while striking out four over 4.2 innings Friday night against the Red Sox.

EDGE Analysis

Swanson had a rough go of it, allowing four runs in the third inning, another in the fourth and two more in the fifth prior to his removal from the contest. His inability to keep the ball in the yard was a key issue for Swanson, as four of his seven runs came via the long ball. Following Friday's outing, he owns a 6.35 ERA with a 21:5 K:BB across 28.1 frames in 2019.

Swanson (1-3) tossed six shutout innings Sunday, allowing only one hit with three strikeouts and three walks while earning the win against the Indians.

EDGE Analysis

The right-hander's first victory of 2019 was memorable, as he posted a season high in walks but also a season low in hits allowed. With this win, Swanson snapped a three-game losing streak, in which he gave up five home runs in 15.2 innings. Overall, he is 1-3 with a 4.94 ERA, 1.23 WHIP and 17 strikeouts in 23.2 innings this year. His next start is scheduled for Friday at the Red Sox.

Swanson (0-3) yielded nine runs (six earned) on 11 hits across four innings while taking the loss to Texas on Sunday. He struck out two batters and gave up two homers.

EDGE Analysis

The 6-foot-3 rookie turned in his second consecutive ugly outing. He never really settled in Sunday, allowing a pair of two-run shots to Hunter Pence and Elvis Andrus in the third inning and later allowed three runs in the fifth without recording an out. He now owns a 6.62 ERA in 17.2 innings, but his 14:2 K:BB is promising. If he sticks around with Seattle, his next start should be next Sunday against Cleveland.

Swanson (0-2) took the loss Tuesday, giving up five runs (four earned) on seven hits over 5.2 innings while striking out three as the Mariners fell 6-3 in San Diego.

EDGE Analysis

Franmil Reyes was the his nemesis in this one, taking Swanson deep in the second and sixth innings. The right-hander has served up three homers in 11.2 frames over his first two MLB starts, leading to a 4.61 ERA, but his 8:0 K:BB is encouraging. Swanson will next take the mound Sunday, at home against the Rangers.

Swanson (0-1) took the loss Wednesday as the Mariners fell 1-0 to Cleveland, giving up one run on two hits over six innings while striking out five.

EDGE Analysis

The right-hander made only one real mistake in first big-league start, but Jake Bauers put it over the fence for the game's only run. Afternoon shadows likely helped Swanson a great deal -- the two teams combined for only six hits -- but he still looked good and didn't display any nerves. Seattle hasn't yet confirmed he'll remain in the rotation, but assuming Swanson passed his audition and will continue filling in for Wade LeBlanc (oblique), his next turn would come in San Diego on Tuesday.
