Faedo allowed three runs on three hits and a walk across 1.2 innings of relief in Thursday's 9-1 loss to the Blue Jays. He struck out one.

After starting the season with a 2.25 ERA across his first 14 appearances, Faedo has allowed runs in his last three outings, and he has a 9.00 ERA during that stretch. The righty was a middling starter the last two years, and while he's looked a little better out of the bullpen, he may be regressing closer to his career 4.67 ERA. Faedo doesn't have a ton of fantasy value in his current middle-relief role, particularly given his recent struggles.

Holmes earned the save in Thursday's 5-0 win over Seattle, allowing two hits while striking out two in 1.1 innings.

He came on in relief in the eighth after Nick Burdi loaded the bases. Holmes induced a grounder off the bat of Luke Raley for the final out before working around a pair of singles in the ninth to earn his 14th save. It's a nice bounce-back effort from Holmes, after he allowed four runs in a blown save against Seattle on Monday, the first four runs he's allowed this season. Overall, the 31-year-old right-hander sports a 1.64 ERA with a 1.23 WHIP and 25:6 K:BB across 22 innings this year.

The Mariners claimed Salazar off waivers from the Dodgers on Thursday, Fabian Ardaya of The Athletic reports.

After pitching two scoreless innings for the Dodgers on May 15, Salazar was optioned to Triple-A and later designated for assignment. He'll once again hold a 40-man roster spot with his new club, though he will begin his tenure with the Mariners at Triple-A Tacoma. The 26-year-old right-hander has logged a 5.61 ERA and 1.78 WHIP through 33.2 innings across seven starts in the minors.

Armstrong will serve as the Rays' opening pitcher for Friday's game against the Royals, Marc Topkin of the Tampa Bay Times reports.

The right-hander will likely cover no more than an inning or two before turning the ball over to lefty Tyler Alexander, who is slated to handle the bulk of the innings out of the bullpen. Armstrong will be serving as an opener for the fourth time this season after allowing four runs (three earned) with an 8:2 K:BB over four innings in his first three starts.

The Tigers optioned Lange to Triple-A Toledo on Thursday.

A day after allowing four earned runs in one inning during Wednesday's loss to the Royals, Lange will be sent to Triple-A in order to get back on track. The 28-year-old owns a 4.34 ERA and 1.77 WHIP alongside a 21:17 K:BB through 18.2 innings this season, and he figures to return to Detroit's bullpen once he starts turning in promising results with Toledo. In the meantime, Mason Englert will come up from Triple-A to take Lange's place.

The Tigers recalled Englert from Triple-A Toledo on Thursday, Cody Stavenhagen of The Athletic reports.

Englert has put up a 2.35 ERA and 34:9 K:BB over 23 innings with Toledo this season. The 24-year-old collected a 5.46 ERA across 31 appearances for the Tigers last year. He should operate in low-leverage situations.

Muller (0-1) took the loss in an extra-innings defeat at the hands of the Rockies on Wednesday, allowing two runs (one earned) on two hits over one inning.

Muller was entrusted with preserving a 2-2 tie when he entered in the 12th inning, but he faltered almost immediately by giving up a go-ahead two-run home run to Ryan McMahon with designated runner Jake Cave aboard. Oakland would halve its two-run deficit in the home half of the frame but fall short of knotting the score back up, saddling Muller with his first loss. The southpaw sports a respectable 3.94 ERA and 1.18 WHIP, but he's allowed at least one run in nine of his 12 appearances.

The Orioles recalled Heasley from Triple-A Norfolk on Thursday, Dan Connolly of The Athletic reports.

Heasley has been torched for seven runs (six earned) over 4.1 innings during his time with the Orioles this season. He's been much better at Norfolk, though, yielding just one run with an 18:4 K:BB in 20 frames. The right-hander should operate in middle relief.

The Mariners optioned Bolton to Triple-A Tacoma on Thursday.

Bolton will cede his spot on the 26-man roster and in the bullpen to right-hander Mike Baumann, whom the Mariners acquired from the Orioles on Wednesday. In 15 relief appearances for Seattle this season, Bolton has compiled a 4.41 ERA and 1.29 WHIP across 16.1 innings in relief.

Poche (back) threw a 15-pitch bullpen session Wednesday, MLB.com reports.

Poche had made little progress since suffering a back injury in late April, but he felt good after his throwing session Wednesday. He'll continue to ramp up in the hopes of facing hitters by May 30 as the next step in his recovery.
