The Red Sox recalled Olds from Triple-A Worcester on Tuesday, Tim Healey of The Boston Globe reports.

The right-hander was optioned to Worcester over the weekend but is already back in the big leagues since Tyron Guerrero (shoulder) landed on the injured list. Olds made six appearances for Boston after getting his first promotion to the majors in mid-August, and he pitched well with an 8:3 K:BB across six scoreless innings.

The Red Sox placed Guerrero on the 15-day injured list Tuesday with right shoulder inflammation.

Guerrero was charged with three runs while recording only one out in Monday's win over the Mariners, and a day later he's now on the IL. Interim manager Chad Tracy said he's "very hopeful" Guerrero will be back when his 15 days are up, per Tim Healey of The Boston Globe. The 35-year-old has been a pleasant surprise in the Boston bullpen this season, collecting a 3.26 ERA and 36:7 K:BB over 38.2 frames.

The Mariners signed Milner to a minor-league contract Monday and selected his contract from Triple-A Tacoma.

Milner was released by the Cubs on Sunday but has quickly landed on his feet. The southpaw reliever hasn't pitched in the majors since undergoing an appendectomy in late June, but he's healthy now and will give manager Dan Wilson another lefty reliever. Milner has logged a 3.53 ERA, 1.21 WHIP and an 18:9 K:BB over 35.2 innings in the big leagues this season.

The White Sox designated Gilbert for assignment Tuesday.

The left-hander was optioned to Charlotte on Monday and has now lost his place on Chicago's 40-man roster. Gilbert made five appearances for the White Sox this year and surrendered eight earned runs in six frames.

The White Sox recalled McDougal from Triple-A Charlotte on Tuesday.

The right-hander will rejoin the big-league roster Tuesday as rosters expand by two players for the final month of the regular season. McDougal surrendered a run on three walks over one-third of an inning during his MLB debut in mid-August. He has a 4.12 ERA, 1.38 WHIP and 43:26 K:BB over 39.1 innings for Charlotte this year.

The Guardians selected Hernandez's contract from Triple-A Columbus on Tuesday, Tim Stebbins of MLB.com reports.

Hernandez got a late start to the season after getting injured in a car accident back in January, but he's authored a 5.40 ERA and 20:7 K:BB over 13.1 innings with Columbus. The big righty will work in low-leverage spots.

The Rays recalled Cook from Triple-A Durham on Tuesday.

Cook was called up for his MLB debut in late July and was returned to Durham after giving up three runs with a 2:2 K:BB in two relief appearances. The right-hander has made 38 appearances at Triple-A this year and has a 4.53 ERA, 1.16 WHIP and 47:16 K:BB across 43.2 innings.

The Rangers signed Williams to a one-year contract Tuesday.

Williams was cut loose by the Nationals on Sunday despite posting a 2.65 ERA and 22:6 K:BB over 17 innings. He appears destined for a long-relief role with the Rangers, though the veteran righty offers the ability to make some starts down the stretch, if needed.

The Twins recalled Acton from Triple-A St. Paul on Tuesday.

Acton yielded five runs (two earned) with a 9:3 K:BB over 6.2 innings with the Twins earlier this season, and he's logged a 2.55 ERA and 23:8 K:BB in 17.2 frames with St. Paul. The 28-year-old will give the Twins a fresh arm in middle relief.

The Red Sox selected Paez's contract from Triple-A Worcester, and he'll start Tuesday's game against the Mariners.

A Rule 5 Draft pick by the White Sox over the winter, Paez was returned to the Red Sox in early April after making three appearances for Chicago. The right-hander spent most of the campaign at Double-A Portland, where he posted a 4.41 ERA, 1.02 WHIP and 56:5 K:BB across 49 innings. He made his last three appearances for Worcester and was dominant while scattering seven hits and posting an 18:2 K:BB across 12.1 frames. Paez will likely be in store for just one start while the Red Sox build in extra rest for Sonny Gray ahead of his next turn through the rotation.
