The Athletics are expected to promote Arnold from Double-A Midland to Triple-A Las Vegas on Tuesday, Martin Gallegos of MLB.com reports.

One of the Athletics' top pitching prospects, Arnold will get his first taste of the Pacific Coast League on the heels of a magnificent stretch at Midland. Since serving up a season-high seven runs on 12 hits and three walks in a May 27 start versus Amarillo, Arnold has delivered a 2.43 ERA, 1.18 WHIP and 73:25 K:BB across 66.2 innings in his ensuing 13 starts.

The White Sox selected Pham's contract from Triple-A Charlotte on Tuesday.

The veteran outfielder was acquired from the Phillies for cash considerations Monday and will quickly join the White Sox with MLB rosters expanding to 28 players Tuesday. Pham went 0-for-13 in nine games for the Mets early this season but has spent most of the year with the Phillies at Triple-A, where he posted a .239/.365/.410 slash line with eight homers in 44 contests.

The Orioles selected De Leon's contract from Triple-A Norfolk on Tuesday, Andy Kostka of TheBanner.com reports.

De Leon holds a 4.73 ERA, 1.48 WHIP and 121:53 K:BB over 99 innings between Double-A Chesapeake and Norfolk this season. He was recently shifted to the bullpen at Norfolk but has been shaky, allowing four runs with a 6:6 K:BB over 3.2 innings. However, De Leon has a big arm and could be a weapon in relief for the Orioles if he can find the strike zone.

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 Guardians recalled Schneemann from Triple-A Columbus on Tuesday, Tim Stebbins of MLB.com reports.

Schneemann hit .326/.457/.533 in 25 games for Columbus after being demoted in late July. He's sporting just a .597 OPS in the majors this season and should serve in a backup role at multiple positions in September.

The Orioles optioned Povich to Triple-A Norfolk on Tuesday, Jacob Calvin Meyer of The Baltimore Sun reports.

The move comes one day after Povich held the Rockies to one run over five innings in a spot start Monday at Coors Field. Povich will rejoin the Norfolk rotation but could get another look in the majors later this month, depending on where the Orioles are in the playoff hunt.

The Rays reinstated Mesa (hamstring) from the 10-day injured list Tuesday.

The 24-year-old has been sidelined since Aug. 18 due to a strained left hamstring, but he's ready to rejoin the active roster after going 4-for-18 with two homers during a five-game rehab assignment. Mesa and Jonny DeLuca could operate as a platoon in right field, with Mesa holding the advantage for playing time as a left-handed hitter.

The Blue Jays acquired Rodriguez from the Dodgers on Tuesday in exchange for Sebastian Rodriguez.

Jose Rodriguez, 25, has logged a 3.38 ERA and 36:18 K:BB across 29.1 innings this season with Triple-A Oklahoma City. The right-hander figures to report to Triple-A Buffalo for now, but the Blue Jays could give him a look at some point this month.

The Orioles recalled Kjerstad from Triple-A Norfolk on Tuesday, Andy Kostka of TheBanner.com reports.

After getting a late start to this season due to a hamstring strain, Kjerstad has slashed .289/.337/.462 with 11 home runs over 79 contests with Norfolk. The Orioles already have three left-handed or switch-hitting outfielders ahead of Kjerstad in the pecking order, so he's a long shot to receive regular playing time in September.
