The White Sox Sox" data-type="SPORTS_OBJECT_TEAM" data-league-abbreviation="MLB" data-team-abbreviation="CHW">White Sox optioned White to Triple-A Charlotte on Tuesday.

He's clearing out to make room for Bryan Hudson, who will join the active roster after being claimed off waivers Sunday. White had been recalled over the weekend but did not make an appearance.

Minnesota designated McCaughan for assignment Tuesday.

The right-hander joined the big club Monday but will lose his place on the 26-man and 40-man rosters just a day later. McCaughan made three appearances for the Twins early in the season and allowed one earned run with a 6:1 K:BB over 5.1 innings, but he's struggled to a 5.35 ERA in 17 outings (10 starts) with Triple-A St. Paul.

The Twins claimed Kriske off waivers Tuesday.

The right-hander was designated for assignment by the Cubs over the weekend, and the Twins claimed him in order to round out their bullpen coming out of the trade deadline. Kriske delivered six scoreless frames with a 4:5 K:BB with Chicago and has a 3.13 ERA at the Triple-A level this season.

Slaten (shoulder) threw off a mound at Fenway Park on Tuesday, Rob Bradford of WEEI.com reports.

Slaten looked to be throwing at full effort in his first time tossing from the bump since he landed on the injured list in early June due to right shoulder inflammation. The right-hander will surely require some rehab appearances before being activated from the 60-day injured list, and it's not clear when he might be ready for game action in the minors.

Okert will serve as the Astros' opening pitcher in Tuesday's game versus the Marlins, Matt Kawahara of the Houston Chronicle reports.

Okert will cover the first inning or two before handing things off to AJ Blubaugh, who is expected to be the bulk reliever. The left-handed Okert has had a dynamite season out of the Astros' bullpen, registering a 2.90 ERA and 59:11 K:BB over 49.2 frames.

The Red Sox recalled Campbell from Triple-A Worcester on Tuesday.

Campbell has allowed two runs over two innings during his brief time in the majors this season, and he has collected a 4.17 ERA and 41:15 K:BB across 45.1 frames with Worcester. The righty will likely be used as a low-leverage reliever.

The Red Sox designated Alcala for assignment Tuesday.

Alcala has fanned 46 batters over 40.2 innings this season between the Twins and Red Sox, but he's also walked 23 while posting a 6.64 ERA. Not having minor-league options remaining will hurt him, but it would not be a surprise if another team takes a shot on the hard-throwing reliever.

Martin gave up six runs while failing to record an out in Monday's loss to the Phillies.

Martin notched a save last week against the Blue Jays, thrusting himself into the closer conversation as part of a bullpen that's lost Felix Bautista (shoulder) to injury and Gregory Soto, Seranthony Dominguez and Andrew Kittredge to trades. However, in his two appearances since that save, Martin has entered in the sixth inning both times. He managed to pitch around a couple hits in the first of those outings, but he was not so lucky Monday. The Orioles' bullpen remains unsettled, but it seems unlikely Martin will be entrusted with another save chance anytime soon.

The Orioles claimed Garcia off waivers from the Mets on Tuesday, Ari Alexander of KPRC 2 Houston reports.

Just within the last month, Garcia has bounced around from the Mets to the Yankees, back to the Mets and now to the Orioles via waivers. The righty reliever holds a 3.52 ERA and 18:4 K:BB over 15.1 major-league innings this season and will join an unsettled Baltimore bullpen.

Bednar earned a hold against Texas on Monday, striking out one batter in a perfect inning.

Bednar got the call in the eighth frame with the Yankees up by a run. He set the side down in order on 11 pitches (eight strikes). This was a much better outcome than in Bednar's team debut Aug. 1, when he allowed two runs on four hits over 1.2 innings. The veteran reliever entered in the seventh frame in that game, so it appears New York has him tabbed for a setup role. That said, Devin Williams blew his second straight save Monday and has yielded at least one run in three straight outings, so the team could shift to Bednar at closer if Williams continues to struggle.
