Dubin (forearm) made his first rehab appearance Tuesday at Triple-A Sugar Land, striking out a batter while allowing an earned run on one hit over two-thirds of an inning.

Tuesday's appearance was Dubin's first at any level since June 20, as he's been on the shelf for more than a month while recovering from a right forearm strain. He'll likely remain with Sugar Land at least through the weekend to continue his rehab assignment before Houston potentially adds him back to the big-league bullpen in the first week of August.

Criswell will start Friday's game against the Astros, Chris Cotillo of MassLive.com reports.

The right-hander was called up from Triple-A Worcester on Tuesday and will step into Boston's rotation to fill the spot vacated by Richard Fitts' demotion earlier this week. Criswell, who's worked out of the bullpen in each of his six MLB appearances this year, has a 5.06 ERA, 1.78 WHIP and 5:3 K:BB over 10.2 innings. The 29-year-old righty may be in line for just a spot start, as the newly acquired Dustin May is scheduled to start Sunday's series finale and could stick as the fifth member of the rotation over Criswell moving forward.

Kinley gave up two hits and a walk in a scoreless seventh inning during Thursday's extra-inning win over the Reds. He struck out one.

Making his debut for Atlanta after being acquired from Colorado on Wednesday, Kinley was brought in with the game tied 3-3 and nearly made a mess of things, loading the bases with one out before getting Spencer Steer to pop out and fanning Jake Fraley. With closer Raisel Iglesias surprisingly still on the roster after the trade deadline, Kinley will be on the fringes of high-leverage work for his new club while Pierce Johnson and Dylan Lee continue to handle setup duties.

Johnson (2-3) picked up the win in Thursday's 12-11 extra-inning victory over the Reds, striking out one in 1.1 perfect relief innings.

The right-hander was viewed as a potential closer candidate for the final two months of the season if Raisel Iglesias got dealt, but with Iglesias still in Atlanta after the trade deadline, Johnson will remain in a setup role. He put an impressive July in the books during which he posted a 0.75 ERA, 0.50 WHIP and 10:2 K:BB over 12 innings while notching one win and three holds in 12 appearances.

Ferguson threw a clean seventh inning with no strikeouts in Thursday's 6-0 win over the Rangers.

Ferguson got off on the right foot in his team debut, though it's worth noting he entered in a low-leverage situation as the Mariners nursed a 6-0 lead. While the 29-year-old southpaw may not be part of the high-leverage mix right off the bat, it's not out of the question that he'll eventually work his way into a setup role behind closer Andres Munoz. Ferguson is just one of two active lefties in Seattle's bullpen along with Gabe Speier.

Thornton was on crutches following Thursday's game against the Rangers and believes he suffered a serious Achilles injury, Daniel Kramer of MLB.com reports.

Thornton was injured while trying to cover first base late in Thursday's game and appeared to suffer a serious leg injury. He'll be sent for an MRI on Friday, at which time a diagnosis should become official.

Thornton suffered a left leg injury Thursday against the Rangers and departed on a cart, Adam Jude of The Seattle Times reports.

Thornton entered the game in the eighth inning and successfully recorded five outs. He then suffered what appeared to be a serious leg injury while trying to cover first base. Thornton will almost certainly need a stint on the injured list, but just how long he'll be sidelined remains to be seen.

Iglesias earned the save in Thursday's 12-11 win over the Reds in 10 innings. He struck out one in a scoreless inning.

Iglesias was seen as a likely trade candidate, though he ultimately remained with Atlanta following Thursday's deadline. Brought in to protect a one-run lead in the 10th inning, Iglesias set the Reds down in order, locking down his 13th save in 18 chances this season. After a shaky start to the year, Iglesias has now held opponents scoreless in 19 of his last 21 appearances. His ERA sits at 4.74 with a 1.15 WHIP and 48:10 K:BB across 43.2 innings.

Hiraldo was recalled by the Orioles on Thursday.

Hiraldo has spent most of the season in the minors but has made three appearances in the majors. The Orioles are dealing with injuries and also traded away depth in their bullpen, so Hiraldo could get an extended look in the majors down the stretch.

De Los Santos was optioned to Triple-A Scranton/Wilkes-Barre on Thursday, Max Goodman of NJ.com reports.

De Los Santos was activated from the injured list Saturday and has made two scoreless appearances since. The Yankees made a flurry of additions to their bullpen at the trade deadline, costing De Los Santos his spot on the big-league roster.
