Mederos (0-2) allowed six runs on four hits and two walks while striking out four over four innings to take the loss versus the Cubs on Saturday.

While Mederos didn't give up an excessive number of baserunners, he paid severely for his few mistakes. Kyle Tucker took him deep for a two-run home run in the third inning, and Reese McGuire added a grand slam in the fourth. Mederos has now given up four homers over 13 innings across his last three starts. He's posted a 7.41 ERA, 1.76 WHIP and 14:12 K:BB through 17 innings in the majors this season.

Abreu earned the save in Saturday's 9-8 win over the Orioles, striking out one in a perfect ninth inning.

Abreu was called on to protect a one-run lead in the ninth and needed just nine pitches to notch his second save in as many days. The 28-year-old has now thrown 10 consecutive scoreless outings to start August, posting a 13:3 K:BB during that stretch. For the season, he owns a 1.52 ERA, 0.99 WHIP and 89:25 K:BB across 59.1 innings while converting all three of his save chances since Josh Hader (shoulder) went on the injured list.

Hoffman was charged with his sixth blown save of the season Saturday, giving up one run on one hit and one walk in the ninth as the Blue Jays downed the Marlins 7-6 in 12 innings. He struck out one.

Called upon to protect a 4-3 lead, Hoffman issued a leadoff walk to Eric Wagaman, setting Javier Sanoja up to tie the game with a one-out single. It's the first run Hoffman has allowed in August, but he's blown two of five save chances on the month despite a 1.04 ERA in 8.2 innings thanks to a 12:7 K:BB. He remains two saves shy of his first career 30-save campaign.

Vest retired all four batters he faced to earn the save in Saturday's 4-2 win over the Royals. He recorded two strikeouts.

Vest was summoned with a runner on third in the eighth inning and struck out Maikel Garcia before working a clean ninth. The 30-year-old has held opponents scoreless in eight of 10 August outings and now sports a 2.67 ERA, 1.05 WHIP and 64:16 K:BB across 57.1 frames while converting 19 of 24 save chances. He continues to split closing duties with Kyle Finnegan, who was likely unavailable after throwing two innings Friday.

Martin (calf) left Saturday's live batting practice session early and will not be reinstated from the injured list anytime soon, Jeff Wilson of AllDLLS.com reports.

Martin seemingly sustained a setback Saturday in his recovery from a left calf strain. The reliever has been on the shelf since July 26 and was initially given a 4-to-6-week timeline for return. However, the 39-year-old will likely need more than six weeks and shouldn't be expected back until mid-September, at the earliest.

The Royals recalled Bowlan from Triple-A Omaha on Saturday.

Bowlan rejoins the big-league bullpen after three weeks at Omaha, filling the spot vacated by Bailey Falter (bicep), who was placed on the 15-day injured list. Bowlan has a 4.73 ERA and a 24:11 K:BB across 26.2 innings for the Royals this season.

Poteet (shoulder) is beginning a minor-league rehab assignment with Triple-A Norfolk on Saturday, Roch Kubatko of MASNSports.com reports.

Poteet has been on the shelf since late April due to right shoulder inflammation. He has made only one regular-season appearance this year, allowing five runs over 2.2 innings against Cincinnati on April 20. Poteet will presumably need to make several rehab outings given the length of his absence. He could be activated by the Orioles sometime in September if he doesn't experience any setbacks.

Sousa has been diagnosed with a "low-grade elbow flexor/pronator strain" and will not throw for at least two weeks, Matt Kawahara of the Houston Chronicle reports.

Sousa landed on the injured list Friday and underwent an MRI, the results of which revealed the flexor/pronator strain. The southpaw will be evaluated in early September, and he's expected to be sidelined from any throwing for a minimum of two weeks. This is a big blow to Houston's bullpen, as Sousa has excelled with a 2.84 ERA, 1.03 WHIP and 59:15 K:BB over 50.2 innings while notching four saves and eight holds across 44 appearances.

The Astros designated Dubin for assignment Saturday, Matt Kawahara of the Houston Chronicle reports.

Dubin has had an injury-plagued campaign, as he's dealt with separate shoulder, ankle and forearm issues at points this season. The right-hander has struggled during his time with Houston, posting a 5.61 ERA, 1.48 WHIP and 21:8 K:BB over 25.2 innings. AJ Blubaugh was called up from Triple-A Sugar Land in a corresponding move, but perhaps the more important aspect of Dubin being DFA'd is that it opens up a spot on the Astros' 40-man roster. That spot will likely go to Yordan Alvarez (hand), who is close to being activated from the 60-day IL.

Finnegan (3-4) tossed two scoreless innings of relief to earn the win in Friday's 7-5 victory over the Royals. He walked one and struck out one.

Finnegan worked the seventh and eighth innings to earn the win out of the bullpen, with Will Vest covering the ninth. The former has two wins since joining Detroit at the trade deadline to go along with four saves and a hold. He's also sporting an impressive 0.00 ERA and 0.38 WHIP with 12 strikeouts across 10.2 innings with his new team. Both Finnegan and Vest are seeing ninth-inning work for the Tigers, giving both pitchers fantasy appeal but also capping their respective ceilings.
