Megill (elbow), who was placed on the 15-day injured list earlier Wednesday, said that he's been diagnosed with a Grade 1 flexor tendon strain following an MRI and is hoping to be activated around when he's first eligible Sept. 9, Sophia Minnaert of FanDuel Sports Network Wisconsin reports. "My intentions are to be off on 15 [days], and I'm gonna do everything in my power to make that happen," Megill said.

Megill noted that his elbow felt off following his most recent appearance against the Giants on Sunday, when he needed 34 pitches to record three outs en route to suffering his third blown save in as many chances. Though elbow-related injuries are especially concerning for pitchers like Megill who are reliant on high velocity, the 31-year-old was encouraged by the results of his imaging and said that the flexor tendon strain isn't as serious as ones that he's dealt with in the past. He's hopeful that after a few days of rest, he'll be able to resume throwing again, at which point the Brewers should have a better idea whether a return in the minimum 15 days is realistic. Abner Uribe converted the Brewers' last save chance in Monday's win over the Diamondbacks and is likely to take over as Milwaukee's closer while Megill is shelved.

Brazoban is slated to undergo an MRI on his oblique area Wednesday and could land on the 15-day injured list, Joel Sherman of the New York Post reports.

Brazoban apparently suffered the injury during his relief appearance in Tuesday's win over the Phillies. The Mets have already recalled Kevin Herget from Triple-A Syracuse to provide the team with a fresh arm in the bullpen for Wednesday's series finale and did not announce a corresponding move. Brazoban appears likely to lose his spot on the active roster prior to the game, whether it's due to a stint on the injured list or a demotion.

The Brewers placed Megill on the 15-day injured list Wednesday due to a right elbow flexor strain.

Though Milwaukee hadn't indicated that Megill was nursing an injury, he hadn't been especially sharp in his recent outings. Over his last four appearances spanning four innings, Megill backdoored his way into two wins but blew three of four save chances while allowing four runs (three earned) on seven hits and two walks across four innings. Abner Uribe has turned in a spotless ERA since the All-Star break and is likely the next man up for saves in the absence of Megill, whose timeline for a return won't become clear until the Brewers shed more light on the severity of his injury. Even if Megill's elbow strain is deemed mild, however, the righty could still be at risk of being shelved beyond the minimum 15 days.

The Reds placed Ashcraft on the 15-day injured list Wednesday due to a right forearm strain.

Ashcraft will be eligible for activation Sept. 9, but even if he's able to recover from the forearm strain with rest and rehab rather than season-ending surgery, he's still likely to need more than 15 days to move past the issue. He'll cede his spot on the 26-man active roster to lefty Nick Lodolo (finger), who was activated ahead of his scheduled start Wednesday versus the Dodgers. Ashcraft had emerged as a key late-inning weapon for the Reds in his first season as a full-time reliever and had been especially effective so far in August, logging 1.59 ERA, 1.24 WHIP and 8:3 K:BB and collecting five holds in 11.1 innings over his 12 appearances on the month.

The Mets recalled Herget from Triple-A Syracuse on Wednesday.

Herget has permitted one earned run with a 1:2 K:BB over 5.1 innings in the majors between Atlanta and New York this season and will fill a low-leverage relief role with the Mets. The club has yet to announce a corresponding roster move.

The Cardinals recalled Granillo from Triple-A Memphis on Wednesday.

St. Louis optioned Granillo to Triple-A on Monday, but he didn't make an appearance for Memphis before he was called back to the big club to join the bullpen as a replacement for John King (back), who landed on the injured list. Granillo is likely to take on a low-leverage role for the Cardinals after logging a 4.82 ERA, 1.50 WHIP and 14:7 K:BB in 18.2 innings through his first 12 relief appearances in the majors.

The Cardinals placed King on the 15-day injured list Wednesday due to a mid-back strain.

King had been on the shelf from July 30 through this past Saturday due to an oblique strain, and despite having not made a relief appearance since being activated Sunday, the left-hander will head back to the IL with a new injury. St. Louis recalled right-hander Andre Granillo from Triple-A Memphis to replace King in the bullpen.

Estrada earned a hold against Seattle on Tuesday, allowing one hit and striking out one batter in one inning.

Estrada entered in a very high-leverage situation, taking the mound with San Diego up by one run the eighth inning. The right-hander allowed a leadoff single but nothing more, getting out of the frame with the lead intact. Mason Miller was used one inning before Estrada, but that doesn't necessarily reflect the Padres' bullpen hierarchy, as Miller was summoned to face the heart of Seattle's order. Nonetheless, Estrada continues to be a trusted late-inning option for San Diego -- he has a career-high 27 holds on the campaign, tied for fourth most in the majors.

Butto picked up a hold over two-thirds of a scoreless inning in Tuesday's 5-2 victory over the Cubs, striking out one.

Butto recorded his third consecutive scoreless outing, throwing four of his seven pitches for strikes after entering with one out in the eighth inning. Over 11 appearances since being traded to the Giants, the right-hander has recorded a 2.61 ERA, 0.87 WHIP and 10:3 K:BB across 10.1 innings. Overall, he owns a 3.45 ERA, 1.29 WHIP and 51:25 K:BB over 57.1 innings in 45 games between the Giants and Mets.

Lucchesi picked up a hold over 1.1 scoreless innings in Tuesday's 5-2 victory over the Cubs, striking out two.

Lucchesi entered the game in the seventh inning and retired all four batters he faced, throwing 13 of his 19 pitches for strikes. The left-hander has struggled in August, though he has recorded back-to-back scoreless outings. Over 10 appearances this month, he has recorded an 8.00 ERA, 1.89 WHIP and 6:4 K:BB across nine innings.
