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.

The Marlins optioned Simpson to Triple-A Jacksonville on Wednesday.

One day after being torched for seven runs while retiring just one batter in an 11-2 loss to Atlanta, Simpson finds himself back in the minors. Seth Martinez and Freddy Tarnok were called up from Jacksonville to supplement the Marlins bullpen.

The Marlins recalled Tarnok from Triple-A Jacksonville on Wednesday.

Tarnok has been lights out at Jacksonville lately, tossing 14.1 scoreless innings with an 18:6 K:BB across his last 10 appearances. The 26-year-old could work his way into high-leverage situations but also offers the ability to go multiple innings.

Wicks tossed a scoreless eighth inning in Tuesday's 5-2 loss to the Giants.

Wicks was making his first MLB appearance since July 11 when he allowed six runs on 10 hits over three innings. The lefty was briefly called up from Triple-A Iowa on Aug. 19 to serve as the 27th man for a doubleheader, but he didn't see any game action. Wicks has struggled in the majors the last two seasons, and he'll likely see low-leverage work for however long he sticks with the Cubs this time around.

Rogers, who tossed a scoreless inning of relief in Tuesday's loss to the Giants, has allowed just one run and struck out 11 batters across 7.1 innings since joining the Cubs at the trade deadline.

Rogers allowed a solo home run back on Aug. 18, but outside of that, he's been flawless with his new team. The veteran lefty has quickly earned trust as a high-leverage setup option in front of closer Daniel Palencia. For the season, Rogers has a 2.23 ERA, 1.36 WHIP and 10.0 K/9. With a career 10.5 K/9, he should be expected to keep racking up strikeouts at a high rate the rest of the year.
