Atlanta designated Petersen for assignment Sunday.

The right-hander was optioned to Triple-A Gwinnett in late June and has now also lost his place on the 40-man roster. Petersen could remain with Gwinnett if he passes through waivers unclaimed.

Atlanta optioned Hernandez to Triple-A Gwinnett on Sunday.

The right-hander enters Sunday having pitched three of the previous four days, so he'll head to the minors in favor of a fresh bullpen arm in right-hander Wander Suero, who was called up from Gwinnett. Hernandez has recorded seven holds with a 2.10 ERA, 1.30 WHIP and 30:24 K:BB across 30 innings this season, so he's a strong bet to rejoin Atlanta's bullpen during the second half of the campaign.

Atlanta selected Suero's contract from Triple-A Gwinnett on Sunday.

The right-hander inked a minor-league deal with Atlanta during the offseason and will join the big-league roster for the final game before the All-Star break. Suero pitched well in 33 outings for Gwinnett with a 1.50 ERA, 1.00 WHIP and 49:10 K:BB across 36 innings.

The Nationals recalled Lara from Double-A Harrisburg on Sunday.

Lara will provide some extra bullpen coverage in Sunday's series finale with the Brewers after the Nationals burned through four relievers Saturday. Washington optioned Shinnosuke Ogasawara to Triple-A Rochester following Saturday's game, and it's possible Lara ends up getting a look in the rotation to begin the second half. The 22-year-old right-hander has turned in a 7.50 ERA and 2.00 WHIP over 36 innings in the minors this season but was effective in his MLB debut July 2, holding the Tigers scoreless while striking out four over three innings.

The White Sox reinstated Booser (shoulder) from the 15-day injured list and optioned him to Triple-A Charlotte on Sunday.

Initially placed on the IL on June 20 due to a left shoulder strain, Booser will stick around with Charlotte after he completed a two-appearance rehab assignment with the affiliate earlier in the week. Prior to being shut down with the injury, Booser had been working in a middle relief role for Chicago, logging one win, seven holds and one save while pitching to a 5.11 ERA and 1.42 WHIP over 24.2 innings.

The Mets optioned Warren to Triple-A Syracuse on Sunday.

After serving as the Mets' 27th man in Thursday's doubleheader with the Orioles, Warren was returned to Triple-A on Friday before being recalled later that day. He didn't end up making an appearance over the last two days and will once again return to the minors, this time to clear a spot on the active roster for Sean Manaea (elbow/oblique).

Miller walked one and struck out two in a scoreless ninth inning Saturday to record his 18th save of the season in a 4-3 win over the Blue Jays.

After walking Joey Loperfido to lead off the frame, Miller buckled down and fanned Ernie Clement and George Springer to wrap up the victory. The flamethrowing righty hit triple-digit mph with 10 of his 18 pitches (nine strikes), and on the season he sports a 4.15 ERA, 1.07 WHIP and 56:17 K:BB through 34.2 innings while converting 18 of his 21 save chances.

Detmers probably won't be moving into the Angels' rotation despite the demotion of Jack Kochanowicz to the minors, per Aaron Coloma of SI.com.

Kochanowicz and Detmers battled for the fifth starter role in spring training, with the former ultimately getting the role. However, Kochanowicz has struggled to a 6.03 ERA over 19 starts and was sent down to Triple-A Salt Lake on Friday. When asked ahead of that demotion whether Detmers could be an option to move from the bullpen into a starting role, interim manager Ray Montgomery stated, "I would hate to say no to anything, but I don't think that's going to happen." Detmers has thrived in a setup role -- though he has posted a mediocre 4.15 ERA on the campaign, that is largely due to a horrific three-outing stretch in late April and early May during which he allowed 12 runs over one-third of an inning. Since then, the lefty has emerged as one of the Angels' top high-leverage options, posting a 1.24 ERA, 1.17 WHIP and 38:13 K:BB over 29 frames spanning 28 appearances while recording eight holds and two saves.

Rogers threw a scoreless ninth inning in Saturday's 2-1 loss to the Dodgers, allowing one hit.

Though he gave up one single Saturday, Rogers also induced three groundouts to end the frame efficiently, throwing eight of his 10 pitches for strikes. The right-hander hasn't allowed an earned run in six consecutive appearances and now owns a 1.55 ERA, 0.78 WHIP and a 34:4 K:BB across 46.1 innings in 48 outings.

The Orioles recalled Wolfram from Triple-A Norfolk on Sunday.

The left-hander was up with Baltimore for Thursday's doubleheader against the Mets and is back with the club for the final game of the first half Sunday. Wolfram has appeared in three games for the Orioles this season and has given up two earned runs with a 5:2 K:BB over 3.1 innings.
