Pomeranz has permitted five hits and one walk while striking out three over 1.1 innings between relief appearances Thursday against the Brewers and Saturday against the Mariners after he previously hadn't pitched since June 14 due to a back soreness.

Pomeranz experienced some back pain during the June 14 outing against the Pirates but was shut down for just a few days before the Cubs made him available out of the bullpen. The lefty was hit around a bit in his last two appearances but still has yet to give up an earned run over his 19.2 innings with the Cubs since being acquired from Seattle on April 21. He owns a 0.92 WHIP and 19:6 K:BB and has collected two wins, one save and four holds over his 22 appearances.

Pagan tossed a perfect inning to convert a save against St. Louis on Sunday.

Pagan entered a 4-1 contest and retired the Cardinals' 3-4-5 batters in order to finish off the win. He struck out four batters in a blown save Saturday but was immediately thrown back into the ninth inning Sunday. Pagan has converted 18 of 21 save chances this season while registering a 3.27 ERA and a 42:11 K:BB.

Paplham (face) was assigned to High-A Fort Wayne on Thursday after being reinstated from Double-A San Antonio's 7-day injured list.

After suffering multiple facial fractures when he was struck by a comebacker in a Cactus League game back in late February, Paplham opened the season on San Antonio's IL. He was cleared to begin a rehab assignment in the rookie-level Arizona Complex League on May 20, and after giving up one earned run in 4.2 innings over four appearances, he was moved to Fort Wayne on June 3. Since reporting to the Midwest League, Paplham has made four more appearances and has struck out six while allowing two earned runs on four hits and one walk in six innings. Though he'll stick around with Fort Wayne for the time being, Paplham could be advanced to San Antonio once the Double-A club has an opening in its bullpen.

Achcraft will start Monday's series opener against the Brewers in Milwaukee, Colin Beazley of the Pittsburgh Post-Gazette reports.

After making his first seven appearances out of the Pittsburgh bullpen following his May 26 call-up from Triple-A Indianapolis, Ashcraft will make his first career major-league start against a red-hot Brewers lineup that has averaged 10.8 runs per contest during its active four-game winning streak. The right-hander has fared well thus far while working in relief, producing a 1.54 ERA and 1.29 WHIP with 10 strikeouts over 11.2 innings. He's maxed out at 40 pitches in those relief outings, but the Pirates could be comfortable with him covering somewhere around 60-to-80 pitches Monday after he had previously built up to six innings during his time in the minors. Even so, the fact that Ashcraft likely won't handle a traditional starter's workload in addition to the tough matchup limits his appeal as a streaming option.

Megill earned the save in Sunday's 9-8 win over the Twins, allowing a hit and a walk while striking out two over 1.1 innings.

The Brewers turned to Megill in the eighth inning after Jared Koenig allowed a pair of two-out singles following a Ty France homer that cut Milwaukee's lead to 9-8. Megill struck out Jonah Bride before working around a Harrison Bader one-out double in the ninth inning to pick up his 17th save this year. Megill's converted his last five save chances, allowing one run while striking out 10 in that span (5.1 innings). His ERA sits at 2.70 on the year with a 1.31 WHIP and 32:14 K:BB across 26.2 innings.

Halvorsen allowed a hit in a scoreless inning and earned a save over Arizona on Sunday. He struck out one batter.

Halvorsen worked around a two-out double by Randal Grichuk to close out the 4-2 victory Sunday. It was Halvorsen's first appearance since blowing a save chance against the Nationals on Thursday. He's now converted six of his nine save opportunities while producing a 4.31 ERA and a 29:14 K:BB through 31.1 innings.

Henriquez earned the save in Sunday's 5-3 win over Atlanta, allowing one hit while striking out one in a scoreless ninth inning.

Henriquez allowed a leadoff single to Alex Verdugo to lead off the ninth, though he got Michael Harris to ground into a double play before striking out Sean Murphy to close out his second save this season. The Marlins have taken a committee approach to the ninth inning this year, and Henriquez has become one of their more trusted relief options. The 25-year-old right-hander has posted a 3.00 ERA with a 1.33 WHIP and 48:16 K:BB across 36 innings this year.

The Phillies optioned Mercado to Triple-A Lehigh Valley on Sunday.

After being called up from Triple-A on June 11, Mercado made three relief appearances during his week-and-a-half-long stay with the Phillies, covering three innings while allowing five earned runs on seven hits and four walks. The Phillies recalled right-hander Alan Rangel from Lehigh Valley to replace Mercado as a lower-leverage, multi-inning option out of the bullpen.

The Phillies recalled Rangel from Triple-A Lehigh Valley on Sunday.

Right-hander Michael Mercado was optioned to Triple-A to make room on the 26-man active roster and in the bullpen for Rangel. The 27-year-old right-hander previously made his MLB debut in a three-inning relief appearance June 7 and will likely serve as a lower-leverage arm during his latest stint with the Phillies.

Treinen (forearm) has advanced to using his entire pitch mix during his throwing progression, per MLB.com.

Treinen resumed playing catch in mid-May, and he then began throwing bullpens in early June. The right-handed reliever recently became eligible to be activated from the 60-day IL, but he probably won't return to the Dodgers' bullpen until at least early July. Trienen will likely be sent out on a minor-league rehab assignment before he's ready to face big-league batters again.
