Munoz struck out one in a perfect ninth inning Wednesday to record his eighth save of the season in an 8-5 win over the Red Sox.

The right-hander continued his dominant start to the season. Munoz has yet to allow a run in 12 appearances, posting a 0.83 WHIP and 15:5 K:BB, and his eight saves lead the American League.

Miller collected the save in Wednesday's win over the Rangers after allowing one hit in a scoreless ninth inning, striking out three.

The hard-throwing right-hander overwhelmed the first two batters he faced, retiring them on just seven pitches, but a slumping Joc Pederson did tag him for a double Wednesday. Miller has still been spectacular to open the season, producing a 0.62 WHIP and 17:1 K:BB across eight scoreless frames. Miller has also gone a perfect 7-for-7 on save opportunities, giving him a strong grip on the closer's role for the Athletics.

Wilson came away with the no-decision in the White Sox's 6-3 loss to the Twins on Wednesday. He allowed one run on five hits and three walks while striking out two in 2.2 innings.

The right-hander made his first start of the season Wednesday with Martin Perez (elbow) going on the 60-day injured list earlier in the week. Wilson wasn't able to make it out of the third inning, tossing 55 pitches (30 strikes) before being lifted for Brandon Eisert. Wilson started the season in the bullpen, but he could be used in the rotation unless the White Sox make a move to add a starter via the minor leagues or trade. If he sticks in the rotation, Wilson is tentatively slated to start next week at home against the Brewers.

Coulombe earned the save in Wednesday's 6-3 win over the White Sox, striking out one batter without allowing a walk or hit in a scoreless ninth inning.

Usual closer Jhoan Duran needed 32 pitches to collect the save Tuesday, so Coulombe got the call for the ninth inning of Wednesday's game to preserve a three-run lead. Coulombe needed just 12 pitches (seven strikes) to get through the frame, highlighted by a six-pitch strikeout of Bobby Dalbec. Coulombe hasn't allowed a run over his first 11 outings of the season and has an 0.41 WHIP and 6:1 K:BB across 9.2 innings.

Gusto (3-1) earned the win against the Blue Jays on Wednesday, allowing one run on three hits and one walk while striking out six over 5.2 innings.

Gusto yielded only four base runners in Wednesday's start, with his lone blemish coming in the fourth inning when he gave up an RBI double to George Springer. Gusto generated 12 whiffs on a season-high 80 pitches (47 strikes) and was one out shy from recording his first career quality start. He's gone five innings in each of his last two outings, and for the season he's registered a 2.78 ERA, 1.10 WHIP and 23:4 K:BB over 22.2 innings. He's lined up to face the Tigers at home next week.

Hader allowed one hit and one walk in a scoreless ninth inning to earn the save in Wednesday's 3-1 win over the Blue Jays. He struck out two batters.

Hader put himself in a bit of hot water when he gave up a walk and a double, but he bounced back to fan Alejandro Kirk before getting Myles Straw to fly out to center field to close out Wednesday's contest. He needed 23 pitches (16 strikes) to get through the ninth inning, but with an off-day Thursday the 31-year-old southpaw should be available for Friday's series opener against the Royals. Hader has not yielded a run since Opening Day against the Mets and boasts a 0.69 ERA, 0.69 WHIP and 17:3 K:BB over 13 innings.

The Rangers designated Pennington for assignment Wednesday, Shawn McFarland of The Dallas Morning News reports.

The Rangers selected Nick Ahmed to the active roster Wednesday to make up for Corey Seager's (hamstring) move to the IL, leaving Pennington as the odd man out of a spot on the 40-man. The 27-year-old southpaw hasn't appeared in a minor-league game yet this season, though other teams may be willing to pick him up off waivers based on his career 2.83 ERA and 1.17 WHIP at the Triple-A level.

Ellard (hamstring) will begin a rehab assignment with Triple-A Charlotte on Thursday, Scott Merkin of MLB.com reports.

Ellard landed on the 15-day injured list April 11 due to a right hamstring injury, and he's progressed enough in his recovery to embark on a rehab assignment with Charlotte. He logged a 5.40 ERA, 1.00 WHIP and 6:4 K:BB across five innings out of the White Sox's bullpen before landing on the IL.

Imaging done on Marsh's right shoulder Tuesday was inconclusive, so he'll head back to Kansas City for further evaluation, Anne Rogers of MLB.com reports.

Marsh has been shut down from throwing since April 5 after suffering a setback in his shoulder, and he'll now have to wait a bit longer before receiving a verdict on whether he can resume his rehab program. If his next round of testing delivers promising results, the Royals aim to have him throwing again sometime this weekend.

The Angels optioned Darrell-Hicks to Triple-A Salt Lake on Wednesday.

After joining the big-league squad April 11, Darrell-Hicks gave up five earned runs across 6.2 innings while striking out four batters and walking four. His poor performance will result in him heading back to the minors, though he hasn't exactly stood out in Triple-A either (9.45 ERA and 1.61 WHIP through 6.2 IP). Victor Mederos was recalled from High-A Tri-City in a corresponding move.
