Arizona manager Torey Lovullo said Saturday that Montes De Oca is set to undergo lower back surgery in the coming days, Alex Weiner of ArizonaSports.com reports.

Montes De Oca was placed on the 15-day injured list earlier in the week due to elbow inflammation, but his back was apparently a greater concern. A timeline for his return could be released once surgery is completed, but Lovullo noted that Montes De Oca could be sidelined for the rest of the season. He made just one appearance out of the Arizona bullpen before landing on the IL.

Junk (1-0) picked up the win Saturday, scattering two hits over 5.2 scoreless innings of relief in a 4-3 victory over the Nationals. He struck out four without walking a batter.

The 29-year-old right-hander was the fourth Miami pitcher to take the mound on the afternoon, entering the game with one out and two men on in the third inning. Junk nearly tossed the equivalent of a quality start as the bulk reliever on just 64 pitches (42 strikes), retiring the first 10 batters he faced and not allowing a runner to get into scoring position. Junk has made five appearances this season, all out of the bullpen, and posted an impressive 2.78 ERA, 1.01 WHIP and 20:2 K:BB in 22.2 innings. The Marlins are short a starting pitcher at the moment with Ryan Weathers (lat) and Max Meyer (hip) on the injured list, and they don't get another off day until June 23, so Junk seems likely to plug that rotation hole at some point next week, either in a traditional start or as a primary pitcher once again.

Hoeing (shoulder) began a new rehab assignment June 7, per MLB.com.

Hoeing first began a rehab stint in May, but he wasn't adequately built up by the end of that assignment, so he began another one shortly thereafter. The right-hander has thus far appeared in three games with Triple-A El Paso during his second minor-league stint, allowing three runs with a 5:2 K:BB over 3.1 innings. Hoeing has yet to pitch on back-to-back days, however, and that may be a requirement before San Diego is ready to activate him.

Palencia worked around a hit to toss a scoreless ninth inning and earn the save in Saturday's 2-1 win over the Pirates. He struck out two.

A day after seeing Ryan Pressly earn a save while he worked the eighth inning for a hold, Palencia was back as the closer Saturday. Pressly, meanwhile, worked the seventh after starter Matthew Boyd logged six solid innings. Palencia now has six saves this season in seven chances, and he lowered his ERA to a sparkling 1.73. It appears that the closer situation may remain fluid in Chicago, with both Palencia and Pressly getting opportunities for the time being. That gives both players fantasy value, though it does limit their ceilings.

McDaniels cleared waivers Saturday and was returned to the Dodgers, Jeff Fletcher of The Orange County Register reports.

McDaniels turned in a 5.91 ERA and 1.97 WHIP across 10.2 innings before a biceps injury sent him to the injured list in May. The Angels designated McDaniels for assignment Monday after he was reinstated from the IL, and he will now return to the organization he began his professional career with before he was selected in the Rule 5 Draft over the winter. He will most likely report to Triple-A Oklahoma City and serve as bullpen depth for the Dodgers.

The Red Sox traded Van Belle to the Reds on Saturday in exchange for cash.

Boston designated the 28-year-old righty for assignment Wednesday to clear room for Jorge Alcala. Van Belle will retain a 40-man roster spot upon switching organizations, though he will report to Triple-A Louisville to begin his time with the Reds. However, with a 2.47 ERA and 1.06 WHIP across 51 innings in the minors this year, it may not be long before he gets his chance to debut in the big leagues.

Phillips (1-0) was credited with the win Friday, striking out one in a scoreless two-thirds of an inning against the Marlins.

Starter Edward Cabrera lasted only three innings and left the mound with Miami ahead 6-2, and the official scorer gave the win to Phillips after he recorded the first two outs in the fourth. The 27-year-old has worked in a low-leverage role all season, posting a 4.59 ERA, 1.35 WHIP and 19:9 K:BB through 33.1 innings over 23 appearances with zero saves or holds.

Lee gave up a hit and struck out one in a scoreless ninth inning Friday during a 12-4 win over the Rockies.

While it seems like a low-leverage spot, Lee was warming up to handle a save chance in the ninth after Pierce Johnson had entered the game in the fifth inning and Raisel Iglesias had collected his first hold in the eighth. Atlanta tacked on five insurance runs in the bottom of the eighth to deny Lee a shot at his second save of the year, however. The southpaw has been impressive in 2025, posting a 2.10 ERA, 0.90 WHIP and 30:8 K:BB over 30 innings, and he appears to be part of a high-leverage committee at the moment with Iglesias and Johnson. Who gets saves from that group will likely come down to matchups, and who is available for any particular game.

Iglesias gave up a hit and struck out one in a scoreless eighth inning Friday to record his first hold of the season in a win over the Rockies.

The right-hander was brought in to protect a 7-4 lead and got the job done on 12 pitches (eight strikes). Iglesias hasn't collected a save since May 16, and while Atlanta manager Brian Snitker indicated over the weekend that he was no longer the team's primary closing option, he didn't say the veteran reliever would be completely removed from the late-inning mix. If Iglesias can string together a few more sharp appearances, he could reclaim the job. Dylan Lee was in line for the save opportunity Friday before Atlanta erupted for five insurance runs in the bottom of the eighth inning.

The Nationals recalled Loutos from Triple-A Rochester on Saturday.

With Andrew Chafin (hamstring) headed for the IL, Loutos will be called upon to replenish the Nationals' bullpen depth. The 26-year-old was claimed off waivers from the Dodgers on Tuesday and has given up five runs over 5.1 innings across his MLB career.
