The Dodgers are expected to call up Diaz from Triple-A Oklahoma City ahead of Tuesday's game against the Brewers, Fabian Ardaya of The Athletic reports.

The former Reds closer was acquired by the Dodgers in late May and has made just six appearances for Oklahoma City since being traded, giving up five earned runs with a 3:7 K:BB over 4.2 innings. Diaz should fill a low-leverage role early on for the Dodgers but could work his way into higher-leverage spots. However, the 28-year-old's recent body of work at Triple-A doesn't provide much evidence that he's rediscovered his All-Star form.

The Mets designated Pop for assignment on Tuesday.

The right-hander inked a major-league contract with New York at the start of July after being cut loose by Seattle, but the Mets also decided to move on after just one appearance. Pop gave up three runs over 1.1 innings during his brief time in Queens and has surrendered 11 earned runs across 6.2 frames overall in the majors this year.

The Mets signed Fernandez to a minor-league contract Tuesday.

Fernandez had been at Triple-A Omaha in the Royals organization, where he held a 4.93 ERA and 53:26 K:BB over 38.1 frames. The 28-year-old hasn't seen any action at the big-league level since 2022 but will give the Mets some experienced relief depth at Triple-A Syracuse.

The Nationals sent Ribalta (biceps) to Double-A Harrisburg on Tuesday to begin a rehab assignment, Bobby Blanco of MASNSports.com reports.

Ribalta has been sidelined since mid-April with a right biceps strain but has been cleared for rehab games following a lengthy absence. Given how long he's been out, Ribalta is likely to require a fairly long rehab assignment before being considered for reinstatement from the 15-day injured list.

Arizona manager Torey Lovullo said after Monday's 6-3 win over the Padres that Miller (forearm) is scheduled to undergo an MRI, Jesse Friedman of GoPHNX.com reports.

Miller wasn't known to be nursing an injury before the Diamondbacks surprisingly placed him on the 15-day injured list Monday due to a right forearm strain. The extent of the injury won't be fully known until his MRI results are in, but Lovullo noted that his concern level for Miller was "not low, something right in the middle." Before hitting the shelf, Miller had settled in as the Diamondbacks' closer after A.J. Puk (elbow) and Justin Martinez (elbow) required season-ending Tommy John surgeries, notching 10 saves while compiling a 1.98 ERA and 0.96 WHIP over 36.1 innings. While Miller was out Monday, Kevin Ginkel stepped in to notch the save, though Lovullo suggested that the Diamondbacks' closer situation will be dictated by matchups until Miller returns, per Jody Jackson of Bally Sports Arizona.

Doval recorded a save against the Phillies on Monday, walking one batter in a hitless and scoreless inning.

Doval was called upon in the ninth frame to protect a two-run lead. He walked the first batter in the inning but faced the minimum amount of hitters thanks to a game-ending double play. This was a promising outing after Doval gave up nine runs (eight earned) over his previous five appearances spanning 5.2 innings. He's remained the Giants' primary closer despite that rough stretch and has succeeded on 14 of 18 save opportunities on the campaign.

Ginkel earned a save against the Padres on Monday, walking one batter in a hitless and scoreless ninth inning.

Ginkel got the call in the ninth frame with Arizona holding a three-run lead, and he got the job done despite issuing a leadoff walk. It was just the second save of the season for Ginkel, but it's telling that he was chosen for the team's first save opportunity after Shelby Miller (forearm) landed on the injured list Monday. It remains to be seen how the Diamondbacks will handle the closer role while Miller is out of action, but Monday's usage suggests that Ginkel will be in the mix and may be the top ninth-inning option for the time being.

Bender recorded one out to pick up the save in Monday's 5-1 win at Cincinnati.

After Miami reliever Lake Bachar, who collected a save Saturday against Milwaukee, failed to collect a three-inning save this time out by finishing the ninth inning, Bender entered with two outs and two runners on to wrap things up. The 30-year-old required only three pitches to fan Reds outfielder Austin Hays and notch his second save of the season. The Marlins bullpen has been difficult to navigate, with seven different relievers tallying saves so far, led by Calvin Faucher (eight) and Ronny Henriquez (five). Henriquez remains the favorite to garner future chances based on his recent usage, but Bender, with his 2.11 ERA in 38.1 innings, could enter the mix as well.

X-rays on Ashby's left hand came back negative after being struck with a comebacker during Monday's appearance against the Dodgers, Adam McCalvy of MLB.com reports.

Ashby took a comebacker off his pitching hand during the seventh inning but managed to remain in the game. Further imaging revealed that he avoided a significant injury, though he should be considered day-to-day until the club has a chance to re-evaluate and clear the southpaw to return to the mound.

Junk (3-1) earned the win in Monday's contest at Cincinnati, allowing one unearned run on one hit and two walks over six innings. He struck out three.

The Miami righty was in complete control of this game, limiting the Reds lineup to just one single in this 82-pitch outing. The lone blemish on Junk's performance came on a Tyler Stephenson sacrifice fly in the second. Junk has impressed since moving into the Marlins rotation June 20, pitching to a 3.48 ERA, 1.06 WHIP and 16:2 K:BB in 20.2 frames across four starts. The 29-year-old currently projects to make his next start at Baltimore this weekend.
