Reds president of baseball operations Nick Krall said Friday that Greene has been diagnosed with a partial UCL tear in his right elbow and will undergo surgery next week, Brian Giesenschlag of Reds Live reports.

The exact nature of the procedure will not be known until the operation is performed. Greene previously had Tommy John surgery in 2019 and underwent surgery in March to have bone chips removed from his elbow. Even if Greene doesn't require another full Tommy John repair, he will be in danger of missing a large portion of the 2027 season. The 27-year-old made only five starts this year after being limited to 19 starts in 2025.

Alvarez is slated to start Saturday's game against the Reds at Nationals Park.

After being called up from Triple-A Rochester on Monday, Alvarez will wind up getting a two-start week. The 27-year-old southpaw delivered a quality start Monday against the Phillies with two earned runs allowed over 6.1 innings, and he's compiled a 3.94 ERA, 1.45 WHIP and 63:31 K:BB over 64 innings through his first 16 appearances (eight starts) with Washington. Alvarez should have a good chance at sticking around in the rotation spot for the rest of the season after the Nationals designated right-hander Zack Littell for assignment earlier in the week.

Stock is listed as the Mets' probable starting pitcher for Saturday's game in Pittsburgh.

The 36-year-old righty will be awarded another turn through the rotation after a solid showing last Sunday, when he held the Marlins to one run on three hits and no walks while striking out four over five innings in his first big-league start since 2021. The Mets thinned their starting depth by dealing away Clay Holmes (fibula) and Freddy Peralta at the trade deadline, and with prospects Jonah Tong and Jack Wenninger struggling of late at Triple-A Syracuse, Stock doesn't appear to be facing any imminent threats for his spot in the rotation.

Perales is a pitcher the Nationals believe is nearly ready to make his big-league debut, Spencer Nusbaum of The Athletic reports.

Acquired from Boston in the offseason, Perales had a bumpy start to the season after completing his recovery from Tommy John surgery, but over his last eight starts for Triple-A Rochester he's put together a 2.79 ERA, 1.29 WHIP and 41:25 K:BB in 38.2 innings. The 23-year-old right-hander is still working to improve his control and his stamina, but Perales has elite raw stuff headlined by a four-seamer that averaged 98.5 mph and a split-finger pitch that's generated a 42.2 percent whiff rate in 2026. A late-season stint with the Nationals would put Perales on track to win a spot in the rotation next spring.

Early (elbow) will not be sent for an MRI after he felt some minor forearm tightness during a live batting practice session Tuesday, Spencer Nusbaum of The Athletic reports.

Manager Blake Butera indicated the organization wasn't overly concerned about Early's health, but the setback might have been the only excuse the Nationals needed to rule the southpaw out from pitching in the majors again this season. Acquired in the Curtis Mead (wrist) deal, Early had a 3.44 ERA, 1.25 WHIP and 93:34 K:BB through 91.2 innings for the Red Sox earlier this year. He last saw game action June 30 before landing on the IL with elbow inflammation.

The Mets outrighted Conley to Double-A Binghamton on Thursday.

Conley didn't make an appearance for the Mets before being removed from their 40-man roster. He will remain in the organization after passing through waivers unclaimed.

Mahle will make his Atlanta debut with a start Friday against the Yankees in New York.

Acquired from the Giants over the weekend, Mahle will slot into the back end of the Atlanta rotation as a replacement for Reynaldo Lopez (knee), who landed on the injured list Sunday. Mahle took advantage of a favorable home park in San Francisco by delivering a 2.65 ERA and 1.14 WHIP over nine starts, but those ratios swelled to a 8.04 ERA and 1.69 WHIP in nine starts away from Oracle Park. The right-hander profiles as a high-risk fantasy option Friday at Yankee Stadium, which is notoriously friendly for left-handed power hitters like Ben Rice, Jazz Chisholm and Luis Garcia.

Drake (0-1) took the loss against San Diego on Thursday, allowing three runs on six hits and one walk while striking out one batter over 3.2 innings.

Though he walked only one batter, Drake threw just 46 of 82 pitches for strikes. Three of the six hits the rookie southpaw allowed were doubles, and he didn't miss many bats, recording only three whiffs and one strikeout. Drake logged five innings in his first MLB start July 21 against the A's, but since then each of his three outings has lasted four frames or less. Michael Soroka (glute) recently kicked off a rehab assignment, and Drake is currently the most likely Arizona hurler to be the odd man out of the rotation when Soroka is ready to return.

Buehler allowed one run on six hits and one walk while striking out three batters over four innings in a no-decision against Arizona on Thursday.

Buehler put two runners on base in the first inning but escaped without giving up any runs. He dodged trouble again in the third, when he allowed four straight hits but surrendered only one run. All of that traffic resulted in Buehler needing 76 pitches to get through four frames, and he didn't come back out for the fifth inning. It was the second straight outing during which Buehler has completed less than four frames, though he's yielded a tolerable four runs across 8.1 innings during that span. He's managed to hang onto a rotation spot despite a 5.07 ERA through 23 starts on the season, but the looming returns of Nick Pivetta (forearm) and Joe Musgrove (elbow) -- each of whom recently began a minor-league rehab stint -- could spell the end of Buehler's time as a starter.

Junk (5-7) took the loss against Atlanta on Thursday, allowing two runs on five hits and one walk while striking out one batter over three innings.

Junk threw 47 pitches (26 strikes) before a rain delay held up the game for over an hour. That was enough for Marlins manager Clayton McCullough to decide not to put Junk at risk of an injury by sending him back out to the mound when play resumed. The two runs Junk gave up were on a home run by Ronald Acuna, though the homer was the result of two Marlins outfielders colliding while trying to make the catch and popping the ball over the wall. While this was Junk's shortest outing of the campaign, that obviously comes with an asterisk due to the impact of the weather. The right-hander's arm should at least be relatively fresh the next time he takes the mound, which is projected to be in a matchup versus Pittsburgh.
