Gray (elbow) threw a about 30 pitches of live batting practice Wednesday, Bobby Blanco of MASNSports.com reports.

The right-hander continues working his way back from the Tommy John surgery with an internal brace that he underwent in July 2024. Gray may need another live session or two before being cleared for a rehab assignment. Assuming he can avoid a setback, the 27-year-old has a good chance of coming off the injured list for a cameo with the Nationals before the end of the season.

The Mets selected Tong's contract from Triple-A Syracuse on Friday.

Tong is set to make his major-league debut Friday against the Marlins at Citi Field. The 22-year-old posted a 1.43 ERA and 0.92 WHIP with 179 strikeouts in 113.2 innings covering 22 starts between Double-A Binghamton and Syracuse. Tong isn't guaranteed any starts beyond Friday's debut, but a strong performance could convince the Mets he should stick around alongside fellow rookie Nolan McLean.

Brown is slated to start Saturday's game against the Cubs.

Colorado is getting German Marquez (biceps) back from the injured list Friday, but Brown will stick around in the rotation with Antonio Senzatela having been moved to the bullpen earlier this week. After bypassing Triple-A, Brown took the loss in his MLB debut Sunday, surrendering four earned runs on five hits and three walks across 3.2 innings. The rookie won't make for an appealing streaming option while taking on the Cubs at hitter-friendly Coors Field.

Pirates manager Don Kelly said that Burrows won't make a start during this weekend's series versus the Red Sox but should be available in relief, Colin Beazley of the Pittsburgh Post-Gazette reports.

Burrows tossed four shutout innings in his most recent start Saturday to lower his ERA to 4.23, but Kelly said the right-hander's turn through the rotation this week will be skipped in an effort to manage his workload. After being limited to 54.2 innings in 2024 following April 2023 Tommy John surgery, Burrows has already doubled that total in 2025 between his stops with Pittsburgh and Triple-A Indianapolis. The Pirates haven't yet discussed shutting him down for the season, but the team's workload management plan could result in him missing another start or two in September. Burrows could also be deployed as a tandem starter with fellow rookie Bubba Chandler, who has covered four innings in each of his first two MLB relief appearances while piggybacking Graham Ashcraft and Carmen Mlodzinski.

King (knee) will throw at least one more simulated game before being activated off the injured list, AJ Cassavell of MLB.com reports.

King tossed 44 pitches in a three-inning sim game Saturday, so his next sim game will likely take place within the next few days. The right-hander may not need to go on a minor-league rehab assignment before returning to San Diego's rotation, though a concrete plan for his activation hasn't been shared. King has made just one big-league start since May 18 -- he tossed two innings against Boston on Aug. 9 in his return from a shoulder issue but subsequently landed back on the IL due to left knee inflammation.

Sasaki (shoulder) completed 3.2 innings in a minor-league rehab outing with Triple-A Oklahoma City on Tuesday, allowing three runs on five hits and two walks while striking out four batters.

Sasaki's third rehab appearance can best be characterized as uneven; he didn't finish with an impressive stat line but did show some promising signs of improvement. Among the positive aspects of the start were the right-hander's four punchouts (he had combined for just two over 5.1 innings across his first two rehab outings) and his fastball velocity, which reached 98.8 mph, per Fabian Ardaya of The Athletic. Though Sasaki got only two whiffs on his heater, he did get an impressive seven swings-and-misses on the 31 splitters he threw. It remains to be seen what's next for Sasaki -- though he seems to be near-ready to be activated from the IL from a workload perspective, his stuff doesn't yet appear to be sharp enough to get big-league batters out consistently. There also currently isn't any room in the Dodgers' rotation for Sasaki, so he may remain in the minors for multiple more starts to try to iron out his repertoire further.

Holmes allowed four runs (two earned) on five hits and a walk while striking out two over five innings in a no-decision versus the Marlins on Thursday.

Holmes gave up the opening run on a sacrifice fly in the first inning, and it was his own two-out error that allowed the Marlins to build a rally in the third. Holmes has given up 14 runs (12 earned) over 25 innings across his five starts in August, adding a 20:10 K:BB in that span. For the season, he's at a decent 3.60 ERA but with a 1.31 WHIP and lackluster 111:56 K:BB through 142.1 innings across 27 starts. Holmes will get an extra day of rest thanks to Jonah Tong's major-league debut Friday, but it's unclear if the Mets will stick with a six-man rotation across multiple turns. Holmes' next start is projected to be a tough matchup in Detroit, but he could be a candidate for the bullpen if his struggles continue in September.

Mazur allowed two runs on four hits and a walk while striking out two over four innings in a no-decision versus the Mets on Thursday.

Mazur threw 39 of 60 pitches for strikes in this outing. He started off shaky, allowing a two-run double to Brandon Nimmo in the first inning, but Mazur was able to settle in after that. The 24-year-old has given up six runs across 9.2 innings while adding a 7:5 K:BB through two starts in the majors this year, while his 4.36 ERA, 1.30 WHIP and 100:30 K:BB through 107.1 innings at Triple-A Jacksonville are just passable marks. Should the right-hander get another turn through the rotation, he is tentatively lined up for a road start against the Nationals next week.

Quantrill (4-12) allowed nine runs on nine hits while recording no walks or strikeouts over 3.1 innings to take the loss Thursday versus Philadelphia.

Quantrill hasn't been able to reverse his fortunes over his first two starts with Atlanta, though both games have been tough matchups. He left his team debut versus the Mets with calf cramps, and while he was cleared to pitch Thursday, he served up four of the seven homers the Phillies launched in a 19-4 defeat. This is the third time in his last five outings in which Quantrill has given up at least seven runs. Homers haven't been a massive part of the problem for him this season with a total of 22 allowed over 26 starts, but he still has a 6.04 ERA, 1.45 WHIP and 85:35 K:BB through 117.2 innings. Chris Sale (ribs) is set to return from the injured list Saturday, pushing Atlanta to a six-man rotation, and Quantrill's next start is tentatively expected to be in Chicago versus the Cubs.

Nola (3-7) allowed four runs on four hits and three walks while striking out four over six innings to earn the win over Atlanta on Thursday.

Nola wasn't at his best Thursday, but Philadelphia's seven-homer barrage gave him plenty of runway to work with. He's still shaking off the rust after a three-month absence -- he's allowed 13 runs (12 earned) across 14.1 innings since returning from an ankle sprain and a stress fracture in his rib. Between injuries and lackluster performance, highlighted by a 6.47 ERA, 1.50 WHIP and 66:21 K:BB through 64 innings across 12 starts, it's been a season to forget for the 32-year-old right-hander. Nola is projected to make his next start at Milwaukee in a challenging matchup.
