Atlanta Braves relief pitching prospect Hayden Harris is being promoted to Triple-A Gwinnett, according to MiLB Central. Harris has progressed through the Braves system very quickly and is now just one stop away from the major leagues. The 25-year-old began last season in Single-A Augusta and eventually finished the season with Double-A Mississippi. After posting a poor 9.72 ERA in Single-A, the southpaw improved as the season progressed and was able to post a strong 2.83 ERA,1.26 WHIP, and a 17:50 BB:K ratio in 35 frames at Double-A. He opened the 2024 season at Double-A and built off that momentum with a stellar 1.74 ERA, 1.26 WHIP, and a 9:34 BB:K ratio in 20 innings. He allowed just one earned run through the first two months of the campaign with 29 total punchouts. Even though he struggled through June, the Braves believe Harris is ready for the top level of the minors. He is a name to keep a close eye on in NL-only formats, as he could provide a strong source of holds if he joins the major league roster later this summer.

With New York Mets outfielder Starling Marte (knee) sidelined, the obvious candidates on the roster to see more action in the outfield are DJ Stewart and Tyrone Taylor. Second baseman Jeff McNeil could see more time in the outfield, too, which would open up the possibility of moving an infielder up from Triple-A Syracuse. The Mets have used Jose Iglesias often against lefties to spell the slumping McNeil at the keystone. Brett Baty, who has played three games for Syracuse at second since his demotion last month, and prospect Luisangel Acuna are infielders on the 40-man roster. The only other outfielder on the 40-man roster is speedster Duke Ellis, but he's only played eight major-league games. Ben Game and Trayce Thompson are other options not on the 40-man roster for the Mets.

Atlanta Braves pitching prospect Domingo Gonzalez will make his Triple-A debut, according to Chase Ford of MiLB Central. Gonzalez has been in the Atlanta system since 2021 after making his minor league debut in the Pittsburgh organization a few years prior. Gonzalez has bounced between a start and bullpen role all throughout his minor league career but has begun to find his footing in a high-leverage role this season. In 23 frames with Double-A Mississippi, the right-hander has tallied a career-high seven saves with a solid 2.28 ERA, 0.80 WHIP, and a 9:38 BB:K ratio. This is a stark contrast compared to the 4.19 ERA, 1.45 WHIP, and 33:76 BB:K ratio he held across 53 frames at Double-A last season. Gonzalez should be expected to maintain his high-leverage role at Triple-A and could become a vital piece of the Braves bullpen in the second half of the season.

Miami Marlins left-hander Ryan Weathers (finger), who is rehabbing in Jupiter, Fla., will be evaluated for throwing in a few days. Weathers was pulled after giving up a two-run home run to Cleveland Guardians shortstop Brayan Rocchio on the 40th pitch of his June 7 start and landed on the injured list with a left index-finger strain. If the 24-year-old southpaw can ramp up his throwing program quickly, there's a chance he could rejoin Miami's starting rotation before the All-Star break in mid-July. In his first full season with the Fish this year, Weathers has looked pretty good, going 3-5 with a 3.55 ERA (3.91 FIP) and 1.14 WHIP with a 67:20 K:BB in 71 innings over his 13 starts. His 22.5% strikeout rate is right in line with his career-high 23% mark in 2023. When healthy, he has clear streaming appeal in mixed fantasy leagues.

Miami Marlins right-hander Sixto Sanchez (shoulder), who was rehabbing with the team in Kansas City as of Monday, will be evaluated for a bullpen session in a few days. Sanchez has been asymptomatic while throwing after experiencing a big dip in velocity in his May 31 start against the Texas Rangers. He was placed on the injured list on June 2 with right-shoulder inflammation. Sanchez has had a history of major shoulder problems, including two surgeries that caused him to miss three major-league seasons from 2021-23. It's good news that the 25-year-old could resume throwing bullpen sessions, but the Fish will surely be cautious with him given his injury history with his right shoulder. The Dominican hurler will need a minor-league rehab assignment, too, so it's likely that he won't be an option for Miami's rotation until after the All-Star break. He hasn't been much of a fantasy option in 2024, going 0-3 with a 6.06 ERA and 1.59 WHIP with just 17 K's in 35 2/3 frames.
