Atlanta Braves starting pitching prospect Cade Kuehler is being promoted to High-A Rome, according to MiLB Central. Kuehler joined the Atlanta organization as the 70th overall pick in last year's MLB Draft. Kuehler got a small seven-inning taste of Single-A ball last season and allowed just one hit with a 4:8 BB:K ratio. The Campbell University product remained with Single-A Augusta to open the 2024 campaign and held a strong 2.52 ERA, 1.22 WHIP, and a 20:44 BB:K ratio through 50 innings. After posting a poor 4.82 ERA and 1.71 WHIP through May, the 22-year-old responded well in June where he held a stellar 0.90 ERA and 1.10 WHIP across four starts. Kuehler is ranked as the eighth-best prospect in a deep Atlanta pitching farm and is projected to reach the majors in 2026.

Tampa Bay Rays starting pitching prospect Trevor Martin is being promoted to Double-A Montgomery, according to MiLB Central. Martin was selected in the third round from Oklahoma State in the 2022 MLB Draft. He spent the entirety of the 2023 season with Single-A Charleston and posted a 3.52 ERA, 1.21 WHIP, and a 41:131 BB:K ratio in 110 frames. He opened this season in High-A and once again averaged over a strikeout per inning with 88 in 72 frames. He held an improved 2.88 ERA and 1.10 WHIP. The 23-year-old has been exceptional through June with a 1.80 ERA and 0.90 WHIP, which resulted in his promotion. Martin is ranked as the 19th-best prospect in Tampa Bay on MLB.com and remains on track to meet his 2025 major league ETA.

Minnesota Twins starting pitching prospect David Festa could be nearing his major league debut, according to Dan Hayes of The Athletic. Recently, the Twins placed right-hander Chris Paddack (forearm) on the 15-day injured list with right forearm fatigue, which opens a spot in the starting rotation. Festa has posted a 3.77 ERA, 1.29 WHIP, and a 24:87 BB:K ratio through 59 innings in his first extended look at Triple-A ball this season. The Seton Hall product has struck out ten batters on three occasions and eight batters twice, which shows his elite strikeout potential. The 24-year-old right-hander was already a candidate to reach the major leagues this season but could now be promoted much sooner than expected due to Paddack's injury. Festa is worth stashing in all standard leagues as he could provide high-upside strikeout production when he receives the call.

Tampa Bay Rays starting pitcher Shane McClanahan (elbow) has increased his throwing distance to 135 feet on flat ground. Manager Kevin Cash said on Monday that McClanahan is "doing well," but he is still unlikely to pitch for the Rays this season. The 27-year-old star left-hander underwent Tommy John surgery on Aug. 21 of last year, his second time having the procedure, though it's worth mentioning that the two-year deal he inked with Tampa Bay in January to avoid arbitration included escalators for his 2025 to account for the possibility of a late-season return in 2024 if his rehab permits it. In 115 innings in 2023, McClanahan went 11-2 with a 3.29 ERA and 1.18 WHIP with 121 strikeouts and 41 walks.

Seattle Mariners infield prospect Michael Arroyo is being promoted to High-A Everett. The 19-year-old has taken a significant step forward at Single-A Modesto this season. He held a modest .234/.389/.373 slash line with two home runs, 23 RBI, and five stolen bases in 57 games at Single-A last season but posted a much improved .279/.404/.500 line this season through a similar 60 games. He launched 11 home runs, tallied 49 RBI, and stole eight bases. The utility infielder has logged games at shortstop, the hot corner, and the keystone all throughout his minor league career but has begun to find a home at second base this season with a career-high 44 games played there. Arroyo is ranked as the ninth-best prospect in a deep Seattle system on MLB Pipeline and remains on track to reach the majors in 2027.
