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.

Houston Astros starting pitcher Luis Garcia (elbow) could start a game in the complex league this weekend, manager Joe Espada said before Tuesday's game against the visiting Colorado Rockies. That would be the beginning of a minor-league rehab assignment for Garcia, who's entering the closing stages of his recovery from last season's Tommy John surgery. He'll likely spend around 30 days on assignment before the Astros consider reinstating him from the 60-day injured list, but Garcia is a name to watch on fantasy waiver wires ahead of the mid-July All-Star break. In 27 innings last year, the 27-year-old Venezuelan right-hander registered a modest 4.00 ERA, 1.29 WHIP, and 31:10 K:BB in Houston's rotation.

Arizona Diamondbacks catcher Gabriel Moreno (thumb) will catch Zac Gallen's bullpen session on Thursday. Manager Torey Lovullo said before Tuesday's game against the visiting Minnesota Twins that he's optimistic Moreno will be able to return after missing the minimum 10 days on the injured list. Moreno sprained his left thumb on a foul tip in this past Friday's contest against the Philadelphia Phillies, but it sounds like he could return to the D-backs during the first week of July and skip a brief minor-league rehab assignment. Fantasy managers in shallow leagues should be able to find better stashes than the 24-year-old contact-hitting backstop, who's slashing an uninspiring .230/.313/.346 with three home runs, 11 doubles, 26 RBI, and 23 runs scored in 217 trips to the plate as Arizona's everyday catcher in 2024.

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 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.
