Seattle Mariners starting pitching prospect Kade Anderson tossed another shutout in his most recent outing at Double-A and remains the most dominant pitcher in the minor leagues. On August 7, Anderson tossed 5 1/3 innings, allowing just three hits, with no walks, no runs, and nine punchouts. This extended his current shutout streak to 15 innings (three starts). During this stretch, the former LSU star has posted a 0.47 WHIP with a near-perfect 20:2 K:BB. On the season, the southpaw has held a 1.13 ERA with a 0.65 WHIP across his first 87 2/3 professional innings. While Luis Castillo's move to Chicago did make Anderson's path to the majors clearer, the team has indicated he will remain a starter once promoted, so he may need to wait for another injury, as Seattle currently has a full staff. However, his upside on a per-game basis remains elite, and managers should continue to view him as a priority stash option across all league types.

Minnesota Twins outfield prospect Walker Jenkins turned in another dominant effort at Triple-A St. Paul as his MLB debut continues to loom closer. On August 8 (Saturday), Jenkins went 2-for-5 with a triple and a stolen base. Over his last 10 games at the top club in the Minnesota system, the former fifth overall selection has posted a .333/.391/.595 slash line with three doubles, two home runs and two stolen bases. During this noted stretch, Jenkins has posted five multi-hit efforts and only gone hitless three times. On the season, Jenkins has appeared in just 57 Triple-A contests (due to injury), but has posted a sharp .838 OPS with six home runs and 11 stolen bases. With the Twins competing for a Wild Card, expect them to turn to their top-ranked prospect in the near future to add another spark to the lineup, especially with Byron Buxton still on the shelf.

Boston Red Sox top-ranked prospect Franklin Arias has looked quite comfortable since joining Triple-A and is making a strong case to earn a call-up to the MLB roster down the stretch. Arias opened the 2026 season at the Double-A level, where he posted a dominant .318/.407/.587 line with an eye-catching .994 OPS. During this 75-game stretch, Arias launched 19 home runs while adding 17 doubles, with five stolen bases. Since moving up to Worcester, the shortstop has carried a .288/.356/.519 line with three doubles and three home runs over just 12 games. Given that Boston has lacked much production at shortstop with Trevor Story on the shelf, Arias remains in play not only to earn the call, but to have a sizable role.

According to Christina De Nicola of MLB.com, recently acquired first base prospect Jonathon Long could debut with the Miami Marlins later in the second half. De Nicola reports that Long, who was shipped to Miami ahead of the trade deadline, "should receive a callup by season's end if he continues to produce." Long joined the Marlins in the trade that sent left-handed pitcher Braxton Garrett to the North Side of Chicago. With Iowa this season, Long was very productive, posting a .283/.364/.455 line with a .819 OPS, 30 doubles, 12 home runs, and two stolen bases. Since joining Triple-A Jacksonville, Long has held a stellar .386 AVG through five games. With Miami struggling to hit southpaws, the right-handed power bat would provide a much-needed spark to their lineup.
