St. Louis Cardinals pitching prospect Quinn Mathews turned in another stellar effort at Triple-A on Friday evening and is on the verge of reaching the major leagues. Facing Triple-A Durham, the southpaw struck out an impressive 10 hitters over seven innings of three-hit ball. He walked only three batters and allowed one unearned run. Since May 28, the Stanford product has been among the most dominant pitchers at the top level in the minors and is making a strong case to join the Cardinals. During these noted 56 1/3 innings, the left-hander has posted a sharp 1.60 ERA with a 0.83 WHIP while holding a 67:22 K:BB. While there may not be a clear opening for the left-hander, his recent surge makes him a top prospect to stash among pitchers, as his debut could occur in early August.

Miami Marlins outfield prospect Cam Cannarella has yet to slow down since moving up to Triple-A Jacksonville and has put himself firmly on the stash radar in deeper redraft leagues. Cannarella earned the call to the team's top minor-league club last week and has continued to flash elite upside. Across six games with the Jumbo Shrimp, the young outfielder has held a .292/.393/.500 line with two doubles and a long ball. Cannarella began the season with High-A but has progressed through his system at a very impressive rate. Across 52 games shared between High-A and Double-A, the Clemon product held a .365/.443/.599 line with 12 round-trippers and nine stolen bases. His impressive play and quick transition to Triple-A have made him a worthy stash target in deeper 12+ team leagues as a late-season MLB debut is within reach.

Milwaukee Brewers infield prospect Andrew Fischer continued his impressive power surge on Friday evening as he launched his 30th long ball of the MiLB season against Double-A Chattanooga. While Fischer has endured a bit of a skid at the plate, his power has remained a key part of his game as he has gone deep twice over the last eight contests. The No. 8-ranked prospect in the system began the 2026 season at the High-A level, where he needed just 54 games to prove he was ready to join Double-A. With Wisconsin, Fischer hit 20 home runs with a sharp 1.118 OPS. Since moving to Double-A (29 games), Fischer has hit 10 home runs while holding a .253/.387/.636 line. While he will likely need to have a brief taste of Triple-A before being in serious contention to reach the majors, his elite power upside has kept the door open for a September call-up.

Los Angeles Angels starting pitching prospect George Klassen is emerging as a deep-league stash target. In his most recent outing for Salt Lake, the No. 4-ranked prospect in the system tallied a season-high 11 strikeouts over six innings of one-run ball. This was a nice bounce-back outing from Klassen as he allowed four runs in his previous start against Sacramento. The former sixth-round selection made his MLB debut earlier this season but stumbled, allowing six earned runs (seven total runs) over just 4 2/3 innings. Through 78 1/3 total innings at Triple-A, Klassen has carried a modest 4.25 ERA with a 1.47 WHIP. However, seeing him begin to turn the corner is a positive sign and suggests his second stint in the majors could be far more productive. For now, he is worth monitoring in deeper 12+ team formats.
