Luis Lara, OF, Milwaukee Brewers
Milwaukee Brewers outfield prospect Luis Lara is doing everything he can at Triple-A Nashville to encourage a promotion to the major leagues. The outfielder is hitting .313 with 56 runs, seven homers, 30 RBI, and 20 stolen bases across 67 games of action. That power-speed combination should play at the big league level (.873 OPS in 246 at-bats).
The Brewers have shown an ability to get the most out of all types of players in Milwaukee, and Lara profiles as another player who could thrive at American Family Field. With the Brewers beckoning, Lara is a name to target in the waiver-wire process, and he could provide immediate dividends for fantasy managers. Additionally, earlier in June, the Brewers inked the top-100 prospect to a seven-year contract extension, signaling his long-term role on this roster.
Entering Week 13, Lara profiles as a top outfield prospect to stash as he is on the trajectory to compete for an MLB debut in the coming weeks.

Jaxon Wiggins, SP, Chicago Cubs
Chicago Cubs right-handed pitching prospect Jaxon Wiggins is currently on a rehab assignment at High-A South Bend, where he pitched 2 2/3 innings, allowing one run with three strikeouts in a start on Sunday. It's been an injury-plagued year for Wiggins, the second-round pick out of the University of Arkansas, but the promising right-hander was part of the Futures Game last season as a representative of the Chicago Cubs organization.
Wiggins pitched to a 2.19 ERA between three levels in 2025, capped off by a finale at Triple-A Iowa. Across 78 innings, he totaled 97 punchouts with a stellar 1.03 WHIP. Recovering from right elbow inflammation, Wiggins is a promising prospect, and savvy fantasy managers should continue to keep an eye on his progress as he rehabs. Given Chicago's lack of starting pitching depth, Wiggins could become a priority pitching prospect to stash in the coming weeks once he returns to Triple-A.

Joshua Baez, OF, St. Louis Cardinals
St. Louis Cardinals outfielder Joshua Baez is getting very close to arriving in the majors, according to MLB Network's Jim Bowden, and he could be a huge source of power from the waiver wire in all formats. The 22-year-old is hitting .274 in his 67 games in Triple-A with 25 home runs, 64 RBI, and a .407 wOBA. Baez has also added 12 stolen bases and shown off five-tool ability, which gives him huge breakout potential. MLB Pipeline ranked Baez as the No. 64 prospect in baseball and the No. 3 prospect in the Cardinals' farm system.
The Cardinals have an exciting young lineup coming together, and Baez could be the next big piece to arrive. Since his call-up seems imminent, you can stash the slugger now in deep formats with plenty of bench room and be ready to grab him as soon as he's called up in standard-sized mixed leagues.

Deyvison De Los Santos, 1B, Miami Marlins
Miami Marlins first base prospect Deyvison De Los Santos stayed hot on Sunday, going 3-for-5 and extending his current hit streak to seven games, during which time he's gone 13-for-29 (.448) with three doubles, two home runs, and a pair of stolen bases. The latest hot stretch has pushed his season-long slash line to .273/.325/.445 with eight home runs and 11 steals. Last year at Triple-A, the powerful slugger recorded a 22.4 percent strikeout rate, but has lowered that to 18.8 percent in 2026, which should help make his case for a return to the majors.
The 6-foot-1 Dominican made a brief three-game debut with the Marlins at the beginning of this season, going 2-for-7 with three strikeouts during his time there. The 23-year-old blasted 40 home runs in 2024, and though his power took a step back last year (12 home runs), he's still got an average exit velocity of 90.1 mph and a max EV this year of 113.1 mph (93rd percentile), so he's still hitting it hard.
The right-handed hitter could get the call to the majors again soon, and with his home run upside and improved strikeout rate, along with the potential to add some steals, he makes for a solid stash option in deeper leagues.

Charlie Condon, OF, Colorado Rockies
Colorado Rockies outfield prospect Charlie Condon has enjoyed a power surge in the month of June and is on the verge of earning a call to the big leagues. Over the last 12 contests, the former Georgia standout has posted a dominant .318/.444/.818 line with an eye-catching six round-trippers, two doubles, and a solid 10:7 K:BB. Overall, Condon has done more than hold his own during his first taste of Triple-A action, carrying a .262/.397/.512 line with a .909 OPS across 64 games. During this stretch, Condon has launched 14 total home runs while holding a 70:46 K:BB.
Last summer, the former third overall pick split his time between High-A and Double-A. With Colorado dealing with many injuries in their outfield, Condon has a clear path to at-bats, and his current power surge is only bolstering his fantasy stock. Those needing power should view him as a priority stash.

Max Clark, OF, Detroit Tigers
Detroit Tigers outfield prospect Max Clark has continued to tap into his raw power in June at Triple-A and is seeing his stash value climb. Since June 1, Clark has carried a strong .270/.370/.476 slash line with one double, four home runs, two stolen bases, and a strong 11:10 K:BB. Prior to this recent surge at the dish, Clark held a lower .262 AVG with just two total round-trippers over his first 50 games of the regular season.
Last summer, Clark, the team's top-ranked prospect, split his time at High-A and Double-A, with most of his bats coming at High-A West Michigan. Through 111 games, he went deep 14 times and swiped 10 bags while holding a .271 AVG. Even though the Detroit outfield does not have a clear opening, his five-category skill set and rising power make him a top stash target in five-outfielder leagues. If he maintains this pace, he should contend for a July debut.

Franklin Arias, INF, Boston Red Sox
Boston Red Sox shortstop prospect Franklin Arias broke out of his mini-slump over the weekend, going 6-for-10 with a pair of three-hit games, which included three doubles and his first home run since June 2, a period of 14 games without one. The surge boosted his season-long slash line to .315/.395/.579 with 14 home runs and five stolen bases at Double-A Portland.
Also notable was the fact that for the first time all season, the 5-foot-11 Venezuelan made a start at a position other than shortstop, manning second base for the Sea Dogs in Saturday's contest. Although he's played some second base in the past, it is something to keep an eye on, as more starts there could provide added versatility and create another pathway to Triple-A and eventually the majors, perhaps even in 2026.
With Boston promoting Anthony Seigler from Triple-A to play second base with Isiah Kiner-Falefa (forearm) hitting the injured list, a promotion to Triple-A for Arias could be forthcoming. Once on the doorstep to the majors, Arias could become a stash option in deeper leagues.
