Fantasy Baseball Prospects to Stash: Week 18 (2026)

Fantasy Baseball Prospects to Stash: Week 18 (2026)

The calendar is about to turn to August, and that means organizations are beginning to make some difficult decisions. Contenders are searching for immediate upgrades, while rebuilding clubs are preparing to evaluate their next wave of young talent. With every passing week, another top prospect inches closer to forcing his way onto a major league roster.
This week’s stash list features several familiar names, but their performances continue to evolve. A few hitters are heating up at exactly the right time, while multiple pitching prospects may have delivered their strongest outings of the season. If you’re looking to make one final stash before the fantasy baseball playoffs arrive, now is the time to act.

Fantasy Baseball Prospects to Stash

Here are this week’s top prospect stashes.

Charlie Condon (1B, OF – COL) | Top 100 Prospect Ranking: 75

Current Level: Triple‑A
ETA: August

Condon continues to knock on the door despite still waiting for his first Triple-A home run in recent weeks. He collected six hits over the past week, consistently finding ways to reach base even though the power hasn’t fully returned after the All-Star Break.
I’m not overly concerned about the lack of home runs. The quality of his at bats has remained strong, and Colorado has every reason to give one of its premier offensive prospects an opportunity before long. Once the power begins to return, it could come in bunches, especially with half of his games eventually being played at Coors Field. He remains one of the highest upside hitting stashes in fantasy.

Joshua Baez (OF – STL) | Top 100 Prospect Ranking: 65

Current Level: Triple‑A
ETA: August

Baez is beginning to heat up at the perfect time. He collected seven hits over the past week, including two home runs, reminding fantasy managers why his raw power ranks among the best in the Cardinals organization.
The strikeouts will always be part of his profile, but few prospects on this list possess Baez’s combination of power and athleticism. He has already surpassed the 30-home run mark in the minors this season while continuing to flash his double digit stolen base ability with 15 steals. Furthermore, if St. Louis is searching for another impact bat during the stretch run, Baez has positioned himself squarely in the conversation.

Kade Anderson (SP – SEA) | Top 100 Prospect Ranking: 6

Current Level: Triple‑A
ETA: August

After an extended break following the Futures Game, Anderson looked every bit like an ace in his return.
His first start since July 3 couldn’t have gone much better, as he fired five perfect innings with seven strikeouts.
Seattle continues to manage his workload carefully, but every outing reinforces why he’s viewed as one of baseball’s elite pitching prospects. His combination of swing and miss stuff and advanced command gives him legitimate fantasy ace upside whenever the Mariners decide the time is right. Additionally, rumors continue to swirl that Emerson Hancock and/or Luis Castillo could be moved before the trade deadline. If that happens, Anderson could be next in line for a promotion.

Max Clark (OF – DET) | Top 100 Prospect Ranking: 7

Current Level: Triple‑A
ETA: August

Clark may have had the most impressive offensive week of anyone on this list.
He piled up 10 hits, launched two home runs, stole a base, and finished with five walks and five strikeouts; an encouraging sign that his plate discipline remains intact.
What makes Clark such an exciting fantasy stash is his ability to contribute across the board. He offers power, speed, on-base ability, and premium athleticism, giving him true five-category upside. Moreover, advanced metrics continue to support his breakout, as he ranks among baseball’s top prospects in quality of contact.

Walker Jenkins (OF – MIN) | Top 100 Prospect Ranking: 11

Current Level: Triple‑A
ETA: August

Jenkins continues to prove why many evaluators consider him one of the safest offensive prospects in baseball.
He recorded six hits, including two doubles and a stolen base, while finishing the week with three walks and just three strikeouts.
His balanced approach continues to stand out. Jenkins rarely expands the strike zone, consistently hits the ball with authority, and contributes in nearly every fantasy category. Meanwhile, Minnesota remains firmly in the playoff picture, and Jenkins could eventually provide the offensive spark the Twins need down the stretch.

George Klassen (SP – LAA) | Top 100 Prospect Ranking: Unranked

Current Level: Triple‑A
ETA: August

Klassen makes his debut on this week’s stash list after quietly putting together one of the best stretches of his professional career.
His brief Major League stint in April was forgettable, as he walked 10 batters in just 4.2 innings while posting an 11.57 ERA.
His Triple-A season has been a mixed bag because of command issues, resulting in a 4.13 ERA and a 1.44 WHIP across 18 starts. However, there are encouraging signs that things may finally be clicking. In his most recent outing, Klassen threw more than six innings without issuing a walk while striking out seven. Before that, he punched out 11 hitters over six innings.
If he’s beginning to harness his elite stuff, the Angels may be willing to give him another opportunity sooner rather than later.

Additional Fantasy Baseball Prospects to Consider

Nelson Rada (OF – LAA) | Top 100 Prospect Ranking: Unranked

Current Level: Triple‑A
ETA: August

Rada continues to be one of the most underrated fantasy prospects in baseball.
He finished the week with 10 hits, three doubles, and two stolen bases, once again showcasing the elite bat to ball skills that have defined his season.
Speed remains his calling card, but his improving quality of contact has been equally encouraging. Few prospects combine his ability to reach base with disruptive speed, making him an ideal category contributor once he reaches the majors.

Angel Genao (SS – CLE) | Top 100 Prospect Ranking: 41

Current Level: Triple‑A
ETA: August

Genao simply continues to hit.
This week, he produced nine hits, one home run, and eight RBI, continuing one of the most consistent offensive seasons among middle infield prospects.
The switch hitting infielder has developed one of the better offensive profiles in Triple-A, pairing excellent contact skills with impressive strike-zone judgment. Although a clear path to everyday playing time isn’t available at the moment, keep an eye on Cleveland’s middle infield. An injury or a prolonged slump from Bryan Rocchio could quickly create an opportunity.

Kaelen Culpepper (SS – MIN) | Top 100 Prospect Ranking: 29

Current Level: Triple‑A
ETA: August/September

Culpepper returned from the injured list this week, making this more of a “keep an eye on him” recommendation than an immediate stash.
In four games, he collected two hits, including a double and a stolen base.
The Twins will likely ease him back into everyday action, but his athleticism and offensive upside remain extremely intriguing. If he gets hot over the next couple of weeks, Minnesota could view him as a potential contributor during its playoff push.

Quinn Mathews (SP – STL) | Top 100 Prospect Ranking: Unranked

Current Level: Triple‑A
ETA: August

Mathews continues to make a compelling case that he’s ready for the next challenge.
His latest outing featured seven innings, 10 strikeouts, and three walks. Although the command wasn’t quite as sharp as it had been in previous starts, his ability to miss bats remains outstanding.
Few pitching prospects have been as consistently dominant during the second half, and the Cardinals may soon need another rotation option. If an opportunity opens following the trade deadline, Mathews appears ready to answer the call.
