Three top fantasy baseball prospects - Kade Anderson, Ralphy Velazquez, Jaxon Wiggins - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.
Throughout the first half, prospects like Payton Tolle, Sam Antonacci, and Gage Jump have shown the importance of stashing prospects ahead of other promotions to the big leagues.
Below, we will look at three prospects who are putting themselves at the top of most stash rankings ahead of Week 15 of the fantasy season.

Kade Anderson, SP, Seattle Mariners
Current Level: AA
Availability: 5% rostered
2026 AA Stats: 72 2/3 IP, 1.36 ERA, 0.99 WHIP, 108 SO, 10 BB
Anderson continues to dominate in the minor leagues, and despite not having the clearest path to the majors, his upside is on another level compared to the names below him on this list.
Anderson joined the Mariners with the No. 3 overall pick in the 2025 MLB Draft out of LSU. The former College World Series MVP was not sent to a minor league affiliate following the draft, but would be given the green light to make his professional debut at the Double-A level to begin the 2026 campaign.
With Arkansas, the southpaw has looked more than comfortable and is not only on the verge of joining Triple-A but also potentially moving up to the big leagues.
Through his first 66 2/3 innings of work at the professional level, Anderson has posted a 1.22 ERA with a sparkling 0.71 WHIP. Across this stint, Anderson has racked up 99 strikeouts while showing near-perfect command, walking only 10 batters.
Over his 13 starts, Anderson has only allowed two or more runs in two games. Removing these two outings from his box score, Anderson would hold a 0.57 ERA across 62 2/3 innings with a 95:10 K:BB.
However, given Seattle's depth at the starting pitcher position, Anderson's debut will likely have to wait until later in the second half. Currently, the team has six capable MLB starters on the depth chart. This has prompted them to shift to a "piggyback" schedule to ensure that all six starters remain key pieces of the team's game plan and stay fresh for the remainder of their playoff push.
Even though the team has six starters, some of them have not had much success lately. Since June 1, Emerson Hancock has posted a 5.19 ERA over his last 26 innings while veteran Luis Castillo has held a 4.10 ERA over his last 48 1/3 innings of work.
While a debut is not imminent, if either Hancock or Castillo continues to struggle in relief, Anderson should be in strong contention to join the MLB bullpen as a long reliever. His innings will be capped, but when he does earn the call, he will hold value as an SP4/SP5 simply due to his elite strikeout upside and potential to boost your pitching ratios.
If your league has N/A spots, Anderson remains a priority stash.
Kade Anderson moves into 2nd place on the @MiLB strikeout leaderboard (99) following a 9-K outing for the Double-A @ARTravs 💎

Ralphy Velazquez, 1B, Cleveland Guardians
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 35 G, .269/.355/.403, 7 2B, 3 HR
First baseman Ralphy Velazquez is the Cleveland Guardians’ No. 2 prospect and is currently rolling through Triple-A.
Across 321 plate appearances this season, he has nine home runs while slashing .294/.386/.487, good for a 134 wRC+.
Even as his power continues to develop, he’s posted a .432 expected slugging percentage (xSLG) with an 11% barrel rate. Here's a breakdown of his Triple-A Statcast data.
The 21-year-old left-handed hitter from Huntington Beach, California, has displayed an advanced approach at the plate for his age, leading to a 23.6% strikeout rate and a 9.3% walk rate this season.
In a full season, he’s projected to hit around .260 with 25 home runs. However, his upside is limited, as he profiles as a strong-side platoon bat, similar to Kyle Manzardo.
Here is a breakdown of his splits this season in Triple-A.
Cleveland’s first basemen have combined to hit .209 with a 31.5% strikeout rate across 515 plate appearances, producing a 98 wRC+.
Right now, the Guardians have split time between Manzardo and Rhys Hoskins, with Manzardo playing mostly against right-handers and Hoskins handling the short side of the platoon against lefties.
With Cleveland just a game back of the division lead, there’s a clear argument for upgrading the position internally.
Given the organization’s limited spending habits and reluctance to add major contracts, promoting one of their top prospects makes sense.
From a fantasy standpoint, Velazquez is worth a stash in AL-only leagues and should be rostered in all 15-team mixed formats once he’s called up.
He likely won’t be an instant superstar, but his advanced approach and clear power upside can help fantasy teams down the stretch.

Jaxon Wiggins, SP, Chicago Cubs
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 8 IP, 5.63 ERA, 1.50 WHIP, 10 SO, 5 BB
Even though Wiggins is on the shelf, his path to the major leagues is one of the earliest among the names on this list.
Currently, the Cubs have a long list of injuries in both their starting rotation and bullpen, which will give Wiggins a clear path to the big leagues once he is cleared to return to Triple-A in the second half. Currently, the Cubs are without Edward Cabrera, Jameson Taillon, Cade Horton, Ben Brown and Justin Steele, leaving a clear path for their No. 3-ranked prospect.
During the 2025 season, Wiggins began the campaign in High-A but reached Triple-A late in the second half. With High-A and Double-A (68 1/3 innings), the right-hander posted a stellar 1.84 ERA, 0.94 WHIP, and a sharp 83:30 K:BB. However, during his first taste of action with Triple-A Iowa, Wiggins took a step back, allowing five runs over 9 2/3 innings.
In 2026, Wiggins made just two starts with Iowa before moving to the 7-day injured list with an elbow injury. While he was on the shelf for nearly two months, Wiggins has since begun a rehab assignment in the lower levels and was recently bumped up to High-A, where he has logged 6 1/3 innings with a 7:2 K:BB.
While he will not reach the majors until August, Wiggins has a path to becoming a high-impact option late in the season, given his clear path to MLB innings on a team that has its sights set on competing down the stretch. Those in formers with multiple IL spots should continue to keep a close eye on the Arkansas product.
Touted pitching prospect Jaxon Wiggins could be called up to help the Cubs later in the season, but he won't be ready in the near term as he continues his rehab work and buildup right now, @MLBBruceLevine told @mullyhaugh. pic.twitter.com/JZYdQFXIR5
