Three top fantasy baseball prospects - Hagen Smith, Jaxon Wiggins, Ralphy Velazquez - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.
Over the opening months of the 2026 season, managers have seen many prospects make a massive impact for fantasy, such as Parker Messick, Payton Tolle, Henry Bolte and Carson Benge.
Below, we will look at two emerging pitching prospects at the Triple-A level and a top stash for power upside.
Should fantasy managers stash these high-end prospects? Let's dive in!

Hagen Smith, SP, Chicago White Sox
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 53 IP, 4.75 ERA, 1.45 WHIP, 79 SO, 39 BB
Smith was selected by the White Sox with the fifth overall pick in the 2024 MLB Draft and ranks as MLB.com's No. 55 overall prospect. He spent his entire 2024 season at High-A and then spent all of 2025 at Double-A.
As expected, the left-hander was given the green light to begin 2026 in Triple-A, where he has shown some impressive "highs" but some concerning "lows." Through his first 22 1/3 innings, Smith posted a sharp 2.82 ERA while striking out 32 hitters. However, in this stint, he walked a rather high 16 hitters, which inflated his WHIP to 1.25.
Then, over his next three outings (11 2/3 innings), Smith allowed 10 earned runs with a 15:11 K:BB. However, the Arkansas product quickly bounced back, posting a strong 2.37 ERA with a much-improved 32:7 K:BB over his next 19 frames.

This career-best stretch was brought to a screeching halt on June 13 when he allowed a season-worst seven earned runs before being placed on the injured list with a shoulder impingement.
Smith returned to action over the weekend at Triple-A but logged only one frame in his return. Managers should continue to monitor his usage, as he may take a few outings to return to a starter's workload.
Once built up, he could quickly earn the call, as Chicago's back half of the starting rotation is not very impressive or deep, with Anthony Kay and Erick Fedde currently occupying those spots.

Ralphy Velazquez, 1B, Cleveland Guardians
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 43 G, .268/.362/.415, 10 2B, 4 HR, 40 SO, 19 BB
A lot of fantasy managers might not be familiar with Cleveland Guardians' top prospect Ralphy Velazquez. Velazquez was taken in the first round (23rd overall) of the 2023 MLB Draft. Although he slowly rose up Cleveland's Minor League ranks, the hard-swinging lefty slugger is knocking on the door of a promotion to the big league roster.
Velázquez really broke out during the 2025 season at both High-A and Double-A. He slashed a combined .265/.342/.497 with 22 home runs, 28 doubles, 85 RBI, 52 walks, and one stolen base in 122 games across those two levels. Those numbers made him a top-100 prospect on both Baseball America and MLB Pipeline before the 2026 campaign.
Velazquez got off to a nice start at Double-A to begin the year. He slashed .317/.414/.566 with seven home runs, nine doubles, three triples, 30 RBI, and 22 walks in his first 36 games with the Akron RubberDucks before being promoted to Triple-A Columbus in mid-May. While there was an adjustment period for him once he was promoted to Triple-A, he has settled in quietly since the beginning of June.

The Guardians' top prospect is batting .291 with four home runs, six doubles, 16 RBI, and 14 walks since June 2. His xwOBA (.349), expected batting average (.259), expected slugging (.445), average exit velocity (89 mph), and zone-swing rate (71.3%) all rank pretty well, and he's not striking out as much recently. Velázquez has only six strikeouts in 41 plate appearances in the month of July.
There is a chance the Guardians call up Velazquez sometime in August/September. He has been hitting the ball well over the last few weeks and has tallied a hit in seven of his last 10 contests. His power potential makes him a stash in some leagues at this point in the year. The lefty slugger has the tools to make an immediate impact in the big leagues.

Jaxon Wiggins, SP, Chicago Cubs
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 13 IP, 9.00 ERA, 1.92 WHIP, 17 SO, 13 BB
Usually, this article highlights the top-performing prospects and whether they are worth stashing in leagues. However, that hasn't been the case with Chicago Cubs top pitching prospect Jaxon Wiggins, who hasn't posted solid numbers since returning from injury. Still, he's a prospect fantasy managers should get familiar with because he could make an impact down the stretch.
It hasn't necessarily been a great year for Wiggins. He started the year with the Triple-A Iowa Cubs, where he looked good in his first start. The 24-year-old right-hander threw four innings of one-run ball with six strikeouts in his season debut against Triple-A Columbus on March 29.
After that solid outing, things have gone downhill for him. He struggled in his next Triple-A start on April 4 (four earned runs across four innings) and then went on the injured list due to right elbow inflammation on April 15. Wiggins proceeded to miss two months before appearing in his first rehab assignment outing on June 15 with the ACL Cubs at the rookie ball level.
He made three rehab starts as part of his ramp-up process (one at rookie ball, three at High-A) and was eventually activated from the injured list on July 10. The results, though, haven't been great for Wiggins since returning to Triple-A. He allowed three runs across 2 2/3 innings against Triple-A St. Paul on July 10 and gave up five runs across 2 1/3 innings against Triple-A Memphis on July 17.

Even though the Cubs' top pitching prospect has had his struggles in his first two starts back at Triple-A, he could still find his way to the big leagues in September. Fantasy managers have to remember that Wiggins missed multiple months with a right elbow injury. He is still trying to get into a rhythm on the mound following a multi-month absence.
Wiggins has the stuff to contribute to this Cubs team later this season. He has a solid 28% strikeout rate, 31.5% whiff rate, and a 14% swinging strike rate across 13 innings pitched at Triple-A in 2026. Despite the lack of results since returning, things could turn around for him in the coming weeks. If he gets into a groove, Chicago could call him up to provide a boost to either the rotation or the bullpen at some point.
Fantasy managers should only monitor him in leagues right now since he has struggled recently. However, if he puts together a couple of nice outings in a row, he could creep into must-stash territory in all leagues. The Cubs need the pitching help, and Wiggins would provide that.
