Three top fantasy baseball prospects - Quinn Mathews, Kade Anderson, Angel Genao - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.
Targeting prospects ahead of their eventual MLB debuts can not only save you some crucial FAAB dollars for the stretch run, but also provide your fantasy team with a lottery ticket.
In this piece, we will first take a look at two of the top prospects to stash in fantasy and also look at a surging hitter in the Cleveland system.

Quinn Mathews, SP, St. Louis Cardinals
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 92 IP, 3.13 ERA, 1.14 WHIP, 111 SO, 52 BB
You might remember Quinn Mathews as one of the quickest rising prospects of 2024, when he ascended from Low-A to Triple-A in his first year of professional baseball while posting a 2.76 ERA and 0.98 WHIP with 202 strikeouts and 49 walks in 143 ⅓ innings. He looked destined to reach the major leagues soon and make a big impact, before an injury-plagued season in 2025 completely tanked his value.
He missed time with a shoulder injury that held him out in early 2025, but what was more concerning was his performance after returning. The lefty saw a decrease in fastball velocity that fueled his breakout 2024 and struggled with mechanics, ultimately posting a 3.93 ERA and 1.55 WHIP. Not only did his strikeouts drop to 115 in 99 innings, but his control was nonexistent, with a whopping 16.8% walk rate that resulted in 74 free passes.
It's no surprise that Mathews entered 2026 as an afterthought for fantasy after the disastrous 2025, but he has done well to regain some of that form that made him a breakout star two seasons ago. He most recently displayed that upside in his last start on Friday, tossing seven shutout innings with 10 strikeouts against the Durham Bulls.
This wasn't just one good outing, either, as it marked his fourth straight quality start. In that span, the 25-year-old has posted a 1.04 ERA and 0.77 WHIP with 28 strikeouts and six walks in 26 innings.
For the season as a whole, his ERA now sits at 3.13, and his WHIP is 1.14. While it's not at the same level as his 35.4% strikeout rate in 2024, the youngster has punched batters out at a clip of 29.8% this season, which is a noticeable increase compared to last season.
Quinn Mathews recorded his first double-digit strikeout game since 2024 tonight.

The biggest thing he will need to keep in check is his walks, as his walk rate is still too high at 14.0%. However, that rate is inflated by poor play early on, as Mathews walked 16 batters in his first four starts of the year. He's gotten it more under control as of late during this recent hot stretch, but it's something to watch moving forward.
The Cardinals are far from having a dominant major league rotation, so it may not be long before they give the youngster a shot. Matthew Liberatore currently has a 5.18 ERA and 1.52 WHIP on the season, and St. Louis might be motivated to make a change if no improvements are being made.

Kade Anderson, SP, Seattle Mariners
Current Level: AA
Availability: 5% rostered
2026 AA Stats: 77 2/3 IP, 1.27 ERA, 0.64 WHIP, 115 SO, 10 BB
In similar fashion, I'm highly intrigued by the Seattle Mariners this trade deadline, and whether or not they're going to trade a starting pitcher for a bat. It sounds like Emerson Hancock and maybe Luis Castillo are the most likely trade candidates. But even if Seattle deals one of those two, there still won't be an open spot for Anderson.
However, trading Hancock might allow Anderson to come up and pitch in a piggyback situation, going 3-5 innings per outing. That might not be the most ideal situation for fantasy purposes as the opportunity for wins and quality starts would be severely limited, but it's better than Anderson not coming up at all.
Kade Anderson (@Mariners) was masterful again for the Double-A @ARTravs as he punched out 7 over 5 perfect innings.

As for the production, nothing has changed in that regard. Anderson is still dominating and having one of the best seasons by a pitching prospect that I've seen in my lifetime. In 77.2 Double-A innings, Anderson has a ridiculous 1.27 ERA, 0.64 WHIP, 3.6% walk rate, 41.7% strikeout rate, and a .151 BAA. You'll be hard-pressed to replicate those numbers on easy mode on MLB The Show with a perfect pitcher with maxed-out sliders.

Angel Genao, INF, Cleveland Guardians
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 66 G, .305/.391/.481, 16 2B, 8 HR, 6 SB
The hitter to keep an eye on in the coming weeks, especially in deeper formats, is Cleveland's Angel Genao. In 89 games this season between Double-A and Triple-A, Genao is slashing .296/.397/.464 with 11 home runs and eight steals. Eight of those 11 dingers have come in 65 Triple-A games, where he's slashing .305/.389/.483 with a 129 wRC+.
Genao brings an exciting blend of contact and approach, currently sporting a 14.3% walk rate, 15.6% strikeout rate, and an 82% contact rate. He's been hitting for more power this season as well, posting an 89.3 mph AVG EV and 44% hard-hit rate in Triple-A. It might not be the loudest profile around, but Genao could wind up as a Colt Emerson type of producer without the huge Emerson FAAB price tag.
I'm not sure exactly where Genao will fit in on the diamond once he gets the call, and there's no clear opening for him at the moment. But at least his ability to play three different infield positions will help his case.
