Four top fantasy baseball prospects - Robby Snelling, Jesus Rodriguez, Max Clark, Joe Mack - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.
Welcome to Week 6 and RotoBaller's Redraft Fantasy Baseball Prospects Report for the 2026 MLB season, looking at prospect risers and fallers in redraft fantasy baseball leagues.
As we advance deeper into the regular season, we'll take a closer look at Robby Snelling, Jesus Rodriguez, Max Clark, and Joe Mack. Each is a top talent in their team's farm system who has either already debuted early this season or is knocking on the door of receiving a call to the show.
We’ll dive into their early performances, analyze what’s working (and what’s not), and offer insights on what fantasy baseball managers can expect as we get deeper into the 2026 season.

Robby Snelling, SP, Miami Marlins
Availability: 16% rostered
2026 Triple-A Stats: 6 GS, 29.0 IP, 1.86 ERA, 2.64 xFIP, 13.66 K/9, 4.66 BB/9, 0.62 HR/9, 56.9% GB%, .184 BABIP
The Padres selected Snelling with the 39th overall pick in the 2022 MLB Draft, but he was traded to Miami at the 2024 trade deadline. He developed into a top pitching prospect with the Marlins, and now, he's scheduled to make his MLB debut on Friday.
The southpaw's development was fueled by an increase in velocity prior to the 2025 season. He got the fastball up to the mid-90s, and he also perfected a changeup with impressive depth and a 47.6% whiff rate. He rounds out his repertoire with a sharp slider and a curveball with a profound shape.
Snelling has done a really good job getting whiffs — and strikeouts, in particular. He's getting barreled at an 11.8% rate, but he continues to miss bats quite often. This bodes well for his upside as a high-strikeout option in fantasy baseball.
There's a little risk associated with adding Snelling in redraft leagues, mostly because he hasn't even pitched in an MLB game yet. With that said, his velocity and ability to pitch deep into games allow him to accumulate fantasy points.
"Robby Snelling is carving!"

Jesus Rodriguez, C/OF, San Francisco Giants
Availability: 2% rostered
2026 MLB Stats: 4-for-9, 1 HR, 1 RBI, 1 R, 0 SB, 0.0% BB%, 0.0% K%, 246 wRC+
Rodriguez signed with the Yankees out of Venezuela all the way back in 2018, and he was traded to the Giants in exchange for Camilo Doval at the 2025 trade deadline. He has emerged as a bat-first prospect with the ability to catch or play the outfield.
Rodriguez's progression through the minors has been slow and steady, and the Giants (plus fantasy managers) are now being rewarded for their patience.
Defensively, Rodriguez is still a work in progress behind the plate. He logged 16 games at catcher in Triple-A this year, and the Giants have used him at both catcher and right field since calling him up. The jury is still out on his throwing arm, as he's 0-for-3 retiring base stealers so far in the majors.
At the plate, he's an advanced hitter with top-tier bat-to-ball skills. His 16.5% whiff rate at Triple-A ranked in the 92nd percentile, and his 9.6% strikeout rate was in the 96th. We're impressed by his 75.58% zone swing rate, but a 31.4% chase rate suggests that he might swing a little too much overall.
With that said, his discipline looked very solid at Triple-A, where he walked (10.4%) more than he struck out (9.6%).
While Rodriguez has a plus hit tool with the ability to spray the baseball to all parts of the field, there's not a ton of power or loud contact. He has never hit more than 10 homers in a single minor league season, and his average exit velocity in Triple-A was only 85.5%.
Rodriguez is now 4-for-9 with a home run since being called up to the majors. The power is a pleasant development, but we're certainly not surprised by his overall ability to rack up hits and get on base. He has the potential to be a valuable midseason addition in redraft leagues at the catcher position.

Max Clark, OF, Detroit Tigers
Availability: 6% rostered
2026 Triple-A Stats: 31 G, .276/.355/.390, 1 HR, 12 RBI, 18 R, 9 SB, 11.3% BB%, 14.9% K%, 102 wRC+
Clark was the No. 3 pick in the 2023 MLB Draft, signing for just shy of $7.7 million. He was drafted straight out of high school, and he has progressed through the minors rather quickly for a former prep prospect.
Clark showcases an advanced hit tool that would suggest he's ready to face major league pitching. He tracks the ball nicely coming into the place, and he has the quick hands and bat speed necessary to make consistent and loud contact. While not a major power threat, Clark's 103.7 mph EV90 at Triple-A is certainly encouraging.
The outfield prospect has a mere 41.3% swing rate, so it's possible that he could benefit from being more aggressive. The swing decisions look good, though, as evidenced by a 21.8% chase rate (78th percentile) and 15.1% whiff rate (94th percentile).
He also possesses game-changing speed, which serves him well in the field and on the basepaths. Defensively, Clark has a long-term home in center field, where his range and glove work are on display often. On the basepaths, he's a potential threat to steal 30 bases in any given season.
Although there's not much power in his makeup, Clark's pure on-base skills and his speed offer plenty of upside in fantasy baseball. If he can hit at or above a league-average clip while pushing for 30 steals, he'll be an incredibly valuable fantasy option. Although he's cooled off a little at Triple-A lately, he's still worth stashing in most redraft leagues ahead of his anticipated MLB debut this season.

Joe Mack, C, Miami Marlins
Mack was the No. 31 overall pick in the 2021 MLB Draft. Selecting a prep catcher can be risky, but Mack checked several boxes for the Marlins and ultimately landed a $2.5 million signing bonus.
Mack's development and progression through the minors have required some patience, as we're nearly five years removed from his draft date. We do expect prep prospects to take a little longer, though, and Mack is still on the young side at just 23 years old.
A defense-first catcher, Mack projects as someone who will slot into the bottom third of the lineup. There's a little bit of power upside, but the hit tool is below-average, and we expect him to endure some adversity against MLB-caliber pitching. He had a 61.6% zone swing rate and 29.3% whiff rate in Triple-A, both of which rank in the 40th percentile or lower.
Mack excels at stealing strikes and throwing out baserunners, routinely putting his receiving skills and arm strength on display. This won't have a major impact on his fantasy value, but the defensive success should help him get into the lineup on a more consistent basis.
Managers who roster Mack are invested in his power upside, though. The whiffs are a concern, but we're encouraged by his 104.8 mph EV90 and his 21 homers in the minors last year. He easily has the potential to slug another 20+ home runs in any given MLB season once he settles in and adapts to the next level of pitching.
Mack ranks as the #24 overall prospect and the #1 catcher prospect in RotoBaller expert Eric Cross' 2026 fantasy baseball redraft rankings. Managers in deeper leagues should consider stashing him as a low-risk catcher who could work his way into your fantasy lineup if he taps into more power.
