Andy's fantasy baseball prospects sleepers and risers to know for Week 6 of 2025. He analyzes top MLB prospects and rookies to stash based on recent performances.
Welcome Rotoballers to another edition of my biweekly prospect series. In this edition, we will analyze three rising prospects at the Triple-A level and determine if they are "must-stash" options. In our last edition, we looked at Baltimore's Coby Mayo, who has continued to swing a hot bat at Norfolk, and Tampa Bay southpaw Ian Seymour, who is enjoying a strong start to the campaign.
After a month of data, it is time to check in on several top prospects and see how they are performing in the minor leagues. Several top prospects have already begun to enjoy a strong start to the season. However, it is crucial to determine whether these performances truly matter in redraft leagues for 2025. Knowing which prospects to watch can put you ahead of your league mates and in the driver's seat.
Adding the right prospect can fill the missing piece on your roster and set you up for a fantasy championship. This week, we will look at two familiar names if you followed this column last season, and another budding ace in the Tampa Bay pitching factory. This fantasy baseball prospects biweekly series will examine a few key players in the minor leagues and assess whether they have a path to fantasy stardom in 2025.

Jordan Lawlar, INF, Arizona Diamondbacks
Diamondbacks No. 1 Prospect, Overall 10
Jordan Lawlar might be the hottest hitter in all of baseball. The top prospect in the desert is currently riding an 11-game hitting streak. During this impressive stretch, the infielder has held a .511/.582/.936 slash line with seven doubles, two triples, three home runs, and eight stolen bases. During this stretch, Lawlar tallied 18 RBI, scored 18 runs, and held a 7:8 K:BB.
Before this hot streak, Lawlar was still productive as he posted a .288/.390/.515 line with six doubles and three home runs across the first 17 games of the Triple-A regular season.
Lawlar made his MLB debut during the stretch run of the 2023 campaign and played a role in Arizona's World Series run. However, leading up to the 2024 season, the infielder was unable to break camp with the big leagues. He then underwent surgery on a torn ligament in his thumb and eventually suffered a Grade 1 left hamstring, which limited him to just 23 games in the minor leagues.
However, the former sixth overall pick is once again flashing his elite upside and making a strong case for returning to the big leagues.
Does this production matter? Unfortunately for Lawlar, he had a great opportunity to earn another taste of the majors with second baseman Ketel Marte (hamstring) hitting the injured list. However, weeks passed, and Tim Tawa was given the promotion. With Marte expected to return in the coming days, Lawlar may have to wait another few weeks for his call.
While it may be frustrating to see Lawlar produce at an elite level but not get the call, fantasy managers in standard 12-team formats should continue to stash Lawlar on their bench. Outside of Boston's Roman Anthony, Lawlar is the definition of a high-upside stash option.
Jordan Lawlar (@Dbacks' No. 1 prospect) delivers a four-hit performance for the Triple-A @Aces, his ninth multihit outing over his past 11 games.

Verdict: Stash in 12-team leagues
Cade Horton, SP, Chicago Cubs
Cubs No. 2 Prospect, Overall 49
Similar to Lawlar, injuries limited Cade Horton's 2024 campaign, but the budding ace appears to be putting those concerns behind him. In 2024, Horton began the season on a high note as he tossed 16 1/3 innings to the tune of a 1.10 ERA and a 0.92 WHIP at Double-A. During this stint, Horton struck out 18 batters and served up just two walks.
He was then given the call to Triple-A, where Horton took a step back as he allowed 15 runs across 18 innings. He was not given much time to work out these struggles as he was shut down in May due to a shoulder strain. He was on track to potentially return in August but faced a setback.
However, Horton progressed well in camp and was cleared to open the 2025 season with Triple-A. During his second stint at Triple-A, the former seventh overall pick has already shown significant improvements.
Through 23 innings of work, the right-hander has held an impressive 1.17 ERA with a 0.96 WHIP. He has tallied 28 total punchouts and allowed 12 walks. However, Horton's control seems to be improving in each start, as he has only served up two walks in his last two games, a stark contrast to the 10 he served up over his first three starts.
Looking under the hood, the budding ace has generated groundballs at a 32.6 percent rate and flyballs at a 43.5 percent rate, which is a strong improvement compared to the 23.4 percent rate and 53.2 percent rate, respectively, he generated at Triple-A last summer over a similar sample size.
Fantasy managers should continue to monitor Horton's progression as he could push for an MLB debut sooner rather than later. His most recent outing marked the first time this season he logged six innings in a given start.
With Justin Steele (elbow) sidelined for the remainder of the season, the Cubs will need additional reinforcements in their rotation, and their top pitching prospect fits the bill.
Cade Horton has pitched very well to open the season.
Tuesday: 6 IP, 3 H, ER, BB, 5 K
Season: 5 GS, 23 IP, 1.17 ERA, 0.96 WHIP, 14% BB, 32.6% KWalk rate is high overall, but has only two walks in his last two starts combined (10.2 IP).#BeHereForIt pic.twitter.com/yNjSxaVMEN

Verdict: Stash in 15-team formats
Jacob Misiorowski, SP, Milwaukee Brewers
Brewers No. 4 Prospect, Overall 97
Milwaukee's Jacob Misiorowski will round out this piece. While Milwaukee already turned to their pipeline to fill a rotation spot earlier this season, Misiorowski was not given the call. Instead, the Brewers promoted Logan Henderson to make a spot start.
However, fantasy managers should be keeping a close eye on the No. 97-ranked prospect in the sport on the MLB Pipeline.
Last summer, Misiorowski spent most of his time at Double-A, logging a 3.50 ERA with a 1.28 WHIP across 79 2/3 innings. He was then given a brief taste of Triple-A, where he posted a 2.55 ERA with a 0.85 WHIP. However, during this stint, he was deployed primarily out of the bullpen.
This season, Misiorowski opened the campaign with Triple-A Nashville and has only returned to the bullpen once, suggesting that the team views him primarily as a starting pitcher.
Across his first 29 2/3 innings of the 2025 campaign, Misiorowski has held an impressive 1.82 ERA with a 0.91 WHIP. During this stint, he has struck out 38 batters and served up 13 walks.
However, similar to Horton, Misiorowski has seen his control improve drastically over the last few weeks. After serving up 12 walks over his first 18 2/3 innings of the campaign, the former second-round pick has held a near-perfect 17:1 K:BB over his last 11 frames.
While the Brewers recently welcomed back Tobias Myers from the injured list, Misiorowski would provide them much-needed depth to their rotation. Currently, Quinn Priester and Chad Patrick hold the No. 4 and No. 5 spots in the rotation. Priester enjoyed a strong start to his tenure in Milwaukee but has posted a 7.00 ERA and a 2.11 WHIP over his last two starts.
Patrick has allowed two runs in each of his past two starts and held a modest 1.26 WHIP during this stretch.
If Misiorowski continues to dominate at Triple-A, expect the Brewers to give him the call.
Can we all appreciate the absurdity of this? Misiorowski has randomly found a changeup that grades out as plus plus from @TJStats stuff model (using his two outings this week) on top of a 93 mph slider and two other 70 grade offerings.
He also walked just one in 13 innings 🥵 pic.twitter.com/RBCTgD8RMK— Jake McKibbin (@thebrewerblogs) April 28, 2025
