Top 25 Fantasy Baseball Prospects To Stash - Updated Rankings for 2023 Redraft (Week 21)

August 17, 2023

Eric's updated top 25 fantasy baseball prospects rankings for Week 21 (2023). MLB prospects, rookies, call-ups to make fantasy baseball impacts in redraft leagues.

We might only have 6-7 weeks left in the fantasy baseball season, but there's still plenty of time to improve your spot in the standings and make that championship or money push. Being ahead of the curve on some potential prospect promotions can certainly help you achieve those goals. If you have a bench spot you can use on a prospect stash, there are still plenty of intriguing prospects to consider that might be up by the end of the season.

And remember, it doesn't always have to be a stud prospect with a ton of helium. Just take Sal Frelick for example who was a good but not great prospect that has come up and provided solid fantasy value.

In this article, we will focus on MLB prospects, rookies, and call-ups who could make impacts for the 2023 fantasy baseball season. Stashing fantasy baseball prospects should be done strategically, not haphazardly. On top of discussing which prospects to stash or monitor, I'll also mention some prospects that I wouldn't be stashing to to either performance projection or the fact that I just don't believe they will debut this season. You need to be cognizant of which prospects will be up sooner and can make the biggest short-term impact on your teams – even if that means stashing a prospect that might be ranked lower than another in long-term dynasty prospect rankings.

Fantasy Baseball Prospect Rankings Analysis

Jordan Lawlar, Arizona Diamondbacks

Last week I mentioned that I didn't believe there was a high chance that Jordan Lawlar would be up with Arizona this season. Now I'm starting to think he might.

Lawlar was recently promoted to Triple-A after slashing .263/.366/.474 with 23 doubles, 15 home runs, and 33 steals in the Double-A Texas League. And if you look at his numbers since May 25, Lawlar slashed .316/.405/.551 with 10 home runs and 22 steals in 55 games.

Long-term, Lawlar's upside is a top-10 fantasy shortstop with the ability to exceed 20 home runs and 30 steals annually thanks to his above-average power and plus or better speed.

He'd be a highly coveted fantasy target if he gets the call, and I'm not ruling out a September callup similar to what Arizona did with Corbin Carroll last season. Do they really want to keep rolling with the uninspiring duo of Geraldo Perdomo and Nick Ahmed at shortstop as the fight for a wild car spot?

Joey Loperfido, Houston Astros

Another prospect recently promoted to Triple-A that everyone should have on their radar is Houston's Joey Loperfido. The former 7th round selection out of Duke has back to back productive seasons in the minors and is one of a handful of prospects to have more than 20 home runs and 20 steals so far this season.

In 92 games overall, Loperfido is slashing .293/.383/.546 with 22 doubles, 20 home runs, and 23 steals. His above-average power and speed blend would make him intriguing for fantasy purposes if Houston calls him up by the end of the season.

Pete Crow-Armstrong, Chicago Cubs

Well, Pete Crow-Armstrong has certainly hit the ground running in Triple-A. In 10 games at the level, Crow-Armstrong has slashed .275/.408/.575 with three doubles, three home runs, three steals, and eight walks.

Given his power/speed blend, Crow-Armstrong has the upside to make a significant fantasy impact once he's up. However, there's not a clear-cut opening for him with the Cubs right now, unless they want to bring him up to rotate with Mike Tauchman, Ian Happ, and Seiya Suzuki in the outfield and maybe even with Christopher Morel at DH. Three of those four are right-handed batters, so it makes sense.

Colton Cowser, Baltimore Orioles

After hitting just .115 with zero home runs and two extra-base hits total in 77 plate appearances, Colton Cowser finds himself back in Triple-A Norfolk. If you had or still have Cowser on your roster, he's an easy drop right now in redraft leagues.

I'm still a believer long-term, but I'm not sure he gets another shot this season due to this performance, and the next opening might go to Heston Kjerstad or someone else.

Trey Cabbage, Los Angeles Angels

I'm not suggesting you run out and stash Trey Cabbage right now, but he's certainly one to keep an eye on and could make an impact down the stretch if the Angels decide to give him another shot over the final six weeks of the season.

Cabbage is having a phenomenal season with Triple-A Salt Lake, amassing 26 home runs and 27 steals in 91 games with a .303/.370/.591 slash line. He's not going to be a stud and the strikeout rate is a tick above 30%, but there would definitely be some deep-league appeal here if he gets recalled.

Robert Gasser, Milwaukee Brewers

While he might not have the buzzy prospect name, Robert Gasser is a name to keep an eye on down the stretch. Over his last nine starts (45.1 IP), Gasser has a solid 2.98 ERA, 1.17 WHIP, 7.2% walk rate, and a 31.4% strikeout rate in Triple-A. He's probably the next man up if Milwaukee needs a starter.
