3 Impact Fantasy Baseball Prospects To Stash - Bubba Chandler, Zac Veen, Evan Carter

Joey analyzes three top fantasy baseball prospects - Bubba Chandler, Zac Veen, Evan Carter - who could make big impacts this season. These MLB prospects are potential waiver wire pick-ups or stashes.

At this point in the season, fantasy managers should stash at least one prospect on their fantasy team. These prospects could be a big boost in your fantasy lineups once they get to the majors. While we don't know when certain prospects will be called up, stashing high-end prospects could be a league-winning move.

In this article, we will look at three potential prospect stashes in pitcher Bubba Chandler, outfielder Zac Veen, and outfielder Evan Carter. Although Veen is currently in the majors, he should still be considered a stash following his rough start. All three players have shown their upside at some point in their minor league careers.

So, let's dive in and see if Chandler, Veen, or Carter should be stashed and grabbed off the waiver wire before it's too late. If you have any other questions about which prospects you should be stashing, be sure to check out all our content here at RotoBaller.

Bubba Chandler, SP, Pittsburgh Pirates

Current Level: Triple-A Indianapolis
Availability: 22% rostered
2025 AAA stats: 3 GS, 1.69 ERA, 18 K, 0.84 WHIP

Since being drafted in the third round of the 2021 MLB Draft, Chandler has surely shown his potential in the minors. Even though he struggled a bit with command at High-A during the 2023 season, the right-hander took his game to another level last year. He finished with a combined 3.08 ERA, 1.02 WHIP, and 148 strikeouts across 26 games (23 starts) at Double-A and Triple-A.

More importantly, Chandler was dominant in his seven starts at Triple-A to end the 2024 season. He allowed just eight runs across 39 1/3 innings pitched (1.83 ERA) to go with 54 strikeouts and a 1.04 WHIP. Opposing hitters also had only a .183 batting average against him across those seven appearances.

After that impressive showing, many thought the 22-year-old had a great chance to make Pittsburgh's Opening Day roster in 2025. While that wasn't the case for him, Chandler should be called up by the Pirates within the next few months. He continues to throw the ball well in Triple-A and has only allowed two runs across 10 2/3 innings (1.69 ERA) to begin the year.

That’s the hardest pitch thrown by a MLB or Triple-A starting pitcher this year, equalling Hunter Greene’s velo.

As a result, Chandler is someone fantasy managers should be looking to stash right now. His best start in Triple-A this season came back on April 8 when he struck out eight batters across four innings of one-hit ball. With an elite fastball and an above-average slider, MLB Pipeline's No. 14 overall prospect has the makings to be a top pitcher in the league one day.

That's why you should be picking up Chandler and stashing him on your bench right now. It's only a matter of time until the Pirates call him up, especially since the team sits at 6-12 on the season. The right-hander is one of the few prospects who can immediately make an impact in the major leagues and should not currently be available in your league.

Zac Veen, OF, Colorado Rockies

Current Level: Colorado Rockies
Availability: 12% rostered
2025 AAA stats: 8 G, .387/.472/.677, 1 HR, 8 RBI, 7 R, 1 SB
2025 MLB stats: 8 G, .107/.167/.310, 3 H, 1 2B, 1 RB, 11 K 

The Colorado Rockies officially called up their No. 8 prospect earlier last week, and many fantasy managers rushed to their waiver wire to pick him up. However, Veen has struggled in his first few plate appearances in the majors. He has just three hits in 28 at-bats to begin his MLB career (.107 batting average) with one double, one RBI, two walks, and 11 strikeouts.

There's no doubt it has not been a strong start to Veen's major league career. His metrics across the board all rank poorly, including average exit velocity (88.4 mph), launch angle sweet-spot rate (17.6 percent), and whiff rate (41.9 percent), and his rostership has dropped significantly in recent days. So, it makes sense why the Rockies outfielder might not be the perfect stash candidate right now.

Nonetheless, fantasy managers shouldn't completely give up on him just yet. Once he gets adjusted to major league pitching and gets on base more, his fantasy value will take off. With a 28.4 ft/sec sprint speed, he has the potential to be a strong source of steals for your fantasy team in the future.

It was only a few years ago that Veen stole 55 bases during the 2022 minor league season. Although he only had a .245 batting average with 12 home runs that season, it's hard to ignore his 55 stolen bases across 126 games. The 23-year-old also stole at least 21 bases in each of his four full minor league campaigns.

Zac Veen put up 11 HR and 21 SB with a 118 wRC+ in 270 PA in the minors last year.

Lots of power+speed upside here.

You don't need me to tell you this, but I'll say it:

Pick him up and see where this goes.

Point of this post was to highlight the SB ceiling.

So, if you are in need of some steals moving forward, then Veen is a solid stash candidate on your bench. He has the potential to steal over 20 bases in 2025. With a weekend series upcoming against the Washington Nationals at home, holding him through this series might be a smart move. Coors Field continues to be known as the most hitter-friendly ballpark in the majors.

Evan Carter, OF, Texas Rangers

Level: Triple-A Round Rock 
Availability: 9% rostered
2024 MLB stats: 45 G, .188/.272/.361, 5 HRs, 15 RBI, 23 R, 2 SB
2025 AAA stats: 9 G, .138/.342/.276, 1 HR, 2 RBI, 5 R

A lot of fantasy managers wanted shares of Carter last year following his strong end to the 2023 season. The lefty hit .306 with five home runs, four doubles, and 12 RBI across 23 regular season games with the Rangers before batting .300 (9-for-60) in 17 postseason games. As a result, he was a popular breakout candidate heading into 2024.

However, Carter turned out to be one of the bigger fantasy busts last season. He dealt with a back injury for most of the season and didn't appear in a game over the final four months. Even when he was healthy, he wasn't doing much offensively. The 22-year-old hit just .188 at the plate with five home runs, 15 RBI, and two stolen bases across his first 45 games.

Unfortunately, those struggles have continued for Carter into the 2025 season. He batted just .154 with one RBI across 15 spring training games and is off to a rough start at Triple-A Round Rock. The former top-5 prospect is slashing only .138/.342/.276 with one home run, two RBI, and three stolen bases across his first nine games with the Express.

Given how much Carter has struggled over the past year, he should not be stashed in most leagues. At this pace, the young outfielder will likely spend a lot of time in the minors this season until he figures things out offensively. Therefore, it's probably best to stash another prospect. Both Chandler and Veen are better prospects to stash at this point in the year.

There really isn't a ton of hope surrounding Carter right now, and it remains to be seen if he can return to that 2023 form. Although the potential is there for him to be a solid MLB player one day, the 22-year-old isn't worth a stash in fantasy right now. Just keep an eye on him over the next few months.
