Roman Anthony, OF, Boston Red Sox
Ok- Triston Casas (knee) is out for the rest of the season. Surely, the Red Sox do not plan to play Romy Gonzalez and Abraham Toro at first base for any extended period of time, right? RIGHT?
Although the Red Sox front office has insisted that they don't plan on moving Roman Anthony or any of their other outfielders to first base to get them all into the lineup, something will surely have to give soon with Casas out of the lineup. A team with playoff aspirations can't keep elite hitting prospects in the minors and play journeymen at first base every day.
Anthony should be a familiar name to most fantasy baseball players. The arguable top prospect in baseball continues to hit well at Triple-A, as he has throughout his minor league career.
He has a 147 WRC+ while having both strong plate discipline and quality of contact metrics.
Roman Anthony hasn't hit a barrel this week, but that doesn't mean he isn't improving. His Whiff% has steadily decreased throughout the season as he is battling deeper into counts. He is such an amazing talent! pic.twitter.com/p3FWhBt2C7

I've been clamoring for Anthony to play in Boston for weeks, so it's anyone's guess when the Red Sox will finally call him up. When he gets the call, he'll be a solid starting outfield option in all formats.
Matt Shaw, 3B, Chicago Cubs
Matt Shaw has not exactly set the world on fire so far in Triple-A after he was demoted back to the minors. He has a 107 WRC+ and only one homer. However, he has a very promising 17.4% BB-rate and only a 11.6% K-rate.
Shaw will need to start hitting the ball better to get a call back to the majors, but his excellent plate discipline metrics show that he's not pressing despite the poor start to his campaign.
Unlike many other prospects to stash, Shaw's pathway is pretty clear whenever he gets on a bit of a hot streak, and the Cubs are ready for him to return. The Cubs were planning on Shaw being their third baseman of the future all offseason, and that plan isn't likely to deviate due to a disappointing debut.
Jon Berti is a quality bench piece, but he is unlikely to be an everyday player for long on this team with strong aspirations this season.
It's not out of the ordinary for a top prospect to struggle in his first taste of the majors, get demoted, and come back with a vengeance. I expect Shaw to do much of that when he returns to Chicago.
When Shaw gets the call, he will have five-category upside in a loaded Cubs lineup. He could be a back-end starting third baseman or a solid corner infield option.
Jac Caglianone, 1B/OF, Kansas City Royals
When Jeff Passan tweets about what a prospect is doing, you know they're doing something special.
Jac Caglianone’s power is special. Now hitting .330 with a 1.012 OPS at Double-A. The Royals are trying to be cautious, but at some point — sooner than later — he’s going to be a solution for their outfield, which is collectively hitting .226/.282/.325. pic.twitter.com/XsYx02q28L

This whole offseason, I was pretty skeptical about whether we'd even see Cags in the majors this season. Although he got a ton of buzz after an incredible college career at Florida, his professional debut was quite lackluster. He had a 98 WRC+ across 126 PA in High-A.
Since spring training, Caglianone has been on a hitting rampage and is looking to bang the door down to the majors this season. In 23 PA this spring, he had a 331 WRC+, and he's followed that up by dominating Double-A. He has a 174 WRC+ with eight HRs.
While Vinnie Pasquantino has first base manned in Kansas City for the time being, the Royals are giving Caglianone more time in the outfield in an effort to get his bat into their lineup.
Despite their recent hot streak, the Royals are still in the bottom third of the league in nearly every offensive category, so they desperately need his infusion of power if they really want to reach the playoffs.
Caglianone is the only player in Double-A in this article, and it's unclear whether the Royals would be willing to call him up directly from Double-A or if they'd want to see him in Triple-A. If he gets the call to Triple-A, it should be red alert that a call to the majors could be imminent.
Caglianone makes some of the loudest contact in all of baseball and is an excellent stash for any team looking for power.
Jordan Lawlar, SS, Arizona Diamondbacks
So Jordan Lawlar's removal from the Aces lineup before last week's article was a false alarm, and that's a bummer.
He is coming off a bit of a down week, but still has six HRs, 12 steals, and a 153 WRC+ so far this season in Triple-A. Considering he's had stints in three seasons at the Triple-A level with an over 140 WRC+, he has very little left to prove in the minors and is just biding his time waiting for an opportunity to arise in the Diamondbacks lineup.
You't can't run from the Law 😤
Jordan Lawlar has been named the PCL Player of the Month by @MiLB after he hit .408/.487/.749 and led the PCL in runs scored (31), hits (42), total bases (77), extra base hits (21), OPS (1.235) and slugging percentage in April 🔥 @Dbacks |… pic.twitter.com/AIfj3qltnO

As the weeks pass, it seems more likely that Lawlar will need an injury to be called back to the majors.
There are very few prospects on the precipice of the majors with the fantasy upside Lawlar has, so he's worth stashing in most formats despite the lack of imminent opportunity in their lineup. When he gets the call, he should have five-category upside and could be a starting-caliber shortstop for fantasy rosters.
Marcelo Mayer, SS, Boston Red Sox
I've been trying to wait until Anthony gets the call to the majors before including Marcelo Mayer in the write-up portion of the prospects to stash, since I think Anthony will get the call before Mayer, unless he's injured, when an obvious opportunity arises.
Even if a middle infielder were to get injured, the Red Sox could move Ceddanne Rafaela to the infield and call up Anthony before Mayer. However, as referenced before in the Anthony section, the Red Sox should be looking to get creative soon with how they can get their top prospects in their major league lineup with Casas out for the season.
While the media has branded Mayer, Anthony, and Kristian Campbell as the "Big Three" Boston Red Sox prospects (the "Big Four" before they traded Kyle Teel), I would say Mayer is a tier below Anthony and Campbell in terms of short-term and long-term fantasy impact.
That's not necessarily a slight to Mayer, as I think he is a good prospect, but Anthony and Campbell are potential future superstars.
I have been up and down on Mayer throughout his professional career. After getting drafted fourth overall in 2021, he was compared to Corey Seager like every tall, lefty, hit, and power over speed shortstop.
He had a strong start to his professional career, with a 139 WRC+ across Low-A and High-A in 2022. His stock dipped in 2023, when he had a 96 WRC+ across High-A and Double-A, but it bounced back up in 2024, when he had a 139 WRC+ in Double-A.
This spring, he actually outperformed both Anthony and Campbell, with a 156 WRC+, leading to some speculation that he could be breaking camp with the big league club and not Campbell.
Like Anthony, even though he is still in the minors, he's not pouting and is putting up quality numbers at Triple-A. He has a 116 WRC+ with seven HRs. He's also kept his strikeouts in check, as his K-rate is around 20%, like it was in 2024 (it had been around 25% earlier in his career).
Marcelo Mayer is UNREAL!

If you're looking for a shortstop with more power upside, Mayer makes for a solid upside stash in deeper leagues.
